ihckb2 Posted August 23, 2014 Share Posted August 23, 2014 Most of your auto supply, hot rod parts stores carry Energy Suspension. I switch all my bushings over to these and they are great. Link to comment Share on other sites More sharing options...
Blindcars Posted August 23, 2014 Author Share Posted August 23, 2014 The hard part is finding "non standard" bushings like the ones on our rear diff mount :(the ones on my prior chassis is a totally different size than my new chassis), hence the reason i was going to have my machinist friend machine me some. However, turning Duro 85 polyurethane is proving to be a challenge as it wants to deform when machining. With the listed dimensions on the link i posted i should be able to source a "factory" made poly bushing. By knowing the dimensions ( where the link comes into play ), i can figure out energy suspensions part number for the bushing i need. Also i dont have to buy a "kit", i can buy just one bushing if so needed . Link to comment Share on other sites More sharing options...
ihckb2 Posted August 23, 2014 Share Posted August 23, 2014 You can sand the poly bushings with gentle pressure and about 100 grit. You might have to make up some jigs to support the bushing. I placed the bushing in the sleeve while sanding. I used my 10" radial arm saw with sanding disc. I was able to trim down the outer diameter of the insert as well as the outer diameter and thickness of the head. make your sand cuts very shallow and rotate the bushing by hand. there is a bit of trial and error on getting the proper diameter as when you push the bushing on the sleeve it expands slightly so do checks as you go with the sleeve removed. I used a tight fit into the boss using silicone spray as a lubricant then installed the steel sleeve. I used silicone grease as a lubricant. They don't squeak and they have been in 3 years.
