ovaling of the rear suspention ear, +installation tips on rear susp bushings Options

[ChrisReale]

I fear my right rear suspention ear has been ovaled due to rubbing of the trailing arm shaft and the ear. With the rear jacked up I can move the wheel back and forth. Not much, but I see the trailing arm moving at the ear. I want to catch this before it gets more serious. How much would it cost to fix the ear hole? Is this something I can do in my garage, or should I let the pro's do it? I "might" have access to a welder, but I dont have access to experience.... :toilet:

Chris, I don't know anything about derlin...what is special about it itself...and what is so unique about your installation?
Thanks for the help,

Delrin is a hard (usually black) plastic, much better suited for suspension bushing material than Teflon, Nylon, Poyurethane, etc. It is of a higher quality than the polygraphite bushing material and it will last longer. The polygraphite is molded, while the Delrin must be turned on a lathe.
I prepare the trailing arm by reaming the hole accurately, so my bushings press in with the right pressure and they are aligned to one another. That way the shaft, which I have ground slightly to provide a fresh smooth surface, fits without binding. I also add grease zerks to the trailing arm to lubricate the bushings, and trim the end of the bushings to fit the shaft precisely. I have seen some variation in length of the shaft, as well as the trailing arm, so there is no "one size fits all" solution.
