Rear suspension bolt rusted in / bearing replacement question
 

My uprights are rusted solid to the bolt that holds them into the lower control arm. I'd really like to focus on the swap and deal with that issue later. Big brakes and urethane bushings would be a nice winter project next year. Anyway I popped my hubs out and sent them to Martin.

My questions are:
Can I pull the subframe to weld in the diff hanger without pulling the uprights?
Can I put my hubs back in and the axles with the uprights stuck on the car?

The oil you see is many blasts of PB blaster not the bearing leaking. I was planning on replacing bearings but don't think I want to try that with the stuck uprights.

Thanks guys!

WOW! a lot of spam ads on this forum lately as posts....
to the question posted, you "could" do it that way but I would work on that hrough bolt instead. If you heat the center section with a MAPP gas torch and get the bolt red hot, it should free up and come loose. Make up a heat shield for the bushing to keep them from going up in flames, but if you are doing an upgrade soon anyway....now might be the time. I have had good luck with this in the past. Be sure to coat everything with anti-seize when you reassemble....too much is just barely enough
