Since I bought my car it has always pulled a little to the right under acceleration and a little to the left when I lift of the gas or put it in neutral. Really only noticeable at freeway speeds.

At first I thought it was a bad tire or bad wheel since the original rims where beat up a bit. I have replaced the the wheels and tried a new set of tires and even had the tires rotated to other opposite sides. I have also made sure the tire pressure is even.

I have gotten a few alignments and it aligns fine. It also seems to stop in a strait line when i hit the breaks.

What is the next step in diagnosing the problem? Could it be a bad rear diff? or maybe a bent frame or suspension part? Is there any way i can diagnose the problem myself? I just want some advice from you guys before I take it to a mechanic.

 

how bad is the pull?

 

Its hard to put it into words... It is not noticeable at low speeds when driving around the city. The faster I go the more I notice it. At 80 mph its enough that I can keep my car in the lane without using the steering wheel. Lift off to go left and gas to go right. I hope that helps im not sure how else to discribe it.

 

i would say your rear diff...mine had the same prob..would pull really hard when i would let off while i was going around 80....one day i driving pretty hard and the diff just exploded...got a new one...and problem was solved....s2k diffs are a peace of duke...but if i where you i would check everything befor gettin a diff in case.

 

I have the exact same problem MY02 . I switched to AP2 rims with 255's in the rear . This corrected most of the problem but I still notice it if I look for it

 

usually a tire will cause a pull on acceleration..if the tires arent directional, swap them from side to side and see what happens
