WahooSteeler Posted September 17, 2018 Share Posted September 17, 2018 Need to replace the tired worn out bushings on the front end components soon. Opinions on rubber vs polyurethane? Seems like polyurethane would make rough roads, potholes, railroad track crossings etc that much jarring. Link to comment Share on other sites More sharing options...
dvitha Posted September 17, 2018 Share Posted September 17, 2018 Here at the shop we like to rubber if possible. polyurethane is much stiffer but has longer life between changes. However I always recommend rubber bushings my self in the shop for anything driving on the road. Link to comment Share on other sites More sharing options...
Pete M Posted September 17, 2018 Share Posted September 17, 2018 my only experience with poly is the C-bushings on my ford 44 and they were sooooo stiff Link to comment Share on other sites More sharing options...
Pete M Posted September 17, 2018 Share Posted September 17, 2018 if you're talking about the control arms, now is a good time to contemplate WJ arms. Link to comment Share on other sites More sharing options...
WahooSteeler Posted September 17, 2018 Author Share Posted September 17, 2018 Pete, I put WJ lower arms on earlier this summer, huge difference, still have uppers to put on. I'm talking about any other bushings on the front end involving steering or suspension. Link to comment Share on other sites More sharing options...
HOrnbrod Posted September 17, 2018 Share Posted September 17, 2018 I use poly bushings for the front and rear sway bars; seems to stiffen them up a bit. But everything else is rubber. Link to comment Share on other sites More sharing options...
johnj92131 Posted September 17, 2018 Share Posted September 17, 2018 Someone correct me if I am wrong. But doesn't the term "durometer" describe the harshness or softness of any bushing? So a .75 rating should be the same across different bushing materials? True or not? A .75 urathane bushing should be no more or less harsh than a .75 rubber bushing?

Gjeep Posted September 17, 2018 Share Posted September 17, 2018 I like polygraphite as it doesn't squeak and you can opt to buy greasable. Any Energy bushings that are black are polygraphite. I've been running them on my '01 XJ since new front and rear sway bars and not a squeak. Link to comment Share on other sites More sharing options...

I don't know squat about durometers John, but THIS is an excellent article detailing the characteristics of suspension bushings. You ever try the poly Brown Dog motor mounts? Never again - vibration maximus. Link to comment Share on other sites More sharing options...
