Bushing Tool Diameters for Full Rear Suspension

I'm about to pull the whole rear suspension to repair the tears in my subframe mount points. The only thing holding me back is getting all the bushing removal/install tools in place.

I see that in this thread was looking for specific info (but not with much luck).

I would like to know the diameters of the tools I need to remove and install each of the bushings. Then I can see if there is something in my tool kit or I have to find them.

The bushings are identified in that thread, but I have included the pictures here:





I also want to replace the four subframe bushings (2 x 33316770781, 33316770783. and 33316770784), so info on that would be helpful.

I haven't bought the bushings yet, so I can't measure them.

Why not buy a universal bushing extraction set:
http://www.ebay.co.uk/itm/Universal-...item5d3ff128ee

I did my complete rear axle with it and it maybe took me 3 hours to remove all bushings once I had the rear axle assembly off the car (so about 15min per bushing).

For some bushings you may need a socket or some steel rings to fill some spaces but you should be fine.
Bushing #7 (rear diff) is a bit tricky because space is tight, for the subframe bushings you need to heat the subframe (just warm it up with a gas burner, it just needs to be warm to soften the rubber coating on the bushings so they slide off more easily. You want them to slide out as easily as possible because you cant place the bushing extractors very straight on the subframe).

With the universal set you can also get the #4 bushings out instead of grinding them.....

For the front diff bushings you may need a socket as inner press (they're fairly small).

A nice oppertunity to replace all bushings with polyurethane versions
Bushing #10 and 13 you can get in poly at strongflex (both shore80a and 90a), as for some other bushings (subframe, rtab, but powerflex has them too in a slightly better quality for a slightly higher price).
For #3 you can use another ball joint #2
Poly Diff bushings you can get at akg motorsports (only shore95a and harder), or if you want a softer rear diff bushing, you can get a shore80a on the uk ebay from a company called P.S.B.

That's perfect, Guido. I just need to find one that can be shipped to California. I have not seen a complete kit like that, but now that I know what I'm looking for, I expect it will turn up soon.

Thanks.

If the german ebay has sellers for about 150usd and the UK ebay has sellers for about 150usd, ebay.com probably has them too

This is the cheapest I could find in a few sec, but the shipping makes it expensive (but these kits are heavy, 50lbs or so)
http://www.ebay.com/itm/Universal-Pr...-/331019201235

or this one (with less parts (not the big 90mm sleeves but with some end caps)):
http://www.ebay.com/itm/26-Pc-Bearin...-/231050556324

Or this set on german ebay:
http://www.ebay.de/itm/Silentlager-W...-/230996874561
153 euro inc p&p to the US (so that's about 207USD)
