in the middle of a nightmare week with ma v6 cougar , needed 2 new drive shafts at the weekend due to failed abs rings and a couple of drop links into the bargain , and today been told by the garage that the gearbox is needing replaced as the diff is locked , surely not a coincidence that they replaced drive shafts and now I have a issue with diff lock . Really not looking forward to the garage getting back to me with price for latest fix , the 17yr old might need to be gone , at its current rate of spends is costing more than i'm earning .
