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:

I'm going to shoot two short video's tomorrow of the roller bearings installed on a FP car. I will "work" them by hand to show the lack of drag. Something insteresting that is being missed in this thread: Your plastic bushings can be reamed/trimmed/polished.. whatever and they can spin freely while testing them on the bench. The problem is: all this changes when the weight of the car is on the bushings. Today, Tony and I where taking a look at Bontempi's FP car trying to find a measuring point for the trailing arms....Tony pushed down on the left rear of the car (I had this apart less than 3months ago and it moved freely) the car took about 30+ seconds to rebound from his "jounce". NOW, our roller bearing cars move up and down with a "jounce". I promise a well installed and greased plastic bushing has more drag than any of the roller bearing cars. I know the roller bearings are not really designed for "Joe Blows" street car.
