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
). and I have 3 major
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
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.
