I agree with Dobz ask for an invoice stating that the bearings were changed.
(Side comment)Recently got my timing belt done for shits because I didn’t know if it had been done at 100,000Km and my mechanic recommended that the bearings be changed as well . (car doesn’t back fire now)
Do u live in a dusty area because I know with trucks that i drive get squeaky belts because a glaze has built up on the pulley from bull dust and alike (because i didn’t care i just put a bit of soapy water around the problem area and the sound would go away)
?
