What does that noise from my car mean?
Short answer:Noises are one of the best diagnostic clues. The techs at Labor Only Auto Repair use squealing, grinding, clunking, clicking, whining, and ticking to point to different systems.
Squealing on light braking is usually pad wear indicators doing their job — it's an early warning, not an emergency, but don't ignore it. Grinding on braking means the pad is gone and you're eating into the rotor. Clicking during a tight turn from a front-wheel-drive or AWD vehicle usually means a failing CV axle.
Whining that changes with engine RPM often points to a power steering pump, alternator bearing, or accessory belt tensioner. Whining that changes with vehicle speed but not RPM usually points to differential, transfer case, or wheel bearing. A rhythmic thump that speeds up with the vehicle is often a tire issue or wheel bearing.
Clunking over bumps is suspension — worn sway bar links, ball joints, control arm bushings, or strut mounts. Ticking from the engine can be as simple as an exhaust manifold leak or as serious as a lifter issue. Bring us a good description (when it happens, hot or cold, at what speed, with what load) and we'll pin it down fast.
