sierra rear end
dave r - 16/5/13 at 04:27 PM

given enough height, is it possible to remove a sierra diff from its rear subframe/tube, without pulling a driveshaft/ wheel bearing carrier ?

want to do it indoors, but the garage is a bit tight....

yes, the whole rear beam comes off in one:



the long bolts at the front/sides of the beam can be a pain (the ones that go thought the big rubber mounts)
other than them its just the propshaft, diff mount, dampers and brake lines/cables

if your going to lift it up high to do the job don't forget to use something to catch the beam - its heavy !!!


mind you I cheated a bit with that one

Bolt on or push-in driveshafts?

I think with bolt on, it should be possible.

I removed the whole subframe (as above) although I didn't have a tractor so it was a bit more scary towards the end.

push in shafts, hoping to get diff out of car/beam without taking the hubs off.....

If you were just after the diff.....
I cut one out with a 12" grinder

I did my first one without the tractor - lifted the car just enough to work on it then dropped the rear beam onto big wooden blocks so that it only fell about 3" so no damage to the chassis or diff/beam

the bolts that hold the diff to the beam and driveshafts to the diff are the biggest problem - they are always rotten and can be a real pig to get out
(much easier job with the beam off the car)
