Still trying to figure out how to adjust the camber. That is without buying the weird off set ball joints l have heard so many bad things about. Please enlighten me.

Well I have seen the off set ball joints just never anything good about them. And the EMF ball joints at over 500 bucks is a bit steep to experiment for me. My current ones cost less than $200 and sti

Ohh boy i started a can of worms with this title. But to me i have finally accidentally made my truck drive better to me then some newer cars feel to me. Personal opinion i guess. But non the less i think it is pretty good and i would rather drive it then the recent new cars i have drove. I can literally lay my wrist on the steering wheel and drive down the rough uneven dished roads we have around here without any problem or feel like i need to grip the steering wheel. I hope i can help someone else with what i have learned.
Caster is less important for now but in the direction of caster you should be ok with no change from a 0* caster that will be left for the other side but you still need to know the reading! If you did not have a 0* bushing in there you will have to do some math to figure out where a 0* caster change would of been with a 0* bushing and put it back to 0* change from the AXLE! If you can't figure this part out just get your self a couple 0* bushings install and start over! Me trying to explain the math would be pretty long. As i said in my case i was only 1/2* off on camber so i orientated the bushing to only change camber. Yours maybe off 3/4* you just use a 3/4* bushing and install to only change camber. WAIT DID I JUST TELL YOU HOW TO CHANGE CAMBER ON A DODGE??? Told you it can be done. Ok now check your work on that side. Yes that means putting both sides back together put wheels on make sure the side you just changed is strait with the rear again then set back down on the turn plates. Take a camber and caster reading! Is camber within my specs below? yes go on if no calculate your change still needed and get it there. You must be very PICKY! Make sure you write down the cater and camber readings. The caster number is not a worry yet you just need to know it. Now after you get the first side camber set here comes the hard long drug out part. The 2nd side. I bought one of moogs adjustable ball joint bushings part # K80108. You may need one of these for the first side if you are in between a * but i didn't need it. Trick here is you can turn the bushings just a bit to help you out. Not a full setting over but just using the slop the bushings have. Now you simply make the 2nd side match the first side
yeah that wont be simple trust me. If you started with a 0* bushing simply use the chart given with the moog adjustable bushing to make the 2nd side caster and camber match the first side you did based off the numbers you wrote down from the first side. Simple? seems like it but reality is you don't always get the change the chart says. So you will have to install put wheel back on, straiten tire with the rear, set it back down on the turn plates take a reading then adjust again. I did this over and over till i finally got caster and camber the same as the first side. Again the slop in the cogs may help you with the very minor changes. The last few times i didn't need a full 1/4* or even 1/16* of a degree so i could turn the hole bushing watching the movement of the knuckle and seen if it would help. If so id set it there and take another reading. This will be a royal pain to get 2 directions just right! Keep trying eventually you will get there. This took me a few hours before hitting the sweet spot! I have turned wrenches for a lot of years but this will be time consuming! It may take you a day or 2 before you get it but it is worth it i think. Now after you get both sides done you need to pull off your tie rods and make sure your knuckles move as free as they possibly can! Remember moog are tight anyways but don't just write that off make sure the knuckle moves as free as it can. Again this is a MUST!
I also found in all my messing around a cross caster as little as .2 and a cross camber reading of .2 will make a heck of a pull when working together. That means the less caster on left and the higher camber on the left will pull left pretty hard even with the road crown. So you want the best be more precise! .75 is a long ways off to me.
This was done on a 94-99 truck. For 2000+ trucks instead of bushings you will probably need offset ball joints or maybe someone makes a adjustable ball joint??? There is bound to be a way.
First the truck is a 1995 dodge ram 2500 12v with a service body full of tools and a lift gate. Pretty darn heavy. Sitting on 265/75-16 Pro Comp extreme MT tires and stock wheels. No lift! Has been converted to the 99 HD tie rods. You know the T style. I have been converting to this for over a decade before every one found out the 3rd gen T style. Either way you need the T style setup how ever you get it. For now there is no steering dampener! You shouldn't need it for a properly driving truck! But i still plan to add one. Also you will need the steering gear sector shaft brace! Lastly i still have a OEM steering gear! Actually i went back to the OEM one from a 250,000 mile parts truck. What i have found is most any rebuilt steering gear is worthless. They either have more slop then the old one, they leak in a short time or they just plain was not rebuilt properly. If yours leaks put seals in yourself! You don't need a rebuilt one over a leak! I have also tried a few aftermarket brand new "upgraded" steering gears with no luck. They throw off the geometry and you gain bumps steer. I guess that could be fixed that is up to you. But in my situation best was a properly adjusted OEM steering gear that has not been touched by a rebuild place. Thats all for the truck.
Leading up to making this truck drive so good.
Long story but the short version is fighting with some tires and some bad alignment jobs from alignment shops i got pretty mad and decided i was going to do it myself! Especially when alignment shops leave ball joints loose! Now being raging mad i did lots of searching and finding lots of specs mostly close to Thurans fabrications specs. Then i searched all kinds of vehicle specs from race cars to class 8 trucks, motor homes, even checked out fords specs being they used the same front end. One thing i noticed is the dodge and ford guys say it is all in the caster and you need more while motor homes wanted less due to wind pushing them around! I also noticed fords had a much tighter alignment spec then dodge. One of them being CAMBER! Camber on a dodge? Not even Thuren says anything about camber! I never found a camber spec just searching the net for a dodge. Most things i read say it is not adjustable on a dodge or that you must bend things. NOPE! WRONG! Camber is adjustable! Also i have drove plenty of fords many drove pretty good why can't a dodge drive that good with the same axle? So after all this i came up with a plan to make it drive at least as good as a ford!
Condition of your parts!
Everything must be in good shape as in no slop, steering gear adjusted properly, steering shaft in good shape, and the ball joints must not be bound up! This is a must! As i found out just fallowing instructions is not good enough even moogs. Your best bet here i think is get EMF ball joints and he has a great video showing how easy the ball joints should move. this is a MUST! Heres the video. https://www.youtube.com/watch?time_continue=217&v=us0z3s_VYKQ&feature=emb_logo I have moog ball joints which i have found to be very stiff on there own so this affects it some. Lucky me i have around 40,000 miles on mine so they are not as stiff as new and new ones will be to stiff even after doing everything right! So if you are using moog or any ball joint that is pretty stiff you may not get the results i got till they are well broke in. But you must at all cost make the knuckle turn as easy as it can which might mean doing even more banging on things if they are not EMF ball joints. You still need to use your ball joint manufacture torque specs tho not EMFs unless you have EMF ball joints. I had to do a lot of hammering to get these moogs to not bind up at all! Even with 0 binding they will not become as easy to move as EMFs ball joints. They are simply built with to much friction.
Tools you need.
A set of good turn plates that shows the degrees! A caster camber gauge. I used a small magnetic one you stick on the hub. I happen to have one that is to small to fit the dodge hub so i took a chunk of 3/8" steel to the local machine shop and had him make it fit the dodge hub and the caster camber gauge then installed more magnets. I will upload some pics of it later. A tape measure that is in good shape! Lastly a helper. I wouldn't use any caster camber gauge that mounts on the rim. Rims are not very true at all so the machined part of the hub is much better. You may need to get some off set ball joint bushings and or get 2 adjustable bushings like moog #k80108. Here are the instructions for using it to set Caster AND Camber. Give you a idea how it works. https://www.catalograck.com/ImgVD/PRD/44-5032ins_1-up_18571.pdf
HOW I DID IT!
I first parked the truck on the turn plates and setup my caster camber gauge. Make sure the tire you are checking first is perfectly lined up with the rear! Use a string line if need be. If your toe is off you may need to turn each side separately to get your reading. Take the readings and write them down for both sides. You will need a buddy to turn the wheel during the caster check while you watch the turn table gauge for how far your caster camber gauge tells you to go. Make sure you read and understand your caster camber gauge instructions perfectly! I then lifted the truck and pulled the wheels off to see the top ball joint bushings. Pull them out! Make sure you know which one goes where and the orientation! If you have anything but a 0* you must note the orientation! Now pick a side that looks easy to get camber moved into spec. Mine was the right side as i was only a 1/2* off on camber from my spec with a 0* bushing and i happen to have a 1/2* ball joint bushing the alignment shop removed.
Time to set toe! Now get your buddy to hold a tape perfectly in the same spot on your tire every time. Find a spot that makes it easy to repeat. Mark it! You must be perfect here! Just the thickness of a line on that tape is to far off so be VERY PICKY! Then simply jack up the vehicle measure across from tire to tire then turn the tire around the back side and check with the very same marks! This will take out any wheel run out you may have. Remember it must be PERFECT!
Lastly caster! You matched them side to side now it is time for total caster! On the turn plates i ended up at 5 1/4* since the turn plates lifted my front wheels. In reality i know from previous readings on a flat floor it is around 4* caster. This you can adjust with your pinion angle eccentrics. Most believe it is the caster adjustment and even thuren states that. Well yes use it to swing caster to where you want. Probably near 4*. less if you want lighter steering more if you want more stability! Want light steering and stability? Search up on this forum for the power steering pump flow control valve mod. You can make lighter steering by simply adding more power steering flow. NOT PRESSURE only flow. Watch your pinion angle tho. If for some odd reason you can't get enough total caster without having drive shaft problems you can use the bushing to gain more caster or offset ball joints on the newer trucks. This is what the alignment shops actually use to adjust your caster anyways. Now adjusting these eccentrics don't just turn them evenly with the lines you could bind things up. Most not but in my trucks case to keep both eccentrics carrying the same load one is pointing up while the other is pointing forward! Now this seems bad but i know this truck had hit something hard at one time so it is no surprise to me one side is different by a lot making up for what ever is bent. Each eccentric should carry the same load. I did this by feel and watching my control arm bushings. If i had put both of mine pointing in the same direction one side was twisting forward and the other was twisting backward. Not good!
If you take this to a alignment shop they will likely charge you a lot more then a flat rate or tell you no lol But hey ford specs are as close as .25* where dodges are all over! the key here is to be perfect as can be! And i bet the camber is a big part of it as even having cross caster and toe set to Thurens specs i did not like. But they don't factor in camber at all! Camber being set close with cross caster and toe really made a difference in my experience. The thing likes going strait! Also Thuren states at the bottom "IMPORTANT: Especially regarding the 2003+ years, cross-caster is welded into the axle. With the cams close to in phase,do not worry about up to .75* more caster on the passenger side. This is permanent, normal, and can not be adjusted out." Well that is simply not true! Cross caster which is the caster from one side being different by up to .75 CAN be adjusted out with the ball joint bushings! Or in case of the newer trucks then 1998 can be done with offset ball joints. Or maybe someone makes adjustable ball joints??? In my experience i had .75 cross caster on this very truck and with camber being off another 1/2* fighting all that cross caster it drove strait on a nice flat road but ones you hit roads that are rough uneven and or dished it made the truck get really awkward handling. Caster and camber effects are different with different amounts of weight. So a road that is changing the weight on one side only at a time makes it feel very awkward and makes you need to grip the steering wheel. I believe the folks at Thuren are probably great people and want to do there best but they must not have figured out cross caster and camber really are adjustable. But who knows they probably live where the roads are not total crap so they have no reason to dig any deeper. I would also assume there test trucks do not carry the extra weight mine does which only amplifies imperfections. I could see a empty truck with such specs would seem pretty good on good roads. I want mine to drive good on bad roads while being over weight
Thuren also states "2000-2002 year trucks can upgrade to the 2009-2013 OEM Mopar steering.1994-1999 can not as the pin tapers are off spec.1994-1997....All trucks had Y-linkage steering from the factory, so you must have aftermarket continuous tie rod steering to use these specs, for those years. If you have Y-steering, use OEM specs." Again this is wrong 1999 had a HD steering setup just like the 2009-2013 has just with the right taper for the 94-99 trucks. So you just buy OEM tie rods and drag link for a 1999 with the HD steering. Heres the link to read yourself. https://www.thurenfabrication.com/media/wysiwyg/THUREN_FAB_ALIGNMENT.pdf Again i have nothing against Thuren. I just learned they are not 100% right either. Nether am I.
Ok finally the specs them selves!
CAMBER 0* to -.1* Yes it must be that close and not on the positive side! If one must be higher make it driver side to fight road crown.
Caster 4* give or take driver preference! search steering pump flow control valve to make the steering easier again.
Cross Caster .08* at most! unless you want to fight the road crown then do as you feel you like! Vehicle will pull to the side with less caster.
Total toe .05* at the most!
Thrust angle .01 at the most!
Extra important notes.
The more caster you use the more wear! Bigger tires will be more wear. Use good parts and you will probably be ok. If I didn't already have good moog ball joints i would of bought EMF ball joints hands down now that i know how much ball joint stiffness makes these trucks wander.
Lastly Sorry for any spelling or grammar errors. That is not what i am good at. However i think i am somewhat good at fixing things as i do it for a living. Seems like a good trade off to me? If you want to help me out and make a corrected copy of my post and send it to me i would really appreciate it and edit this one so it is easier to read.
