You can follow this if you like.
So first off is checking the ball joint end of the arm. You don't want to go through all of this then realise you've spent time and effort putting powerflex bushes in a knackered arm. I opted to have the car in the air, then using a trolley jack, get the jack so its a little clear of the ball joint, then you can use a pry bar in the space to pry against the ball joint and check for free play.
Once you're satisfied that your arm is ok to use you need to remove the arm to get at the bushes here
this rear through bolt has to be removed
along with the front ball joint
This end is a little easier than usual with the coilovers being on. OEM shocks protrude down through the sleeve much more and mean its a bit trickier getting the balljoint off
You also have to undo the front ARB brackets and pull it down out of the way , then faff about with the steering in cetain posiitons to get access to the bolt, but its not too difficult
Once the arms are off we can inspect them
You can see some evidence of cracking, so i knew they were at least on their way. Interstingly, the arms were stamped 99 as you would kind of expect on a 2000 car, but the bushes were dated 2003, so it looks as if its had some previously
For anyone who's replaced RTAB's on their E36, this will be familiar, to extract the old bush sans press, its easier to hole saw the old bush out
Then you can get a hacksaw in and cut down until you saw through the outer steel sleeve. I had a reciprocating saw which took a little more work out of it for me
With this done, the bush snaps together that tiny distance and it means you can then drift it out easy
Give the arms a good clean then install your new powerflex items using plenty of copper grease so they stay lubed and quiet
Then its a case of reinstalling them along with the supplied washers
The beauty of the powerflex items is you can install them by hand, and you don't have to have the car in its rest posiiton on the ground before tightening the rear bolt
I found a little play in my other front arm on the drivers side, so a pair of these will be ordered next
