    Midyear differential crossmember removal

    I'm having trouble removing the crossmember to replace the dried out bushings. Besides the 2 bolts what is holding it in just a compression fit and 50 years of crude? Any tricks to get them to let go? the body is off and the frame is stripped down to this point.

    These things can be an ABSOLUTE BEAR to remove. The only thing retaining them are the 2 through bolts that go through the end cushions. However, when the bolts are removed, the crossmember just does not want to come off. Here's how to do it: install longer bolts on both sides so that the crossmember falls on the bolts and not on the floor when it does release. Then, get a LONG AND STIFF pry bar and wedge it between the frame and the "lip" on the crossmember. Pull down on the bar with everything you've got and keep doing it until the crossmember releases and falls down on the bolts. You will need a LONG AND STIFF pry bar-----at least 4 feet long and preferably longer.

          I used the long bar technique and it worked well but look out when it breaks free. The pry bar gave me a good wack. I had a hydraulic jack under the rear end to catch that.

              Here's my friend Rick with the kind/size of pry bar you need to pop that crossmember loose.
