Background:
My Polybush brand (front bushing for the rear radius arm) was only 2 years old when it completely disintegrated when off-roading last year. I used the orange colored one (Medium Duty)
I could not get the same orange colored bushings last year due to COVID supply shortages. I ended up replacing them with the blue ones (medium comfort). Well, one year later, the bushing disintegrated on an offroad trip. I am guessing the Medium Comfort rating is not adequate for our type of off-roading (lots of rocky terrain).
The Polybush brand as a red version (performance racing, Hardest elastomer rating of their bushing levels).
1) Can I get thoughts on poly bushes in general? Polybush's site claims they they last longer than the factory rubber ones and are easier to change. However, two failures in just a year is strange. Their two piece design would be easier to replace. What has been your experience?
2) What about the elastomer hardness selection? Wondering if I should do the hardest (red) version instead of the medium (orange)?
Thanks in advance.
P/S. This was my buddy’s bush fix idea to get me out of the trail. The material was tough to scrap off. Luckily he had a small butane torch to burn off the remaining polyurethane material. We used a heater hose wrapped around the pivot bushing to cushion of the metal to metal clunking.
