I turned on my s2k while it was on 4 jack stands. The rear wheels start moving, but the weird thing is.... the driver side rear wheel was moving a little faster than the passenger side. I'm kind of worried

 

Ok, first DONT EVER TURN ON YOUR CAR WHILE IT'S SITTING ON F0CKING JACKSTANDS YOU F0CKING MORON ARE YOU TRYING TO KILL YOURSELF?!


...ok...with that said...it's normal. It's the way the diff is set up.

There were some kids at my old apartment complex that put their car on a jack and ran the car on it… Car slipped off the jack, and the car lurched into reverse across the parking lot and smashed into the detached garages behind them… no witnesses… Just blue paint from their car all over the bricks and bricks all over the ground… A week later, I saw them with the car on the jacks and figured out how the building was damaged and called the apt office & told them… They were subsequently evicted…Good cause they were the same little bastages that were breaking into cars there.. LOL

 

 

gosh..... its not like i was driving the car...... the car was leveled on 4 jack stands. i just turned it on because i was hearing some clicking sound, so i figured i could try to listen from the under the car.

 

Let me get this straight: you were UNDER the car while it was RUNNING IN GEAR on jackstands??
