Those are the Subframe mounts. Its possible to DIY, but its a lot of work. Google it and there should be quite a few writeups on it.

The E30 manual found here does have the steps. I just will have to remember NO BEIR!

D. Clay did his himself, and has some insightful (and funny) insights here. Depending how things are going under your car, it can be a major ass pain.

I have put off doing mine, and put off doing mine... you get the idea.

There's some fun stuff you can deal with when the subframe is off:

- trailing arm bushings
- reseal your diff + new speedo sensor
- stainless steel (or new) rear brake lines
- check your e-brake setup
- muffler!
- rear springs, shocks, and shock mounts
- rear swaybar mounts, tabs etc.

etc etc etc... it never ends...

It's a royal PITA, usually because once you have the subframe dropped (which is a challenge in itself, especially without a lift & tranny jack) you will likely find a good chunk of the old bushing material and metal bits up in the housing it seats into (affixed to the body of the car).. or wraped around the subframe bolt.

The rear subframe bolt goes in through under the back seat of the car.  It's hard to find and remove these and get rid of all that old material.  Best way to do this is to probably bang out the old subframe bolts (long bolts) from below, and hope all the remaining material will come out below.  

Install new bolts and washers, press in new bushings, and replace the rear subframe nuts (this is important) that thread on from below.

So, from that Real OEM diagram, you'll probably want to also replace #12, 2, 7, and I highly reccomend replacing 5 & 6 as they are cheap.  

As Febi explained, when the subframe is out, this is the right time to replace the trailing arm bushings and bolts.  I reccomend the factory rubber eccentric bushings with new bolts, but there are lots of options.  #9 in the diagram is the trailing arm bushing.

Hopefully mine will come out easier this time as the bushings were just installed.  I need to reposition my bushings on the rear subframe.  Make sure yours are pushed in all the way.  I reccomend taking some pictures of what the whole thing looks like before you start so you have a reference when putting it back together.  

I want my own shop and lift!  :rolleyes:

Thanks M42.  The shop is set up for this Saturday at 7am. I need to double check my shopping list.

If you need the eccentric TA bushings and bolts ASAP, I can send you mine if you replace them later.  You can rush deliver the bushings from Bav Autosport, but I can probably send them to you cheaper.

Okay, I'll bring them by the office tomorrow in case you need them, I can send them out.  I just want to get the same thing back eventually as I'm going to pull the rear end out of my parts car and build it up and ready for my next E30.  ;)

FL318is...   I just looked through my stockpile of parts.  Unfortunately I only have one pair of the eccentric bushings, so you can only do one side.  I need to order another pair.  

So, Unfortunately, I don't think I'll be much help in your situation.  Sorry, I must have messed up when I placed the order.  :(

If you call Bav Autosport, they should be able to 2nd day deliver them.  The dealer will be able to get you the nuts and bolts you need in 2-3 days.  Order your stuff tomorrow!!!

Did you get all the parts you needed off RealOEM?  

Well, bring your digital camera and take notes on the process for all of us (especially on re-installation of the rear subframe and the rear wheel bearings).  You can post it in the DIY section.  

You may want to re-tap the bolt holes in your diff when you have it out.  I did that, and made re-mounting it to the rear subframe much easier.  

Good luck, and may the schwartz be with you (Diamondschwarz that is!) :D

LOL  Yeah we start tonight.  Hoping the thunderstorms are done by then. Little scary with the garage doors open and seeing those lightning bolts.  We got the TA's thru a local import supply (Triangle AutoParts).  Real gear heads and they are poly.   I agree the re-tap is great.  So far we have been doing that on everything.  It is amazing how clean and easy it makews redo.  I will try to take pics but time is of the essence.

Maybe we should all chip in and start a DIY garage, LOL!  Would love to have ya'll heppin' me!
