Working on my long-dormant 89LS project. The trailing arm bushings are toast, and the front part of the arm itself is beat to hell from making contact with the frame mount (due to lack of good bushing!)

I have Gen2 arms I acquired way back here on the forum and also bought new bushings. It's time to swap them out. FSM calls for 2 tools: MB991293 and MB990891.

I can only find the later online. The former - not a thing.

1) Does anyone have these tools?
2) the FSM diagram on tool placement doesn't make any sense to how I would think the bushings need to be pushed out and pushed back in. It appears as though the FSM is trying to get you to squeeze the bushing together? Odd. Same on my 89 FSM and the 92-95 (Gen2) FSM I seen.

If you guys haven't used the special tools, what did you use> I've heard of guys burning out the main rubber and pressing out whats left. Sounds messy, and unnecessary. A large socket sounds dangerous. Removal is puzzling since the outer bushing ring lip is so small. installation seems a bit easier since all I think you would need is a flat plate with a hole to accommodate the center bolt sleeve.

Search going back awhile only revealed discussions on part numbers and interchangeability.

Looking for insight on bushing change procedure itself
