New bushes ordered. Can't see that panhard coming complete with bushes Orangebean so i've gone for the same polys that i fitted on the front.
Since this thread was originally about my tracking i'll update the state of play. When it went to the garage, the steering wheel was centre and the steering box was centre. After the radius arm bushes had been done (again), steering wheel had moved off centre to between 10 and 11 o'clock. Only thing that was removed was the passenger balljoint for the trackrod which was then swung out of the way to get the arms off. Track rod wasn't adjusted and it went back on no bother. Garage man suggested that the bushes that he took out were that bad that although the box was centered and the steering wheel was centered, the steering still wasn't actually centered as it was bent out of shape or strained in some way. Now with new bushes, it's relieved any tension or whatever and relaxed the wheel to where it actually wants to be. It does drive straight now and the resistance from left to right feels the same. Just need to get a spanner on the draglink and straighten the wheel which i forgot to do today whilst i was doing the panhard rod bushes. And since doing the panhard rod bushes, it's improved once again to the point where i reckon it might be fixed. Only trouble now is that you can really feel the difference between the front and back end which on investigation shows up that the rear bushes are also fubar.
