How to replace inner bushings of rear upper/lower control arms?

So, one day I went out and found my driver's side rear tire was completely flat. I decided to replaced it with spare and think 'wth happened?' later.

Anddd..didn't take too much time to figure out why.


Obviously excessive camber wear must've overstressed the tire, eventually made it torn.

So, thanks to numbers of DIYs and edzgarage on youtube, I was able to figure out how to replace outer bushings of upper(#2)/lower(#3) control arms and RTAB(#4).
BUT the problem is the INNER bushings..#6 and #14


I wasn't able to find any DIY for replacing those bushes, not even an information of what tools would I need for that specific job. Of course I could just buy new upper/lower control arms with pre-installed bushings, but $600 vs $60? What would you choose???

Does anyone know how to replace those bushes? Or what kind of tools would I need? Well edzgarage's video showed this tool;
http://www.ebay.com/itm/BMW-Rear-Axl..._Tools&vxp=mtr
Would this kit capable of removing/installing inner bushes as well?

I have very limited knowledge of this sort of tools and don't have much experience on rear suspension jobs, I may rely on your advice a lot.
Thanks a million!

you just unbolt the mount and press it out and push a new one in?
search RTAB DIY.

OP, having done this job before, you understand you have to remove the rear diff to replace these bushings, right?

You will need Baum tool #B333351 to do this job.

You don't have to remove diff to replace the bushings. The bolt is pretty long and you'll have to play around with it to get it to drop, but you can do it w/o dropping diff

To replace bushing #14 in the above illustration, you have to drop the diff.

The top bushing is a simple press out / press in deal. Be sure that you get them going in the correct way! One end is longer and (from memory) it goes towards the front.

I don't know why you'd replace the lower bushing. Just buy new arms, those things bend like butter so chances are yours are a little tweaked anyway.
