I put new green bearings on my old axles. The third member spins really smooth until axles go in and tightened down. It's so tight my McLeod clutch just slips and car won't hardly move. Turning the axles by hand with wheels on and car jacked up requires considerable effort. Is it possible the shop installed the green bearings too far up on the axle causing the axles to actually touch inside the third member? At this point I am not ruling anything out. It is a 741 case with a clutch type sure grip and 3:91 gears.
