Wolf,

Just relubed the trailing arm poly-bushings hoping to stop a squeak. These are pretty much the same as the front suspension bushings.

I have found that after lubing poly bushing halves, and pushing them into the housing, the air trapped between the halves quickly pushes the bearings apart. Hard to slip the bushing assembly into the chassis when it is fighting you by expanding back apart.

This time I cut a shallow v-shaped groove in the poly-bearing surface from the inside edge to but not through the outer flange.

Now, when you compress the bearings halves with a vise, the air is expelled as they push together. A plus, the groove holds grease and the center cavity can be packed with grease. Aside they are a LOT easier to install when they don't rexpand before you get the assembly into the chassis.

With out a groove in the poly-bearing surface the fit is so tight I doubt a typical grease gun could force the silicone grease out around the bushing anyway...add the groove, and a zerk fitting couldn't hurt.
