Diff Removal

[blind_elk]

I'm trying to remove the diff in my R32 GTS4 to replace the pinion mount bushes (seems like a good idea, as the existing bushes basically fell apart!). I did it about 10 years ago, and it seemed to work, but now I can't seem to get the diff to move forward enough to disengage the cradle (rear) mount.

Also, I need to disconnect the ABS sensors, but can't work out how - twist?, pull?, ?

And, while trying to figure all this out, I found a wire and bolt floating above the diff - what did I miss when I last did this?

Well...the wire and the bolt are almost certainly just an earth from the chassis to subframe...follow the wire to confirm.

The ABS sensors have a bit of sealant on them. Twist to break the seal and they will slide out (assuming you also removed the bolt first...)

Otherwise, if the rear mount bolts are undone (possibly hidden behind hicas), the tailshaft and driveshafts are off and the diff front mount is undone that is it. Might just be well stuck to the rear subframe bushes so try a bit of pry bar

Did you detatch the AWD pump from the top of the diff? Because that will throw a spanner in the works if its still bolted onto the top.

Ok, I give up for now. Its like the diff isn't tilting down enough to slide under the pinion mount frame. But I have to get it out now because the existing bushes came out in several pieces, with the shell still stuck in place.

Can someone email me the appropriate page from the manual so I can see how it all fits together. ([email protected])

That was useful. Thanks, diff finally out. Now all I need to do is get the frikken shells out.

This is what came out (+ shells still in pinion bush)

This is what will be going in:

 

I think the necessity of the task speaks for itself.

I would like to replace the bushes that support the rear of the diff. Can it be done by dropping the cradle, but leave the diff in place?

[Duncan]

Yes, but you will also need to press out the rear bushes.....if you have one of those threaded bush presses or can make up something similar

or possibly cut out the old ones if you are careful. The poly style are easier to put back in that standard ones
