Delrin Control Arm bushing - what should be rotating?

[chr2002ca]

Fellow forum members,

Just received some new Hotchkis lower control arms(1109) for my '69 Camaro. Installed them to the frame this afternoon with factory torque specs of 85ft/lbs. As I move either of the arms up or down, the entire Delrin bushing turns with the arm. Occasionally you'll see the arm barely turn on the bushing, but mostly the entire bushing turns. This means the outside surface of the bearing(made of Delrin plastic) is turning against the frame. That just didn't seem right to me so I called Hotchkis and they said it was normal. He said that I should put grease on the outside of the bearing between the bearing and the frame. I told him the instructions make no mention of that and that the bearing itself will not be able to keep that face lubricated because there are no channels to do that. Besides, shouldn't the bearing be rotating inside the smooth surface of the arm and not against the frame? He also said the bearing should rotate easily by hand inside the arm, but my mine sure as hell don't. I pulled one arm back off and I can barely get the bearing to turn inside the arm while it's clamped in my vice. He also said the bearing would 'eventually wear in", but the only thing that seems like it's going to wear to me is that Delrin plastic surface that's constantly rotating against the frame, and that will get so worn(and then loose) that the bearing will always just turn there instead of the arm turning on the bearing as it seems like it should. I can already see some marks in the Delrin where it was rotating against the frame.

Is this normal? Anybody think the bearing/arm clearance might be off such that it's not allowing the bearing to turn inside the arm as easily as it should? Grease too sticky? What would you do?

Thought I'd check with the guru's here before I proceed any further.
