I have 3.73's and about 95K miles on the rear. The rear of the car wants to kick to the side when I shift gears. I have a post in the suspension forum:https://ls1tech.com/forums/suspension-brakes/491411-why-does-my-rear-want-kick-side-when-shifting-gears.html
Everything as far as the suspension is tight, and someone suggested that it was my posi / limited slip going out. Any way to tell without opening the rear?

Actually there is a way of doing it with a dial torque wrench. Lift one of the wheels(the other on the ground). And with a special tool from the dealer connect the torque wrench to the lifted axle and turn the axle until it stops and get Your torque reading. Then compare that torque reading to the specs that the dealer will give You. I know I have the specs in some old U.T.I. notes Ill look for them and PM You if I find them. But it might be different for Your application because I believe Your car has a torsen diff. But I know for sure thats how You check the Auburn diffs.

How likely is it that I could find that tool for rent from auto zone? I imagine that the dealership won't let me just borrow one, and they'd probably charge me to check it.

Maybe it isn't installed correctly? Just trying to figure out why mine kicks to the side. Could that be it?

Mine does that too, and the back wants to pull to the left when I really get on it. It always has, I think that's just a side affect of the torque, and probably the cheap factory torque arm and rubber mounts.

I'm not convinced; I'm not putting down any huge numbers (LT's, TD's, & boltons), and I don't feel that the car should be acting this way. I'm gonna see tonight if I'm driving a one wheel wonder or not. BTW, I have poly mounts and stock torque arm.

I would imagine that if your limited slip was going out that while doing a burnout, only one tire would spin and the other one would not. Something to that effect. Or maybe it would catch here and there during the burnout.

if you have a 99 car you should have a zexel torsen and they do have clutches that split the power to the wheels they use a set of worm gears in the diff. so they never wear out like a auburn does. but their ability to split torque is only around 2.5:1 i think. so in their fully functioning form they can do a one legger burn out from what I heard. also I've been told that you can break the worm gears inside and the car will still drive fine but the diff will function as a one legger. also keep in mind that if anybody tells you to jack the car and rotate one tire and the other should turn the same direction, this is a test for a preload clutch type(auburn, spicer) the zexel will turn the opposite direction whether it is good or bad.
