sideways on accel/decel
i've always noticed that when weight is transfered to the rear of my fd, the nose pulls left, weight to front nose pulls right. never thought much of it until it got real cold the last few days and it became much more pronounced. the pull is visible when looking over the hood of the car, and has a very unsettling effect on the car when accelerating/deccellerating in a turn. what causes this and how can i stop it? oh, car is stock with recent rebuild and 130k on chassis. don't believe the shocks have ever been replaced.

replace the shocks for frick's sake - that's more than likely the culprit. Torque is what does it (I assume that when you decel it's while it's still in gear) - that's why you see drag cars lift one wheel off the ground when the accelerate hard... the engine is trying to turn the car over.

if it were tire or alignment problems, would it not pull one way all the time? with the wheel in the same position, the difference between accelerating and decelleration produces a noticeable change in the direction the car travels. its as if i turned the wheel an inch in that direction.

Listen to Max & check your tire pressure. If the pressure is ok then you could have lots of slop in the bushings changing the rear toe angle under accel/decel making the car basically crab...

When you brake, the front end comes down, creating a specific wheel alignment. When you accelerate, the front end comes up creating a different situation. Either way, the car should go straight. Tire pressure is easy enough to check. Start there. That probably won't fix your problem. An inspection by a competent alignment mechanic should tell you if there are worn parts, or a bad alignment, or both.
The shocks can't be any good with that many miles.

Go with Max. I discovered a (fortunately) slow leak in one of my back tires because when it lost enough air pressure, the tire's rolling radius shortened and this created unequal torque. On even light acceleration / de-acceleration the car wanted to turn back and forth exactly as described by tulin.
