How much trouble is replacing leaf spring bushings?
Will I need a press?
Also who makes good bushings?

Press no a torch yes. Melt out the old bushings then new bushings should come with a lube and they slide right in. Energy suspension make leaf spring bushings. You can get them at summit or even you local parts store will have them they should also have replacement bushings if you want to save

If so I can't hear it over my Flowmasters.
I know 20+ years ago when people started to run the polyurethane bushings on street cars the squeaking was a problem, I think they fixed that problem.

Say I just want to replace with rubber bushings are they going to be more trouble than the poly.
Does anyone know if Moog sales rubber leaf spring bushings.

Yes Moog sells rubber bushings. If you want to upgrade from there I suggest Polygrahpite bushings. It has the same durability as urethane bushings, but they are graphite impregnated so they won't squeak.

On the rubber bushings there is a inner and outer steel sleeve if I wanted to replace with new rubber how hard is it to remove the outer sleeve?
Could you all tell a big difference between the old rubber and poly?
