Wheel spin when car is lifted????

[CrazyUglyCoyote]

Whenever I jack up my car, my front wheels turn about an inch. does this mean I have a LSD or somthing? My mechanic saw it happen to, and he had no idea what was going on.
Its a 1991 Talon TSI AWD. Ive only had the car foe a couple weeks now, I bought it from a middle person, who knew nothing except that the engine didnt run.

i doubt it, probably the rears turned an inche as it was jacked- they're connected so it spun the front anyway fwd cars get aftermarket LSD for better traction, but awd cars likely wouldn't bother. maybe my first statement was wrong, and perhaps they destroyed the center diff and then welded it together, so the rears spun the fronts
anyway, if doesn't have tons of other mods then likely no special LSD

Are you sying it does this when you just jack up the front or when on a 4 point lift?

Front only: The car is probably rolling forward a little, and since the front and rear wheels are connected, you see the front wheels rotate a little.

All 4: Just the drivetrain unloading

Either way, not a big deal.
