Just a thought....what about getting it all back on...it's one thing taking a heavy load off the car but when you need to put it back on and line up connections that could be the main difficulty ?

The rear subframe is very flexible on its own, but when you attach the diff to it and then the trailing arms it becomes very rigid. It's one thing letting gravity help you remove the subframe off the pins, but relocating the pins through subframe bushes when the whole subframe is completely assembled, especially the polyurethane bushes, would be extremely difficult.

Took today the subframe down with the diff. No problem there.
However, I took some time to make a decent support on the jack.
The "table" on the jack is bolted onto it to prevent any tilting or sliding.
In addition, I attached a metal bar to hold the jack itself from tilting and falling over. A safety belt is holding the diff on the table.

Some figs here :

The OEM bushes are really very soft :

It is easy to see that those soft bushes allow too much movement and put stress onto the rear bush in the diff and to the floor.

I do not expect any big issues when putting this back with new PU bushes.
I am considering to lift the frame into correct position just the upper part of the bushes in place and then push the lower part of the bushes in place afterwards.. This should make the alignment easier than when trying to lift the whole thing at one go. I think that the PU bushes should slide much easier in place into the subframe compared to rubber bushes. Will test this before reassembly.

Well done!

I used AKG polyurethane subframe bushes and they were a VERY tight fit inside the housings: they needed hammering into place and there's no way they will come out easily. I believe the Ireland Engineering ones can be easily removed. Good luck putting it back.

Seems that the links above in my earlier posts to those individual pictures are not stable for some reason.

So here is a link to the whole album, please scroll down to see the pics related to this rear frame project :

Hopefully this link works better.
