has anybody put in OEM trailing arm bushes, themselves?

I have just bought some from BMW and they are split along the outer liner and they look like they need a good deal of compression before they will go into the bore in the trailing arm -how does one do this? is there a tool to compress them before they get pulled in?

Haven't done it myself (had independant shop install), but if you are replacing them, get the ground control.

Here is a b-world link, but you can find them all over. My shop had them in stock.<p><p><p>2002 topaz M3 convertible

and replaced with Powerflex bushings. Yes, you need a special tool to both remove the old ones, and to install the new ones. Although installing is much easier than removing. You should actually be able to pretty easily install with a long bolt, nut, some large washers, and a couple of correct size bearing/race disks, or large sockets turned backwards... i.e., one larger than the trailing arm hole to "pull against", and one a little smaller than the bushing to pull the bushing into the trailing arm. Use lots of bushing lube.

The actual BMW tool consists of a large cylinder that rests against the outer edge of the trailing arm hole that holds the bushing, and has a disk just smaller than the bushing on a long bolt. You tighten the nut on the bolt, which moves the disk, which drives the bushing into the cylinder. You reverse it all to install. The tool costs around $500, but you can rent it for around $100.

I would suggest Powerflex, or some other aftermarket bushing because they both reduce flex, and are easy to install and remove because they are multi-piece and do not have to be pressed in and out.
