Default differential crossmemeber bushing removal

How do I remove them so I can clean and powdercoat the crossmember? Should I try to reuse the bushings or get a new set? Thanks.

I think they are about $90 each. If yours are in good shape, you may want to leave them alone and just paint the cross member.

I never tried to take mine out. When I sand blasted the cross member, the bushings looked good so I masked them off and painted.

the crossmember is removeable. take out bolt thru each rubber cup. sometimes a real job to remove because of age, suction, etc. others come off easy. pry down on each end, might pop off. good luck.

I think he already has the cross member out. The question is can he remove the bushings without distroying them? I never tried so maybe someone with more experience the me can jump in.

If you remove the bushings I would replace with new ones. You have to bend the tabs to remove. Bending them back will make them weaker.

Yes, I already removed the crossmember. I used a gear puller that I borrowed from Auto Zone. It worked great. Thanks for the forum search.

Are these the tabs you're refering to? Once I bend the tabs back, does the bushing just fall out or do I need to use a hammer or a gear puller to get it out? Thanks.

i did this job a few months ago. Bend the tabs up and get a large socket, prop the crossmember up off the floor with a 4x4 and hit the socket with a sledgeto drive the bushing out. use so wd40 to help the process. this worked for me and i didnt damage the crossmember or the original bushing. my original bushings were ok (rubber still flexible) but i decided to replace them. the trick with this method is to apply even force across the bushing as you are hitting the socket so that you dont canter it. good luck. it will look great. also, you may want to consider the support kit that most of the vendors sell for $35 (i think) - its a large alminum disc that supports the bushing.

Default 72 Bushings

When I restored my 72, I removed them with a hydraulic press.
If I remember correctly, it took almost 25 tons of pressure to pop them out. I put new ones on, anyway and used never seize in the cups.

Guess I can go get a haircut now. The bushing came out pretty easily. I used a 3 jaw puller and they came out in a few minutes.

Thanks for all the help, guys.
