I am in a quandary. My 71 rear end does not turn freely. It is up on jack stands the wheels are off and with out the leverage of a breaker bar the hubs will not turn. The parking brake cable is lose the pads are not stuck on the rotors. Everything is new I under there rotors, calipers pads lines etc. To see if it is a hub or the year end I am trying to remove the passenger side half shaft. The bolts holding the shaft are so tight
I cannot break them loose, the best I have been able to do is with the car in gear using a 2 ft breaker bar and extensions together past the body using my whole strength I barely broke loose 3 of the 4. Could this over tightening be part of the problem?
Any ideas?

 

won't be part of the problem, just tight nuts, i use an induction heating coil to heat nuts & bolts to loosen them up, has to be something else causing the tight turning, is the main drive shaft disconnected?

 

In the proses now, have had bilateral cataract surgery so working on the car is on hold i will let you know what i find soon I hope
