Tips on removing trunnion arm at diff end?

[Evan Bottcher]

Can't seem to remove the trunnion arm at the diff end.  I've removed the castellated nut, and I expected everything to just slide off.  The next part on the big bolt just has two big flats, not a hex, and I can't really get a spanner onto it.  Is it threaded onto the big bolt on the diff?

Based on this thread on AlfaBB it seems that the washer part should slide off with some persuasion.  I'll soak it in some WD40 and see how things go.

Yep - they should slide off - they get rubber detritus wedged between them and the shaft making them a pain to get off.  I polish the shaft and grease the sliding nut (maybe I should reword that...   )    to try and keep it from jamming.  As you said - wd40 and use the flats to rotate it with a screwdriver levering it off will release it every time, except when it doesn't

Thanks, that was really helpful.  Came off with a minimum of bludgeoning after a soak in wd40 and a bit of levering and twisting...
