Hi guys
thought i would post a link up to a ball joint repairer who is based in Liverpool.
Of particular interest to mx6 owners with 4ws and the cost of replacement arms. This guy did mine yesterday (fascinating to watch) and I have now got the tightest balls imaginable. His main business is doing ball joints on heavy plant and commercial vehicles so the repair has to be strong. if you take the car to him he can even do the repair without removing the arm from the car!

anyway try him out his website is
Ball Joint Restorers
I have no affiliation to him other than being a happy customer
cheers
john
