All,
Over the last thirty years I can recall these fixes for squeaking polyurethane bushings:
1) Zerk fittings--- periodically apply grease, the most common fix and seems to work well
2) Application of anti-seize at the time of installation---I have heard of this once or twice, but I do not know of anyone who has actually done it nor how effective it is.
3) Graphite impregnated polyurethane bushings---available for years. I don't know how effective they are, but given the lack of negative reviews, they seem to be a good option
4) Special polyurethane bushing lube---several years ago a fellow Pantera owner installed the poly bushings and was also sold a packet or two (condiment-sized) of allegedly special purpose polyurethane bushing lube. It seems to work as I have heard no comments from the owner nor squeaks from the Pantera.
I am curious if anyone has any experience with the two uncommon options of using anti-seize or the secret polyurethane lube?
Warmest regards, Chuck Engles
