torque steer question

I have already posted a similar but I don't think it ever went through. Please excuse me if the other thread shows up.
First off, I have a 2000 TJ 4.0 manual. I couple months ago I had top gun customz install a 4" rough country lift and I put 33's on it (stock otherwise). I have what seems to be torque steer but I do not think it is coming from the front end. The reason I say this is because, if I look down at my left rear tire while taking off, I can see it move forward about 2" and then move back as the torque lessens or I let off the gas completely. Is the axle twisting under my jeep and is this normal? The only time I have a steering issue is at the moment I go from accel to decelerating or vice versa. Otherwise, the jeep handles perfectly (cruising speed, braking, coasting). Any suggestions would be appreciated.

Sounds to me like your front control arm bushings are shot. Is it making a lot of noise? That def does not sound normal in any way however.

You said the REAR wheel moves the 2". Why would someone say look at the FRONT control arms?

Sounds like the REAR AXLE control arm or the mount isn't attached. Is the bolt missing at the front of the lower control arm where it attaches to the frame or skid plate?
Is the mount where it attaches broken - like the welds are broken?

Could be they didn't torque it right, it came loose and the bolt fell out. It's probably something simple - but you'll have to go under and LOOK.


Also look at where the rear axle's left control arms attach to the axle. The bracket may be loose or the weld broken. You might have to look at it while it's flat on the ground, then jack up the BODY a few inches (not by the axle, and you only need to lift it up a few inches) to see where it's separating. Look at the front mount again while it's up.

When you accelerate or decelerate the axle should not move forward or backwards - or sideways for that matter. If it does, it's DANGEROUS. Find the reason before further damage occurs.

It should be pretty obvious.

Because I mis-read. Excuse me. I fail.
