In-car replacement for trailing arm bushings
I have my eye on some Elephant racing monoballs for the rear trailing arms (where they mount to the torsion carrier) but don't want to go through the hassle of pulling the arms off the car until I'm reading to do a full refresh. Anyone have a good method for driving out the steel races for those bushings? I have all sorts of tools, but not a welding setup.
My main concern is dropping the forward half of each arm low enough to clear the mounting brackets, since the arms will still be bolted up to the spring plates. I can do the whole cutting/pounding thing if there's proper clearance but I don't see much in the way of first-hand experience. The last thing I want to do is **** up the old bushings and then not be able to complete the job without pulling the arms - if this is simply a bad idea I'll just wait until a complete refresh is in the cards.

Unless you were trying to 'fix' one broken part it makes no sense to upgrade this.
it would be devilishly hard with most of the rear intact.
It is VERY easy to damage the aluminum trailing arms during removal.
Save up. Buy all the bushings you want to replace, then drop the torsion carrier and do all at once.
With it out its not that bad.
I did it once in a driveway on jack stands.
And another time in a warm garage.

I just did this, and would suggest pulling the arms, it's not so bad. I can't imagine burning the old bushings out right next to the gas tank...

All I can tell you is that the Elephant Racing "Split Bushing Removal Tool" will *not* work. I emailed them about it and they said it's not the right size for the rear bushings

Ok, I'll just be waiting until I have a reason to drop the whole assembly. I have rear wheel bearings to do as well, but I'm really trying to avoid big projects on this car until I make more headway on the 951. Thanks for the input, everyone.
If the bushings are original 1983 rubber, you're implying that there's no improvement to be had? This is just a street car, but maintaining good alignment during cornering is always a plus. The NVH would be a non-issue due to the mounts between the torsion bar assembly and the chassis.
I saw that tool on their site the other day....figured that, since they specifically stated which bushings it was applicable to. I wonder if anyone makes a more universal/less expensive version of this tool. It looks like it costs $3 to make.

I didn't catch if this was an early or late model, but rear wheel bearings in steel trailing arms are not a bad job at all. Just make sure you have some big a** sockets and a cheater bar to match.

VW part sources were great, even the bearings and hardware are the same. I ended up getting a ton of stuff for refreshing the rear end from them, for really cheap.

Funny you mention that, I actually just got the last of the parts I need for this job 20 minutes ago in the mail. Steel arms. I got this tool, which from what I read on VW boards, makes removing the axle nuts really easy:

I was also told the tool is only meant to be used with the arms "on the car" for 911s.

I can also verify the tool doesn't work on the split front bushings either, at least it didn't for me. Even after I took it to a shop and we tried using it in a press, it didn't work and we eventually tore the "teeth" or whatever you call them, off the tool.
