04 Dodge Ram 1500 lift kit problem

HomeBrewer · 2006-07-22T12:11:50+00:00

I just installed the 2002-05 RAM 1500 4WD 6? PERFORMANCE SYSTEM made by Fabtech and put 35x12.5 BFG MTs and 17x9 MT classic II rims (see pic here: and ). and I have 3 major problems:1). I had the truck aligned before installing the lift (according to lift instructions) and all was fine. I installed the fabtech lift and the truck is now pulling hard to the right. I had the Dodge dealer align the front end and it is still pulling to the right. I returned it to the dealer and had them verify and it is within (factory) specs. Did the fabtech lift change the specs on the camber, caster, and/or toe? I will contact Fabtech directly about this, but I doubt they will admit to it. I think they would have included this in the instructions if the specs changed, right? If they can't supply the new specs - how do I correct the problem? Can I get a shop other that the dealer to align the truck without using factory specs - or - is there no place to start then?2). I have a vibration at 40-60MPH that is not very nice. (no changes were made to the rear drive shaft, etc....)What components could cause this? I had the tires balanced and they used the stick on lead weights inside the rim. Are tires this big able to be balanced like that? I thought there was something that goes inside the big tires that balances them.3). I had the dodge dealer recalibrate the computer / speedometer to compensate for larger tires. Now the cruise control only works up to 45MPH (I can only turn on cruise below 40 MPH and then using the buttons on the steering wheel accelerate up to 45MPH before it shuts off). Again, I returned it to the dealer and they says it's not the computer recalibration. They have never heard of the problem. I know it has something to do with the big tires and the computer recalibration, because the cruise worked fine just before the recalibration.Any help or advice would be appreciated.

Really, then how come NONE of the Rostra electronic cruise control units I sell and install have no vaccum line hook ups, NONE use MAP, vaccum, or manifold pressure? They will ALL engage at 25 mph or higher, etc..

Oh hell you know it all.

I tried it . even in "2" with 3200 RPMs the cruise still shuts off at 40 MPH. In the service manual it says it is designed to work above 30 MPH, but I was testing it this morning and had it set at 25MPH and it worked. I'm baffled but the dealer is supposed to fix it on Thursday.

Yeah... Definately a vacuum problem. Def-def-definately. Uh-oh... three minutes to Wapner...

Hey Snoman... any other bright ideas?
