2nd Generation Dodge 24 Valve Powertrain

99 3/4 ton diesel 4x4,241hdwhen in 4wd i have loud clunking under front of truck.iv'e checked in the diff and both axle u-joints and front bearings.all look good, could it be the front drive shaft u-joints making this noise?any body had trouble with this?thanks in advance

Ok my dash indicator for the 4wd is flickering. It comes on when engaged and takes a long time to go out when out of 4wd. It appears to be out since I can not feel the feedback in the steering wheel. It did not have this problem last time I checked it. I just got the truck a couple of months ago. My cruise control works, it does seem to take a little time to change modes but not really long and i have no reference to another truck. I do not have the vac solenoid on the front axle on my truck. Any thoughts? Thanks

I went snowmobiling the other day and now have popping going on inside my front end when in 4wd and there is pressure on the drivetrain. I believe it is the CAD as I have already jacked up both sides, checked all 5 U joints and turned the driveshaft (Pinion feels tight and driveshaft turns with ease). All U joints look good and have no slop in them. The transfer case has very little slop as well. The only thing left is the CAD. I think the diaphragm inside the actuator has gone bad because I can suck on the side that pulls the CAD over onto the disconnected side and it holds the vacuum. If I suck on the other line, it does not hold vacuum. Is there anything else I'm missi…

When I use the 4wd the light in the instrument panel has a mind of it's own. I am going into 4wd fine but when i first used it, the light wound not go out when i shifted back to 2wd, until i guess it shook whatever sender it has free (Gumed up?). The other day it didn't come on at all when i was in the snow in 4wd. Does anyone have any fixes or test? Thanks for any help. just want it to work the was it is suspose too.:confused2:

Hey guys i am new around here and have some questions! The 4x4 will not engage on my truck. i understand the vacuum operated system and suspect that this is where to start on fixing it. however, my ABS and parking brake light are always on as well. is there anyway that the two could be connected? when i put the truck into 4H there is no change in the steering and the lights do not illuminate. in 4L still no lights or steering change but it does go into low range. any help you could offer on this would be great! also if anyone has experience trouble shooting the vacuum system or has a diagram i would appreciate the insight! thanks in advance guys.Also not sure how to do a …

Hi all, I have the POSI Lock cable actuator for my 4x4. I didn't install it, it was on the truck when I bought it. I am wondering if anyone else who has one has had issues with the 4x4 indicator light coming on when its not engaged? When I bought the truck the light didn't work. I soon figured out that it just wasn't connected and fixed it. After that the light would sometimes flicker while driving, but I could usually fix it by twisting the cable until it was snug. Today the light was on but very faintly and I couldn't get it to go off. If I pulled the cable it would come on all the way, but when I pushed it in it would stay on very faintly. Later in the day I had t…

Now I have problems with my 4X4. I was driving in some deep snow and there was this small clunk and no more 4x4:banghead: Shifter works fine and there's no visable problems. Any suggestions what might have happened or where to look first?

Does anyone have a 4x4 locking /free hub/spindle kit on their truck? A guy's dodge truck in the shop has the yukon free spin kit installed. He said he gets better fuel mileage and he can feel the difference driving around I always thought about installing one of these kits. Cant remember what brand I was looking at

I'm not getting any indication on the instrument cluster that the 4 wheel drive is engaged but everything works fine,where is the indicator switch

Will it damage my 4x4 if I install new tires on the rear only? All tires are factory oem size.

Hi guysI know been discussed on this site and others - but can't work out next approach.I have drawn a diagram. Attahced here.Whats the green wire for - can't find details on that anywhere and why just hanging loose - should be plugged somewhere ?Thoughts of next course of action ? 4x4..doc

Folks it seems like as soon as I fix one thing another one breaks! I am having 4x4 issues with my truck. When shifted into 4-high or 4-low the 4x4 light comes on on the dash but the front axle is not engaged. The transfer case obviously shifts into 4-low so I pretty much have a 2-low scenario. I started checking vacuum lines but my HVAC and cruise work fine. The 2 lines that come up from near the transmission are what confuses me. One of them ties into the main vacuum line on the cowl. The other has a 90 on it but is not connected to anything, and I can't seem to find what it would look to. According to the vacuum diagra…

Ok guys I honestly hate to start another thread but I have a serious problem. It is the dead of winter and my 4x4 won’t work! The engagement stick moves into place but no dash light or 4 wheel drive! I need to get this fixed ASAP! I used it last week so it worked fine then. Help?

My 1998 Dodge RAM 2500 Truck just stopped dead in the street and won't even try and start. IT has a 5.9 L inline 6 cylinder, 24 valve Cummins diesel engine. I hooked up an OBD II and got the following error codes listed below. The forum here has testing procedures but the first requires the engine be running (it won't start) and the other require a DRBIII scan tool (expensive). I'm just trying to get this running again without major expense. Any suggestions on where to start without the DRBIII? I can check wiring as indicated. Do the combined codes point to a specific item that needs replacing (the fuel injection pump?) with certainty? One thing I looked as said e…

Alright so I might have done something really stupid. I put 2 bottles of the amsoil engine flush in my engine and ran it for an hour on high idle. I did this when I was checking/charging my AC system. I know that you are only supposed to do it for 15 minutes but the only thing in the amsoil engine flush is just detergents, no solvents so I thought it wouldn't hurt anything. After the flush I changed the oil with fresh 15w-40 and a new oil filter. So afterwards I noticed that when I was driving on the freeway @ 65mph, my oil pressure sat at 49-50psi. It would normally sit around 54-56psi but it seems that something changed. I'm around ~1840 rpms when the speed is 65mph. I …

I know this question has been asked in the past but I couldn't find the info. I have a 1999 Dodge Ram Cummins 2500 5 speed and to engage gears the pedal has to be pressed into the floorboard carpet. I have tried to sell this truck without any takers. There is over $10,000 in parts and labor above the price I paid for it. I have about $4K and my brother when he owned it put another $6k in it. Some of the costs in parts was not needed at all, Turbo rebuilt by Mid-West Turbo when nothing was wrong with it, Fluidamper added, Hi-Torque starter, Ceramic disc brakes and so on when good stock parts are more than good enough for a 20 year old ride. My brother is not a diesel mecha…

I was just wondering what kind of oil is recomended for my trans. I know what the owners manual says but what does that translate to at the parts store.

Well as much as I was excited about having an automatic and not shifting gears as much I can now say I hate my automatic! I have hauled two tractors now with my new truck and it absolutely sucks! I am planning to do a 5 speed swap at this point. Here is my parts list so far please add what you think is necessary and add any ideas or concerns about it. NV4500 Bellhousing (will the standard one work or will I need a special one?) Clutch (South Bend ConOFE) Clutch Fork Slave cylinder and resivor NP241DHD t case (will the DLD behind my 47RE work?) Driveshafts Shifter console and cup holder PCM ECM Gauge cluster (Can I …

Easiest way to explain is when i am down shifting into 3rd 2nd and 1st it sounds like its winding down, matching the rpms (as it slows, the sound slows). It does not do it in 5th and 4th and started not to long ago. any ideas of where to even start looking? thanks for any help, i am sure more info will be needed so just ask away

The issue I'm having has been going on for about 2 months now. Started out as a bad valve body. Pull the truck down in gear it would **** off I replaced the VB with a revmax HD and a triple disc converter with a low stall. Fixed that issue. But then about a week after while cleaning and prepping for paint I lost all power with symptoms of limp mode. Did some looking and codes led to low 5 v supply. Probes the wire and walls no 5v reference from the ecm. My question is is there anywhere else on the harness I can get a 5 volt feed to run to the map and iat to see if it fixed the problem before dropping the money on a new ecm. The truck spins over more now then it used…
