RR trailing arm bushing question

[Compact95]

I'm getting ready to refresh all the rubber parts on RR susp of my 95 318ti Club Sport. Regarding trailing arm bushings, I'm a little confused about realOEM listing here
http://www.realoem.com/bmw/showparts...99&hg=33&fg=30

It implies that there are two types of bushings:
33329061945 is "SET RUBBER MOUNTING" with qty = 2
33329058822 is "SET RUBBER MOUNTING ECCENTRIC" with qty = 2

Is this right? Two "normal" and two "eccentric"? Or all four of one type?

Only reason I ask is because I get some wierd/conflicting results when searching various parts web sites (Pelican Parts, for example).

Anybody know?

When you order one you will get both bushings to do one trailing arm. So two sets will do both sides.

The eccentric bushings are offered to correct alignment if someone slightly bent a trailing arm. They can also be used to provide a custom alignment in the rear, however, from members experience on here, the eccentric bushings will "lose" their alignment after a while.

Aside from going to a full DTM subframe setup, most people recommend welding in adjustment tabs if you want adjustable rear alignment.

FWIW, I stuck with stock, non eccentric trailing arm bushings when I did mine.

Excellent! Thanks for clarifying. I ordered two non-eccentric bushing sets today and should be all set.

When you get it compiled, would you mind posting your parts list here? Would be a great reference for others who may do this in the future.

How difficult is this repair? I already have mine on hand, just waiting for the time to come to do it. Is there a DYI post around here? any special tools required?

Trailing arm bushings are fairly straightforward but involve taking apart a lot of the rear suspension. I disconnected the rear brake lines, unbolted the axles from the diff, rear shocks, swaybar endlinks, parking brake cables (at the handle), sensors, and then took out the bolts for the trailing arms. You'll need to make or buy a tool to push/pull the bushings out.

AKG motorsport sells a tool for $35, I chose to make one using all thread. I used a heat gun to get the bushings nice and hot, it made pushing them out much easier.

CirrusSR22 has a good thread about it.

I referenced that thread when I did my rear suspension refresh. One thing I can tell you is that I tried pushing the bushing out with all-thread, but I was afraid I was going to bend the trailing arms. I ended up cutting the flange of the bushing off with a hack saw, then used a press to push them out.

Long story short, be carefull getting the bushings out.
I think it will be worth getting the tool from AKG. The part no. is #RTABTL.

In hindsight, I would have also gone for the AKG tool. Heating the bushings up until they were greasy worked though, they slid right out.
