Wheel Alignment
The front wishbones were  rusting quite badly so I decided to remove them and repaint. Before dismantling,  the positions of the ball joints etc. were carefully marked so as not to disturb  the wheel alignment. After de-rusting with a rotary wire brush, rust remover was  applied and the clean metal was primed with Galvafroid galvanised paint and then  top coated with Smoothrite. It seemed sensible to also replace all the bushes  and ball joints at the same time. So as to maintain the same wheel alignment I  had carefully marked the position of the old ball joints and fitted new. The car  semed to drive OK and so I thought no more about it until a recent pre MOT check  revealed the abnormal wear to both tyres, the offside shown below:

Checking the Toe, the  wheels were found to be Toeing out, not in, by a significant amount. The Camber  had also increased from Negative 1 to 2 degrees. As the new ball joints were in the same position as  previously there must be a subtle diffference in their construction that altered  the Toe-in and Camber. The result illustrated here and after about 800  miles, so the wear is fairly rapid. The tyres were already half worn (about 4mm  ) so not the end of
the world but it does emphasise the
necessity of checking both Camber and Toe after any alterations or  replacements to the suspension.  The cost of realigning your suspension will be significantly less than two new  tyres!
