I have read about some of you guys installing the poly bushings. I have done a search and can not find out any thing about the differential carrier bushings. The ones on the outer ends of the differential cover that bolt it to the frame. The kit instructions say to remove the factory shell. I have done this. And installed the new bushings.
It occurs to me that this is outside the realm of most do-it-yourselfers. This makes me question if I have done it correctly. I allready had the diff out of the car and the cover off because, I'm installing new yoke bearings and seals. The factory shell is thin aluminum. Without a lathe to make suitable bushings and collars and a decent press, to push them apart, I don't see how this can be done.
Is it possible that many of you guys simply pass on this poly bushing?

I pressed the rubber bushings out and I carefully cut the shells out. However, my shells were steel, the batwing is aluminum. I did not need a lathe and my press is pretty basic so it was a basic backyard mechanic job.
It took some doing to get these bushing out, drilling cutting, prying hammering, but it finally came out. Once the bushing was out getting the metal sleeve out was fairly straightforward. Just use a hammer and a punch / chisel. It would have been much easier to get the bushings out if I had dropped the rear end out of the car but I really didn't want to do that. It was a royal PITA but it wasn't really beyond the realm of the basic DIY job, just be patient.
The small sway bar end link bushings are also a lot of fun.
I used a 1 1/4" thick piece of Delrin. I cut a tapered hole in it, with the inlet the size of the relaxed poly boshing and the other, the diameter of the sway bar end hole. By pressing it through the taper, it popped out, into the sway bar. It worked the same on the link bushing.
I had first tried to put them in with just the press and with the vice. The grease that they supplied, made them so slimmy, there was no way to get them to just push straight in. The grease did however, help with the tapered guide sleeve.

I had the batwing out of the car. I cut through the sleeves with a sharp, triangular file. Others have done it with a hacksaw, etc. It's really no big deal, just takes a bit of time to do it carefully.
I did mine, I wished that I had just left them alone, compared to the rest of the bushing that needed replaced they were in good shape. After I went to the trouble of doing one side I had to do the other.
