I did the PB soak, jaw puller, time method. But I also used a little known automotive tool called a cinder block. Ratchet strapped it to the crossmember and let it free hang. I think it was the cinder block that broke the crossmembers back....

Yep. Worked on one side. Hanging from the passenger side as we speak!

Great!
Now DO NOT pull down on the loose side.
Stuff will easily bend with all that leverage! BTDT

Agreed. In fact I was already concerned about that issue so the diff has some slight upward pressure on it from my motorcycle jack and wood blocks...which are ready to catch it when it falls. I been at it every few hours with some more PB and a couple turns of the 3 jaw puller bolt...which is now getting close to slipping off the crossmember bolt. Still no love. Gonna let it sleep on it to see if it gets convinced. Otherwise..the beatings will continue until morale improves.

Soaked with WD40 and ordered a (cheap) puller from Amazon. Let’s hope the cheap puller doesn’t explode on me

Day two of WD40 and Amazon delivered the below. It looks too flimsy to do the job - but maybe in combination with a pry bar and BFH



Looks wide enough.


Is big enough - if flimsy looking. 22:05 here. Too late to do anything.

I got a large 3 jaw puller from O'Reilly Auto Parts. One jaw was tricky wedging in. Got that set up...hung the cinder block. Kept hitting with PB and a couple turns on the puller. After a couple days I put a pry bar in and that got it to pop. Amazing how frozen these things get.

Rust swells a lot when it forms. In this case it swells INTO the rubber and just gets tighter and tighter!

And this old rubber is tough! Some of the stiffest rubber I have ever run into. Good thing it's not a tire. It could imitate a hockey puck!

Success



Pop !!!! Always scary AF. Especially with these cheap pullers. Well spent.


Off it comes. Heavier than I thought.


Rubber is in very good shape. Keepers.
