I snapped a driveshaft on my rally car recently, and had to finish the stage with 1 wheel drive, as a result the diff s**t itself.
Now the problem i have is that the driveshaft cup (rest of the shaft is removed) is stuck in the box. I think the splines on the shaft are well chewed up.
Any suggestions on getting this shaft out? its a tricky one as prying and levering isnt really an option as i dont want to crack the casing. I have tried welding onto the driveshaft cup and slide-hammering but no avail.
I know there is a little clip on the end of the shaft splines but surely it cant be this strong.

Cheers

Have you tried a slide hammer? Usually works after only a couple of taps!

I had to weld a bit of metal over the front of it, with a nut welded on and then used a slide hammer to pull it off...

Thanks for the replies, i will try with a big punch (if i can get it through from the other side)
failing that i will try the slide hammer method again, did pull like feck on it last night but might just need to give it a harder pull..

Best way is to drop the diff pan turn the diff so both shafts are exposed the pry them from insife at the end of the shaft.
Never fails.

A couple of taps with a slide hammer will sort you right out and not risk any damage to the gearbox or driveshaft seal. Great addition to your toolbox for removing other stubborn items as well.

Its a quaife diff, so not sure if the ends are exposed enough to pry on. I think its stuck in further than that.

Have tried the slide hammer method, wont even shift it though. Must be well stuck. My slide hammer is huge too, this is the first thing its never worked on! Il try again though as i cant see any other way at this time other than sticking a grinder in there and sacrificing the diff, which appears to be cracked anyway.
