I just had my mechanic change my wheel bearings on all 4 wheels. It still making humming noise. He told me he needed the shim for the hub. Problem:
He does not know what size and is not able to determine the thickness he needs. Jaguard dealer parts tells me they have 25 different shims between 2.2 and 3.7 mm !!! AND EACH ONE at $ 24.00 a piece non returnable!
WHAT DO I DO???????? Please help if able to.
Forgot to mention this is a 1991 XJ6 Sovereign
