Hello all,
This weekend I was attempting to pull the axles from my 1978 8.5" GM posi rear end and could not get the cross pin (crosspin) out (the big one in the spider gears) from the center of the diff.
It would only come out of its spot just past where the retainer bolt hole was almost fully visible. It isn't seized in the posi....I think the spider gear, or gears, are causing the issue.
We beat on it with a big hammer and big drift for quite a while....no luck.
The rear end has been apart twice before (once when bought to put in 4.10s, and a little later to fix that shoddy job with the 4.10s in it now). But, it has been 10 years now since it's been apart.
I wonder if the crosspin is bent, or if it is galled badly due to drag racing....I can't find many examples on the internet, except for breaking the retainer bolt (which did happen).
Anyone have experience with this? I don't "need" to spend a gazillion dollars for a new rear end.
It has held up to a ton of abuse. I just want ideas, or similar experiences from those that were able to fix it.
Thanks
Clark
