The trans has a stock LSD. I believe the tranny code is y21. The thing is that when i jump on it (but not hard enough to make the tires break loose) the car pulls to the left pretty hard..almost like it floats to the left. But when I let back off the gas it corrects itself and goes back to the right or center position. But when i really get on it and break the tires loose the car goes straight. Why is the car pulling to the left? Curious what your thoughts are and why it pulls to the left. A guy told me that all the cars he has driven with oem LSDs perform like this. Also, the car just had an alignment in july and nothing crazy has happened to it since then. Thanks for any help.

Nothing about a stock LSD is going to make the car actually pull to one side or the other during load unless it is damaged. I would tend to go with either tread wear on your tires or something along the lines of suspension. Could even be as simple as a blown strut. You should put it up on a rack if you have that ability and check out under the car ?

Kind of what i thought as well. Its weird that its only under acceleration though and not just normally when im driving it. ( I just bought the car). If one shock is adjusted stiffer then the other, could that have anything to do with it? Car was just aligned in july and seems to drive straight otherwise. When the tires spin while really getting on it in first it goes straight, it just happens under acceleration when the tires arent spinning.

when I first installed my new lsd if I accelerated hard it would pull to the until after a while, I think its break in period

what age is the car? condition of the rubber bushes. mine were shot and afer fitting a skunk2 camber kit and adjusting my car drove straight but when i put the foot down the old bushes would twist and make the car pull left until i let off. fitted polly bushes to the front and never had a problem since, just somthing to check.

wierd...but before gettin into tearing apart the transmission, check the normal stuff, such as the suspension geometry, make sure no shocks are blown, springs are seated on the shocks correctly, etc etc, go check out the alignment again, and make sure that when the guy (or girl ) is doing the alignment that both sides are the same for toe etc.
Also the easiest thing to check would be the tire pressure, tire wear, make sure both tires are the same (i know its stupid, but hey you may be retarded )

good luck

passenger side was 5psi lower then the driver side. But wouldnt that make it pull to the right? Guess i'll jack it up and look for anything extremely out of the ordinary.

What car is it? Just bc it has a LSD doesnt mean it has equal length half shafts.

LSD doesnt mean a perfect 50/50 split

This is a common occurance when a car has weak or broken lower a-arm bushings, or radius arm bushings. When you load down the suspension during acceleration and deceleration and it pulls/acts oppositely its because the lower arm is shifting and changing the Caster, Caster setting of the alignment is what causes a pull. So most likely if you change the bushings this will stop.

Unless you have some goofy problem with the torque diffrentiation in your LSD.

bump...i'll check it out. Thanks for a great answer

What a-arm? you mean control arm? and whats radius arm bushing? is it shock bushing? no such things in parts names, do they have other names?
thanks,

agrn93ls

yes i was refferring to lower control arm. common term in the mechanical business is lower a-arm ( old timer terms that have worn off on me ).

a radius arm is also referred to as a strut rod. its basically the same thing as traction bars. it is a bar that runs from the frame or subframe to the lower control arm to brace it and stop any forward to rearward movement. it is also used to control/adjust caster. caster is the relation of the imaginary vertical line between the upper and lower ball joints, that line and whatever its setting is, is what affects an alignment-caused pull. tires are usually more common to cause a pull than alignment is. unless you have worn out suspension parts, well NM the reason worn out suspension parts cause a pull is because it affects the caster, so all the same.

thanks, thats wonderful!

This problem also occurred to me. Not sure what it was. Never got into my suspension to check things out, but if that was the case, then I don't see why the LSD that I installed would do it and an open-diff wouldn't.

I just came to the terms that something was screwed with the OEM LSD, and that was that.
