E39 rear lower bushes

Located in the rear lower control arms, jack up the car and check for play top to bottom in/out movement on the wheel, I had quite a bit of play at the bottom, seems the local parts supplier GSF Daventry sell loads of bushes for these cars although it's technically a ball joint it looks like a bush, The removal of the old one was an absolute nightmare, first remove the retaining clip (snap ring) we heated it up, we tried knocking it through, we made up a puller, took ages to get this thing out! at one time it was considered to remove the entire hub and work on it off the car but even that's a job in itself. eventually got it out with heat muscle, patience and a puller, fitting the new one was a lot easier after a cleanup with a dremmel. the problem seems to be a combination of the thing was pressed in with a ridiculous amount of force in the first place and the usual reaction between steel and aluminium.

If you are not brave or equipped with a gas torch and puller, don't even attempt getting this out, you'll be far better off getting a local garage to do it. I will next time!

I did mine but I took the time to make a press to press the old ones out. I used huge sockets, threaded stock and nuts that I borrowed from a friend to press the old ones out. I put my new ones in the freezer overnight so they would contract a bit and used sockets with threaded stock, washers and nuts to press the new ones in. It was a Bitch but i did both in about 4 hours in my garage. There is a tool/press you can buy but it costs about $300. Go to this link. It outlines the job so you can prepare for everything like I did.
