I replaced the radius arm bushings on my truck about a year and a half ago and about 6 months later I found that the nylon spacer on the driver's side cracked in half and only half remained on the truck so I replaced it (under warranty) and I found the same thing again today. I torqued it to factory specs and the passenger's side is fine. What gives?

 

Keep us informed on what happens. I just finished replacing all of my suspension bushings with the Energy Suspension Polyurethane ones. I will be keeping my eye on them now.

 

Mine are Moog radius arm bushings and Energy Suspension axle pivot bushings. I wanted a little softer feel on the radius arms and a more resistant pivot bushing but it looks like one of the pivot bushings is worn out already anyway.

 

Oh how wonderful, I am looking into getting axle pivot bushings and leaf spring bushings from Energy Suspension and radius arm bushings from Moog. ... I sure hope its just a fluke with your bushings wearing out prematurely... that would tick me off spending all that money and then have them fall apart.

 

I'm also running both Prothane & Energy Suspension bushings in my E250's and not a single issue with either so far---been in excess of 70K miles too.

I never knew hard nylon was used for suspension parts. The urethane formula for radius arm and axle pivot bushings is hard enough of its application, better than the stock offerings.
