FixGrinding Noise — What It Usually Is, and What It Costs
Grinding is metal meeting metal somewhere it shouldn't, and the records make the odds plain: most grinding visits end at the brakes, with wheel bearings the strongest runner-up. Where and when it grinds sorts the two out quickly.
This page is a focused cut of the broader Noise While Driving records.

Real repair reports
These are recent, paid visits for this complaint — the words as the owner said them, and what it turned out to be.
Car owners said
“grinding noise when applying brakes”

“Replace rear brake pads and rotors. Clean and lube all caliper slides. Road test verify fix.”
“Diagnose right rear wheel bearing is loose”
“- Noise heard from the rear - at first when turning the steering wheel to the right the noise was heard - lately when braking facing downhill the noise can be heard. Check and Advise.”
“Lh rear caliper froze inside pad grinding.”
Grinding when you brake
If the grind appears or sharpens when you press the pedal, it's brake pads worn to the metal — the dominant outcome. The brakes-grinding records carry that story, including why waiting turns a pad job into a pad-and-rotor job.
Grinding while rolling
A grind or growl that's there whether or not you're braking, and that changes on gentle swerves, is a wheel bearing — the second-largest family in these visits.
Grinding on turns
Grinding or clicking mainly in turns points at a CV joint running dry inside a torn boot. Caught as a noise, it's an axle replacement; ignored, it's a car that stops driving.
