I noticed some squeaking noise on the front axle right side. I managed to locate the problem, which was the rear lower wishbone bush are also called the control arm.
Unfortunately it is not an easy job to change the bush out. The torsion bar needs to be slackened off and also the shock and stabiliser bolt removed before I have access to slacken the control arm. The easiest way to remove the lower ball joint is with a two–jaw puller.

Eventually I managed to get the bush out after removing the inner sleeve and the use of a Hack saw to cut the outer sleeve of the bush.
