James Duff Radius Arm bushing failed

Post by Unaweep »

Took my younger son out last week to the desert for some fun and just tooling around.
I had to burn off the gas on the smaller tank, it was old. Lot of fun...it amazes me how great the Bronco does off road, especially in twisty situations.

Later at home I noticed the radius bushings looking bad.

I don't know the age of the suspension kit - guessing 80's.

I have had that issue in the past with those exact bushings in the past. The good old rubber ones manage flex a bit better in my opinion. The poly seem to be ok until you start to abuse and flex, where as the rubber seem to manage it better.

I'm not at all surprised the bushings failed, they were really old. They lasted from 198x-2017 vs the original 1969-198x.


and I rather they die on the trail vs just sitting around doing nothing.

drawback of poly. Once a crack starts, it propagates quickly.

Probably a good philosophy for life generally.
