Yes for my particular driving I am starting to have doubts about getting great fuel economy. Maybe I look into the running of propane. I am just bummed about the high ___ diesel prices currently. I think they are inflated in my area because of Harvest time.

For now I probably just stick with the KN seems how I have 2 filters and it's how I bought the truck. My tire size is 285 r16's. I drive about 50 miles a day. I was hoping with the 3.55's and Edge of getting into 21-24 mpg range. maybe that is not realistic. Truck is sitting right now while I drive my Honda go kart. Once winter hits I will be driving truck 100% of the time.

With fuel hovering at $4.25 per gallon I am looking at getting a set of 3.55 axles instead of the oem 4.10's I have been getting a constant 16 per gallon for years. I do pull a 38ft trailer 5-10 times per year. The complete axles are going to cost about $800 bucks. Am I looking at fuel savings the correct way or am I just gonna put to much strain on the Auto. Pros and Cons? 2001 2500 4.10 diff's with LSD automatic trannsmission 169,000 miles on truck and no current mods other than KN filter. thanks

I feel stupid to even type this but I took a road trip today and the whole time I was thinking damn my truck is riding like a dump truck. I stopped after 70 miles checked tire psi only to find they were at 90 psi. I reduced psi to 50 psi and truck drives and rides like a champ. What the hell have tire companies come to is all I can think and yes I should of checked the psi myself. I have been checking wheel lug nut torque because of the different rims never dreamed of over inflated tires. Just glad it's resolved.

Well finally picked my truck up yesterday and took for a test drive with my experienced alignment man. Truck is at least driveable and safe. Still not at 100% but def. can stand driving again. Also he is willing to keep adjusting he just wanted to know what quality I was specifically looking on my truck. On the test drive he at first told me he had done nothing since I brought it to him. when I drove my truck it only wondered about 10% of the time and it was a windy day so I was dumbfounded. Later He confessed to making several adjustments and WOW the truck is driving almost perfect.Truck has 169,000. miles on it at 110,000. I put on new upper an lower ball joints, Front springs for 2 in level, New front shocks, Track bar.I was told that every part of my steering system including the gearbox has some play not to the point of unsafe but when you add it all up with my wide tires I might be at the best driving until I fix and replace some items also with my offset rims and bigger than oem tires my truck rides on the humps of the road from having a wider wheel base. My plan is to over winter is to replace all the common wear items including the steering gearbox. In the spring get aligned again and I already know it will drive perfect. So thanks everyone, and for those who have a good vendor for the parts please share.

Well finally got my truck into the real good alignment man. I was suppose to pick it up yesterday, well he left me a messege to call him asap this am. don't sound real good. will post what I have to end up changing what happens.

Well to answer about the alignment I just had the front end aligned. I have measured from back axles to the front and they are equal. I really think this guy who aligned it put my truck to factory specs. and called it a day. I am not sure if he has the skill to compensate for the offset and 2" front lift which does effect things. I have another person who is real good and I don't know why I didn't just have him do it in the first place. I might just eat the 70 bucks and get my truck to a experienced align guy. The shop I took it to wants to try and keep fixing it I asked for a refund they said no. All I really want is to be able to drive my truck. I thought I was saving time and now this has turned into a 2 week ordeal.

Ball joints are good, track bar new, not really that much movement in rest of steering. the thing that gets me is before the alignment I had a constant pull to the right started about 3 monthes ago. No weird tire wear just a constant pull. If it is in fact in perfect alignment and the gearbox is allowing it to wonder the road sounds like I will have to look into that. I guess when I told them to align it. I thought they would have checked. 50,000 miles ago when I put all new ball joints and track bar on and the 2in lift in front the truck drove the exact way. I took it in to a reputable place in another city and they were able to align with no problem. I will update once I get resolved thanks for the help guys.if the gearbox was bad or out of adjustment wouldn't it have been wondering the road before the alignment? thats what gets me. Why would they have even aligned it with so much gearbox play I have been told it takes a knowledgeable person to get to drive correctly.

Well first I had made a mistake the actual offset is 1.75 in. per wheel. the offset is away from the axle, but to me that isn't much. I put my original same size tires and rims back on and I do not have a constant pull to the right. Only I still have the truck wondering all over the road. 45-65 is the worst. I tried several different surfaces also. bottom Line I think they should be able to get the new rims and tires to work. Because truck drives worse than before. Thanks for input.

well I still have my original rims with tires that I am going to install on the front today and see if a difference. I just have seen so many pick ups with a off set like mine that don't have this driving issue. Thanks for the input.

:banghead: well it's a 2001 2500 cummins with a 2" spring lift in the front otherwise stock. After 50,000. miles my Dueler AT's needed replaced. I bought some used rims and powder coated. well they offset out about 3-4" per side compared to oem rims. tires are a 285/70/16. I installed new tires on the diff. rims and had aligned. I can't even keep truck going down highway at 60 with out about crossing center line. it is all over the road. Is all this because of the wider offset? If i have to go back to original rims I will. The truck is not driveable like this, I look like a drunk going down the road, it will randomly go either left or right 2-3 feet. It droove like this after I 2 # lifted it, then aligned fixed. I can't believe they can't align to drive correct. any help much appriciated.
