Shackle Replacement

[robinsonwr]

Does anyone know the best product to use on the shackle bushings to increase free movement? I was thinking about using petroleum jelly/Vaseline to help free movement and hinder binding. Is this a good idea or not? Is there a particular torque spec for the installation of rear shackles?

Do you have rubber or Poly bushings? I don't think petroleum jelly and rubber are compatible. I'd use silicone grease or dielectric grease. Torgue spec is 40 ftlbs.

I don't think they really need lube on them if you use rubber.
Not that it would hurt. They just aren't supposed to rotate that I'm aware of.
If you use OEM rubber, I lower the car to make the shakles in the right positon and tighten them so the rubber isn't in a bind.
The same way one does the upper contol arm bushing on the front.
I just put my first set of poly shackle bushing in.
Used the lube that came with the lower control arm bushings for those.
( By the way, I've run LCA poly for years with no trouble)

When I worked at a spring shop we used food grade never seize. It's white and all rubber bushings get tightened with full weight on them... the never seize keeps everything from squeaking. Everything else will rot the rubber.
