I have a 2002 Yukon 4WD. I detect a low roaring/grinding noise from left front wheel area when I turn left or right into a drive way or parking slot.
I thought it to be the whell bearings so I had them replace not that: Then I had the brake served and replaced the rotors and pads. Not That either.
There are a lot of things to replace under the front end
RepairPal Certified shops can diagnose and repair your 2002 GMC Yukon XL 1500. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
my best guest would be wheel bearings. Did you take back to the shop after they were replaced to have them test drive it ? Has the sound change since the work was done?
