Default Differential/cross member removal

I have trying to remove the differential/cross member on my '70, but I can only lower it about 1/2". Everything is unbolted except the pinion mount for safety.

Thanks!

Here's how I did it and if you search the forum you can see other approaches.

Squirt copious amounts of WD40 around rubber bushing the night before.

Loosen cross member bolts to allow about 1/2 inch of vertical travel-just like you have started.



Leverage the pry bar to pop each side loose. Several attempts required, but very obvious when it breaks free.

Default Crossmember Removal

I hate using a crowbar on any part of my vette. Just me

I found that using 2 jaw puller works like a charm

I found some old bolts the correct thread and drilled a hole in the center of the head to prevent the puller from slipping off the bolt. They were longer than the originals too so that I knew the crossmember would completely dislodge once it popped. It WILL POP when it breaks loose

I third the gear puller. More elegant than the other methods.

Just recently did this with the puller as well. Soaked the rubber in PB and Kroil for a good 4 days before trying though. Took some wrenching on the puller but eventually popped out.

5x on the puller

Use the biggest jaw puller you can find, and that thing will pop right off. The reason you hear horror stories about how hard you have to pry on it with a crowbar is because that method only puts pressure on one side at a time hence the bushing binds up hard.

btw, i got my puller off ebay for around $15, well worth it. It was an older craftsman. 1 thing that seemed shady while using the puller is that where the 2 arms were pulling down on the crossmember, there was no teeth to make sure they dont slip off. The feet of the puller were only "hooked" on the crossmember for around 1/4". Very carefully though it worked without slipping.
