installed a ring and pinion acquired from ivan z. - did all of the grinding filing to the housing and reassembled including the wheel bearings shims and caps. backlash and axle play is correct.



i can turn the pinion using the flange and hold the axle so that it won't turn as the pinion is turning. obviously something is wrong. the differentail was fine before i pulled the rear. any clue as to what might be happening?



i used a tool which basically pulled the drum by putting pressure against the axle I hit the sides of the drum with a heavy rubber hammer to cause a vibration to help release the pressure. by pushing the axle in could of I damaged the dirrerentail?

    If you used the standard drum puller (bolt the legs to the face of the drum, tighten the screw by hitting the dogbone with a heavy hammer) you are fine. Banging the outside of the drum with a hammer (I would have used metal not rubber, for better vibration) is also fine.



    Do NOT hit the end of the axle with a hammer! You can damage the block on the inside of the differential

    when turning the pinion and holding one axle the opposite axle should turn if wheel is off the ground. If it don't is when you have a problem. If opposite wheel is on the ground and you hold the other axle and can still turn the pinion is also when you got trouble .

    okay - with both wheels off the ground:



    I held the right axle and turned the pinion and the left side axle turned.

    I held the left axle and turned the pinion and the right side axle turned.

    Then trying to hold both axles so they would not turn I turned the pinion and one axle would always turn.



    if I understand your reply correctly then all is well and I will continue on with the project. If I misunderstood please let me know so I won't do what I will have to undo.



    better to be safe and confirm I'm heading in the right direction.



    thanks!!!
