4107 Radius Rods and Bushings

[gus]

Arthur,

Those short bolts may be the reason my supplier is sending studs, they can be longer than bolts and still allow drawing up the washer on the bushing without a longer bolt to get the bolts started.

The only reason I can see for bolts is to prevent mechanics from tightening the bushings too much. Bolts will bottom out in the threaded bushing pin before they compress the bushing too much.

One other thought, the bus has to be level and all suspension height distances correct before the bushing bolts/studs are completely tightened to prevent preloading the bushings in the wrong position. This would surely shorten the life of the bushings.

While you are going through all that work, don't forget the ones in the back.  They can make a tremendous difference in handling.

Len,

The rear right lower rod is the one I'm repairing.
