Rear Subframe Mount Replacement
 

Can anyone comment on the difficulty/time replacing rear subframe mounts? In Bentley's Manual, it looks quite difficult, especially w/o a lift and only one person. In pic below, what I'd like to replace is item #2, i.e. p/n 33 31 6 770 454. Thanks!

Still Need Help on this subject! Thanks!!

I did this job earlier this year, on my own, on my driveway. Not too hard but you do need to buy / rent the tool for pulling the old bushes out and pressing the new ones in. You also need oxyacetylene or a good blowtorch so that you can bend the exhaust hanger out of the way.

If you're fairly mechanically competent allow half a day the first time you do it. You can probably do it in half the time next time around.

Thanks Sundayjumper! What type of tools? Do I need anything special to support subframe? Thanks.

Trolley jack & axle stands - obviously - and I think a pry bar and maybe some bits of wood got used too. I'm afraid I can't remember exactly. Usual socket set of course. The special bush tool is like this:

and the powerflex bushes that are used in the how to are very good, I have had them fitted now for 2 years and no problems.

If you don't have access to the special tool for removing the old bushing, and are ready to sweat a little bit, you can destroy the old bushing by drilling multiple holes in the rubber all around it, then remove the center section. All is left is the outer sleeve of the bushing. I use a air chisel (zip gun) to deform that sleeve the most I can, then zip gun it out of the subframe. It works everytime, but it's a less elegant method. The Powerflex should go in with a minimum of effort. At the worst, use a threaded rod with washers and nuts and a mixture of dish soap/water (that will evaporate later).
