MOT ball joint advice from Delphi

Delphi is recommending garages replace entire ball joints when MOT inspections reveal damaged dust covers.

Although a car could pass the new MOT test if cracked dust covers are replaced with new boots, this doesn’t address the potential for damage to the ball joint.

Delphi says the joint could have been exposed to 51 weeks of dirt, debris and grease loss if a boot was damaged shortly after the previous MOT.

It says replacing the entire joint is the best approach to take as a result, and also suggests universal fitment boots designed to get cars through the new MOT might not be suitable in all applications.
