Well ive already changed the pair for the same manufacturer parts so hopefully just a visit to have it tracked should sort it out.
Ive measured them and from the centre point of the ball joint to the centre point of the bolt hole (crossmember mounting) the new ones appear to be 5mm ish shorter, but i think this is down to my old ones having proflex bushes being fitted on that end and they seem to be off centre which makes them a tad longer compared to the new ones. So with the new ones being that bit shorter it would pull the wheels in giving me the toe out ?
