LSD or Alightment issue!!!

[VinhPham]

Ok....some background about my car:
It's lowered on H&R sport springs (.75" in the front and .5" in the rear), the car's pretty much stock except for intake and exhaust.

So I was driving this morning and notice the car was pulling to the right everytime I'm under power. I would be fine when I'm coasting or just cruising. But as soon as I step on the gas a little bit...the car lurches the the right. This happens around 40 MPH all the way to highway speed. It's not so bad but enought to make me wander out of lane if not corrected by steering inputs. I know this sounds unlikely but could it be my LSD not distributing power evenly to the rear wheels? I rebuilt by diff a while back (about 30K ago) and have been under regular maintenance since. Ohhh...almost forgot, alighment was done about 6 months ago when the car was lower and I don't curb the car or anything except for the ocasional bumpy road in the Puget Sound.

If you did not get your car aligned after you installed the springs. it need one. If you have not had one in a while, it needs one. When they do it, ask them to do it even on both sides of the car, Exactly and get a print out.

Second, tire pressure is the primary reason that the car pulls under WOT. Check it, Check it Daily.

I got the alightment done when I put the springs in and that was about 6 months ago. How often should it be done?

Im gonna check the tire pressure now.

On a different note...it pulls to the right even on very partial throttle and doesn't have to be WOT.

Tire pressures. Also check for a nail or screw.

I agree with the tire pressure thought. I have had it twice.

Tire pressures caused mine to do the same thing, make sure your gauge is a good one mine was off two PSI but the gauge showed it to be good, I got a different gauge and put the two PSI in I was off and problem solved.

prob tire pressure... i'll bet that one side is down to 15psi for it to be that noticeable.

It was the tires that did it. It was funny though because I've never experienced anything before. Thanks a bunch you guys. I though it was another alighment for me again.
