Rubber or Poly for a Daily Driven Corner Carving Street Machine?

JoesEdge said

I was actually looking at your bushings today. Can you explain them a bit more?

From what I understand, Delrin is a harder plastic that resists wear and is great for pivot points.

So why does it not require the outer shell and do you recommend using greasable pivot shafts or are those not needed? Can you explain how they are installed?

I'm guessing you pull the outer shells out of the LCA and then press these in and then insert the pivot shafts?



Can you explain this a bit more? I'm not understanding. Is it because they are difficult to remove? As far as resources, I do have a 20 ton press in case that helps.

I just installed a set of Pete's Delrin bushing's in a set of LCA that I'm rebuilding. The bushing is designed to fit in the entire opening of the previous rubber bushing, thus eliminating the outer shell. It should provide for a more linear movement I suppose, since it's all one piece rather than a bushing and a shell. The pin is pressed in with the bushing all at the same time as one piece.

Pete recommended using this grease http://www.jegs.com/i/Energy+Suspension/355/9-11104/10002/-1 and here's the pivot shaft http://www.americanmuscle.biz/34571_lower_control_arm_pivot_poly_p/34571.htm
designed for the new delrin bushing. That grease I guess has helped eliminate a lot of squeaking so a greasable pivot shaft isn't needed. I think Hotchkis ending up using it to eliminate some persistent noise problems.
