I am the proud original owner of a 91 Turbo with 115k miles. After changing my rear rotors and brakes this weekend, I had her up on jackstands and put it in gear to test the brakes..
After I put it in gear, I noticed the right wheel moving
much faster (2 or 3 x faster) than the left wheel.
No brake noise or anything.. And both wheels move freely when in neutral.
I am getting ready to change the tranny fluid, likely with Redline MT-90. Not sure if this could be a sign of a problem with the trans.
Is it normal for both wheels to not be getting the same amount of power?
Should I be concerned?
Any advice greatly appreciated.

This is a fantastic message board! A wealth of info.
I've searched for related problems and cant find any info.

Thanks!

Hello Steve,

I'm glad you appreciate the forum. It is typical of most differentials that one wheel will overcome the intial inertia (say that three times fast) and begin to rotate before the other. With both wheel free to turn, there is less resistance to send all the power through the spider gears in the differential, than to divide it between two wheels. Made sense to me when I started, but the more I say, seems like the less sense it makes.

Anyway it is normal for one wheel to turn and it will turn twice the indicated speed on the speedo.

Its not a sign of anything. Its perfectly normal for 1 wheel to turn while the other doesn't, or for the 2 to turn at different speeds.

That could be the result of one brake dragging, but that isn't necessarily so.
