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:
