Active toe in the rear!, poly bushings already crapping out... Options

[cha914]

So I have the car up in the air dealing with the oil as usual, and I happen to lean on the inside of one of the rear tires and I hear a sucking sound as the control arm moves about a 1/8th inch...hmmm...check both the large nuts and they are both tight as they should be.

DAMN...it seems that the inside bushings on BOTH control arms have failed. They both move about 1/8th inch (IMG:http://www.914world.com/bbs2/html/emoticons/icon8.gif)

Now, I know these wern't the best solution, but I expected them to last more than 4000miles...I do have a pretty agressive alignment -2* camber and 0 toe in the rear, but I am still on street tires, and almost all the driving I have done has been on the street maybe 3 autox's...

I grooved the bushings for grease on the inside, and I reamed them out so that they would fit snugly but not have to be pressed on...and I also checked to be sure that I shaved the outer edge down so I wouldn't get the wallow effect I have seen posted here so many times...however, it seems that none of this mattered because its been maybe 4K street miles and I now have the neato active toe...

Sooooo...I know the real answer is to go to the muller bearings, but in the case that I can't get that kinda scratch together, did I do something wrong in the prep of these bushings, or do they just not last more than 4k miles?

It seems like the inside of the bushing has been wallowed out, so that the control arm is moving around the center rod, the rod doesn't seem to be moving, but I know that is a dangerous assumption. I also find it strange that both sides have failed in the same way, at the same time...I guess I was consistant in whatever I did wrong (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

Any thoughts, comments welcome...
