A radius arm Question
My dana 60 on my truck is coil sprinted with factory halfton radius arms. The setup seems to work good except for the bushings. It seems like every couple of months my truck eats a set of bushings on the axle end. They end of splitting in half, or thirds and falling out.
I don't know if this because of the size tires and flex, or what.
Have any of you had this problem?

I ground the inner radius of the C's before welding them up, I may have not ground them enough that's a possibility.
The brand is Moog. They are 0 degrees, cause the arms sit parallel to the ground. Truck probably has around 10" of lift but that's only an estimate. It clears 44s with no rear fender trimming.

Real Big Drop hangers. My pinion is pointed at my transfercase, but I cut the welds for the outer cs and rotated the pinion up so the pinion angle shouldn't have anything to do with it.

I couldn't tell there was a wrong to then on, I think. I'll worry with it more this weekend I guess. If it gets to be a big problem, I may make new radius arms out of DOM and heims.

We had the same issue with Paul's arms and bushings. A minor mis-measurement made the welded on c's too wide and by that point it was too late. So we made some thing shims to go between the front and rear portions of the arms to correct the problem. If you are splitting bushings frequently, then there is a good chance you are having the same issue.

It was pretty simple. Re-measure the width of the welded on c's at both points from front to rear. Then take the empty arms with the bushings installed, and tighten them down and measure there. Add a slight amount for bushing crush, then subtract that from the original measurement from the axle. That's your thickness. Then cut a piece of plate with the needed thickness, drill holes to match the caps, and sandwich it between the caps and arms. After that, you may need to re-drill the lower coil buckets to make the threaded holes line up again, but that should be no big deal.

That's what I was getting at with the measure your c wedge width correctly.
