I have read all the good comments, and took another look at my setup last night. I am waiting on tools, cleaning and painting various bits, so I have plenty of time.
I had to use two channellock pliers, one on each side of the bushing while it was still wet. I cannot turn it now.
The stock bushing has two "arms" which connect the inner and outer tube together. There are two voids in this bushing.
This allows the bushing to give to an extent. Makes the ride better, but the bushing eventually tears. The new bushing is a soft polyurethane, but is solid. W201's have a similar setup.
This is an experiment to see if the lube setup works. I intend to disassemble again at a later date to check on the setup.
The Issue I can see is the center pivot is smaller on the face which contacts the mount. The stock bushing has a large contact face, where the replacement is just a tube. We'll see how it works.
