LOGIE Posted January 18, 2014 Share Posted January 18, 2014 Right ive removed the 12 bolts holding the driveshafts on and removed the rear diff bush bolts. I have a trolley jack under the diff to support it. But do I need to have the rear wheels off the ground to actually lower the diff? Or is it safe enough to lower it with the wheels on ramps? Cheers Quote Link to comment Share on other sites More sharing options...
LOGIE Posted January 18, 2014 Author Share Posted January 18, 2014 Ok ive lowered the diff but the driveshafts don’t want to let go. Any hints before hammer time? Quote Link to comment Share on other sites More sharing options...
David P Posted January 18, 2014 Share Posted January 18, 2014 (edited) Separate the driveshafts (with a tap from a hammer if required) before lowering it because they can bind tight with the weight of the diff hanging on them.

LOGIE Posted January 18, 2014 Author Share Posted January 18, 2014 Done that mate the diff is practically hangind/swinging from the driveshafts and all bolts are removed also moved lower arm support brackets. Bigger hammer maybe? Quote Link to comment Share on other sites More sharing options...

Dan_Q Posted February 12, 2014 Share Posted February 12, 2014 Doing some research as i'm gonna attempt to swap my diff soon, and came across this. How easy was it Logie? Any hints or tips, and were there any throw away parts needed for the job? I'll admit I've never done an IRS diff before so doing my homework as best I can. Cheers!

LOGIE Posted February 12, 2014 Author Share Posted February 12, 2014 Easy mate. 1st thing whist the car is on The deck remove the bolts from the rear diff bushes or the ARB will be in the way then jack it up Have the back end up so both wheels are off the ground so that you can turn the wheels which makes getting to the driveshaft bolts a lot easier. Ie rotating so you can get to all of them. Lastly have a good trolley jack or something to support the diff as its heavy esp at an awkward angle. Then remove the actual diff mounting bolts last...the diff will start to lower it may hold onto the driveshafts but a good tap with a hammer loosens them off. Youll be surprised how easy it is mate.

Dan_Q Posted February 12, 2014 Share Posted February 12, 2014 Thanks for the words and the vote of confidence Logie So by the sounds of it, you lowered the diff off its mounts before removing the shafts, is that the same with the prop, or did you remove that in situ?? Good tip on axle stands I was thinking of doing it up on ramps. Might talk myself into making a start on this at weekend. if the roof hasn't been blown off the garage and destroyed my soop that is.

For the record, I changed a DIFF on my driveway and would never do it again - without a ramp and transmission jack its a pain in the ass! With the right equipment, its a piece of piss Quote Link to comment Share on other sites More sharing options...
Al Massey Posted February 13, 2014 Share Posted February 13, 2014 I removed and fitted a diff in a car park. Car on axle stands Removed the drive shaft bolts, quick tap with a rubber mallet will loosen off the drive shafts. Undo diff mounting bolts. Place trolley jack under diff elevated to the diff. Remove the diff bolts, and slowly lower the diff. The drive shafts have a little play and you may need to move the trolley jack and diff forward or sideways to get the drive shafts off properly.

SPG Posted February 13, 2014 Share Posted February 13, 2014 Think you need to remove one side of the subframe brace, as the driveshaft does not clear this, but only on the one side in my experience. Quote Link to comment Share on other sites More sharing options...

I didn't need to do this. UK spec large case diff - I did have to drop the anti roll bar though Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted February 21, 2014 Share Posted February 21, 2014 Agreed its pretty simple removing the diff even on the drive way, gearbox is a PITA though Quote Link to comment Share on other sites More sharing options...
Benjy Posted February 21, 2014 Share Posted February 21, 2014 Did mine on a ramp in literally 15 minutes. So if it take an hour on the deck, you're doing well I'd say. Just make sure you're in the driveshaft bolts properly so you don't round the heads out and that's it. Quote Link to comment Share on other sites More sharing options...
