The RRT control arm is mainly the ball joint. I won't touch that.Originally Posted by BigKriss
I am mainly concerned about the play and the wear on the Thrust arm bushing.
We didn't take any pictures but I will try to get some ASAP.

The arm is design to flex ( I will have to make a drawing at some point) at the point of the bushing up and down but also a little bit side to side.
I will remove the flex side to side, it will move only up and down.
This won't affect the rest of the car, but the car will react quicker from steering inputs.

sorry Bruno. I thought the balljoints on the RRT arms where stock and the bushing's where a spherical bearing type. Here's a pic

Bruno's Inserts

Here's what Bruno's inserts looked like. The red poly inserts take the place of the green that come with the replacement bushings.

Well, considering that the supplier left with my money and I would need to create a mould, I went another route.

That would be great... and very expensive I am sure...
I still have to do some testing on the part and evaluating options.

I'm interested in full metal bushings
Keep me in the loop.
BTW, are your rear subframe mount rings supposed to fit loosely? It seems as though two would fit in the alloted space.

TWO... wow that is a lot of gap. No if the mount isn't broken, only one should fit tight.
If you can put two, that means that your subframe mount is completely broken and the subframe is allowed to move a lot.

I removed the entire rear subframe 3 years ago when I installed my Quaiffe 3.46 differential. I had all new bushings pressed in while the subframe was out. New dogbones too. I drive it on the track a lot, and it doesn't seem loose or sloppy. When I installed the rings, the car was on jack stands under the subframe. I don't know whether the gap decreased when the car was back on the ground, but it handled fine. I even got a few complements on how well balanced the suspesion setup was.
