Title: 4106 Suspension Bushing Replacement
Post by: Darkspeed on June 30, 2015, 10:59:31 AM
How difficult is it to replace the suspension bushings  in a 4106?

Should I use OEM rubber or poly? Energy Suspension poly?

Lubrication? Drill and add Zerk fittings?

Any tips?

Thank You!

Easy to replace.  Cut the old ones out, remove built up scale and rust inside the hole, and press in the new ones.  I was able to use my hands to press them in when I got the holes clean enough.  Some have used soapy water on the bushing to help it.  Just remember to have the coach on the ground when you tighten up the plates.

There are no grease fittings.  I used the rubber style, I got them from Luke.

The bushings flex as the suspension travels up and down.  The side plates sandwich the bushing, compressing the sides a considerable amount. The ideal setup is that the bushing is relaxed (not twisted) when the bus is at it's normal ride height.  Over time, though, I would think that the bushing will find it's happy place in relations to the ride height of the bus.
