so today i realized something really weird while driving on the highway.

So i'm driving down the freeway going straight. My foot is on the gas on cruising speed and the steering wheel points a little right. When i lifted my foot off the gas.. the wheel is straight.. I gas it once again and it feels like the right rear wheel is pushing the car more than the left rear wheel so i have to compensate by pointing the steering a little to the right.

I know that the left rear wheel is at least pushing the car because if the right wheel was just spinning it would just be driving very very awkward.

Ive got a 2 way lsd and had an alignment 2 months ago. I have more camber on the right side than on the left rear and the inside is a little. Tires are pretty bad on the both rear too.

What could it be? Maybe i'll run the wheels on jackstands and see if both rear wheels are spinning consecutively.
