i was at the dealer get a freebie check-up the other day. i heard a noise from the rear and it was a rear wheel bearing. anyhow, he has it on the lift with the car running and the rear wheels aren't turning. the front were spinning away (one side more than the other) but the rear were barely turning. the guy tells me he thinks the transmission is bad. it is a 5-speed. the car has about 43k miles, but i can't believe the trans is bad.

being it is a quattro, shouldn't at least one of the rear wheels be turning the same speed as the front wheel when the car is off the ground?

thanks for any help.

Not necessarily. If you have zero torque resistance at one axle (even with one wheel since the front and rear differentials are open), you have zero torque to the other axle. Since you had all four wheels in the air, you had essentially zero torque resistance at all four, so it's hard to predict exactly what would happen. I'll bet, though, that if you had stopped one of the front wheels from turning even with your hand, the rear wheels would have started spinning.

that is why he said the trans was bad. he held one front wheel and the back were still barely turning. the other front wheel was spinning pretty fast.

i'm still driving the car as i have an appointment to have the bearing put in. now i'm worried about the trans.

the EDL should have done something as well.. weird

The only time I've seen my car on a lift all 4 wheels were spinning pretty equally.

therefore only the front wheels would spin...your situation is pretty strange tho

MLOSU

nope, 50/50
