A new noise from your car is always worth investigating — it is the vehicle telling you something has changed. At Tedious Auto Repair, noise diagnosis is systematic: we identify when the noise occurs, under what conditions, from which location, and what it sounds like — then test the most likely systems.
Noise Diagnosis by Type and Location
Knocking From Engine
[('On Cold Start — Gets Quieter When Warm', 'Piston slap (common on high-mileage engines), AFM/MDS lifter collapse, or timing chain slack. Monitor closely.'), ('Under Acceleration at All Temperatures', 'Rod knock — damaged connecting rod bearing. Stop driving immediately. Continued driving destroys the crankshaft. Oil change will not fix this.'), ('Detonation/Pinging Under Load', 'Engine pinging under acceleration indicates incorrect fuel octane, lean condition, or carbon buildup causing hot spots. Use premium fuel first and diagnose further if it continues.')]
Squealing
[('When Braking', 'Brake pad wear indicator — replace pads before rotors are damaged. Also: glazed pads or missing anti-squeal shim.'), ('When Turning (Not Braking)', 'Power steering pump or belt. Or CV axle — a click or pop when turning, worse in tight turns.'), ('At All Times From Engine', 'Serpentine belt or one of the driven components (alternator, power steering pump, AC compressor) with a failing bearing.')]
Grinding
[('When Braking', 'Metal-on-metal — brake pads gone, backing plate on rotor. Immediate repair required.'), ('When Turning or Changing Speed', 'Wheel bearing — a growling or grinding that changes with vehicle speed and sometimes changes when you turn the wheel.')]
Clicking or Popping
[('When Turning — Especially Tight Turns', 'CV axle outer joint failure. Common on high-mileage front-wheel-drive and AWD vehicles.'), ('When Braking', 'Loose brake caliper hardware or loose caliper bolt.')]
Humming or Droning
[('Changes With Vehicle Speed — Not Engine Speed', 'Wheel bearing failure. Hum gets louder as speed increases, may change when turning.'), ('Constant Regardless of Speed', 'Tire noise — cupped or uneven wear pattern.')]

Frequently Asked Questions
Why is my car making a knocking noise?
Engine knock on cold start that quiets when warm is usually AFM/MDS lifter collapse or piston slap. Knock under acceleration at all temperatures is rod knock — stop driving immediately, call (530) 826-4275. Pinging under acceleration is detonation from incorrect octane or lean condition.
Why is my car making a clicking noise when turning?
Clicking or popping when turning — especially tight low-speed turns — is almost always a failed CV axle outer joint. The clicking gets worse in tight turns. CV axle replacement from $299.99 at Tedious Auto Repair.
Why is my car humming?
A hum that changes with vehicle speed (not engine RPM) and sometimes changes when you turn the wheel is a failing wheel bearing. A constant hum that changes with tire speed is usually tire cupping or uneven wear. Free inspection at Tedious Auto Repair.
