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?
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.
