I need to replace the rear wheel bearings, so "while I am in there" I will also tackle the bushings.
Rubber looks to be the OEM choice but is hard to find with the exception of the elephant racing kit that includes the shafts and install tools. $300+ I used the Elephant bushings on the front. I found poly-graphite to be the least expensive < $20 for a set of 4 bushings only With Delrin as the middle of the road choice. @ $50 for a set of 4 bushings only So what is the +/- of each material? Can you throw a few vendors out there? My car is a daily driver? Clark |

Call a local metal plater like (Google is your friend):
http://www.leonardplatingcompany.com/ Have them prep (remove the rust) and "clear" zinc plate yours. They'll probably be done tomorrow afternoon if you get them there in the morning. Make sure you ask them to remove "all" of the rust before they replate them. Zinc will take over from there and protect them for another 40 years. They don't serve any other purpose than to support the Rebel sleeve (well, that and carry the entire load of the back of the car! (IMG:style_emoticons/default/biggrin.gif) ) so, I'd say that a minimal amount of pitting on the old bushing surface shouldn't affect the load rating at all. I'm "guessing" that Rebel wants you to JB that sleeve onto the shafts. Those old pits may serve some purpose in retaining some of the epoxy. We do a lot of Elephant installs and we'd send our pitted shafts to McMark for his roller bearing installs. His design used a bearing race much like the Rebel product sleeve but, they machined the pitted ends down on the rods and glued their races on there. It made for a very precise fit. That's the piece (the precision fit) that all of these bearing/bushing systems have to overcome. They all do it in slightly different ways. |
