what did i do??

car is a 73 911e. I just put the motr and trans back in the car. motor had a top end rebuild. tonite while putting on my c.v joints, the axles were spinning while I was tightening them up. so I put the car in gear. but the axles still spin. what gives? what did I do wrong? or what didn't I do? I hope I wont have to drop the motor again.

If the other side spins in the opposite direction, that is normal for a non-limited slip differential.

Have someone apply the brakes while tightening.

really? I thought if you put it in gear, the car wouldn't move. I tried it on my 85 3.2 and tried to push it while it was in gear, and it didn't move. this might be a good thing. I hope you are right

I assume you have both wheels off the ground, car jacked up, while connecting the CVs on the 73.

Wayne's tech article: Pelican Technical Article: Replacing CV Joints - 911 (1968-89) - 930 Turbo (1975-89) "You may need to drop the car down onto the ground in order to tighten to this spec without turning the wheels."

Instead of dropping car, since I use a lift, I usually put someone in the car and have them set parking brake and push on brake pedal. then they can release and you can turn by hand.

yes car was up on jacks, I used the parking brakes to tighten the cv joints. I just thought if I put it in gear the wheels shouldn't turn. this makes me feel a lot better. I really didn't want to drop and reinstall the motor.

I just replaced the CV joints on my 77 and the wheels spun while in gear. I used the ebrake to stop the wheels from spinning.
