Squeeking Trailing Arms

[Clois Harlan]

Last year I switched out my stock trailing arms with the beefier boxed aftermarket trailing arms. I also replaced my old rubber bushings with the stiffer Polyurethane bushings.

Problem is, now everything squeeks like an old Chevy and I was wondering what everyone is using to lubricate these bushings?Also, did any of you drill and tap holes and insert greese zerts in your trailing arms? If so what kind of greese are you using?

Thanks,

Clois - I too had the most awful heavy "creak" from my suspension (although at the front, not the rear). Turned out to be dry "nylatron" wisbone bearings, a clean up and a touch of LM (general purpose) grease sorted it out fine. Also a tip is to not tighten up the bolts that form the swivel point - I rely on the nylock nuts to keep them in place (although checked regularly - I like living too much).

Yep, urethane sqeaks. I have sucessfully used silicone grease to quiet them. But reapplications are frequent to stop the sqeaks. I later replaced the bright red urethane with "polygraphite" urethane which has graphite impregnated in it to lube it, seems to work well on my chevy. The area that sqeaks the most on my trailim arms was not the circumference, but the flat faces that have washers squeezing against them. If you are lazy you can just saturate the bushings with prolong spray lube without disassembling anything, but you'll have to do this often.
