Getting some from Smithy's as i suspect my steering bushes are shot. How do i remove the tension rod and whack on the bushes?

Removing the tension rod is a fairly easy removal of nuts and bolts that you will be able to see for yourself once you have your head in there, I would get somewhere with a press to remove and refit the new bushes though, people that tell you to hammer them in and out probably have never tried to do it as its not that easy.

Press them in using a jack and the jacking point on the car ;)

To remove the old ones you can burn out the rubber, then hacksaw through the outside (from the inside of the bush) and collapse it in on itself, leaving the rod intact and ready to press in the new one.
