Abnormal Noise When Car Shakes?

[LaEmiliano]

Abnormal noise when a car shakes is caused by friction between the car door and the frame due to shaking, or friction between steel plates due to poor welding. Below are descriptions of different abnormal noises: 1. Piercing belt squealing: Caused by belt slippage. 2. Sharp metal-on-metal friction sound: Due to damaged bearings in the generator, water pump, or power steering pump. 3. Engine air leakage sound: Result of a blocked exhaust system, or a leaking or broken vacuum tube. 4. Low "thumping" sound: Caused by deformed, bulging, severely worn tire treads, or insufficient tire pressure.

A creaking sound when the car shakes is mostly due to loose chassis components. Last week when I drove over a speed bump, I heard a metal grinding noise near the left front wheel. After inspection, it turned out the lower control arm ball joint was worn. The mechanic said such aging parts are particularly noticeable on bumpy roads, and you might also hear a clunking sound when turning, which indicates an issue with the tie rod. The worst scenario is a problem with the CV joint, which causes a clicking noise and severe shaking when accelerating during turns. It's recommended to check all rubber bushings and connecting parts while the car is lifted during routine maintenance, as small issues can become more expensive to fix if left unattended.

Attention to those who have modified their chassis! My friend's car, which had its body lowered and fitted with stiff suspension, made a clanking noise when driving on rough roads. It took three inspections to find out that the thickness of the aftermarket sway bar bushings didn't match, causing metal to hit metal directly over bumps. Those who modified their exhaust pipes also often experience a buzzing resonance sound during hard acceleration, which happens when the clamps aren't tightened properly and the pipes rub against the chassis. These issues become particularly noticeable after track days, so it's crucial to check the torque of subframe bolts and the clearance of aftermarket parts.

Attention, female car owners! Last time when I was waiting at a red light with the AC on, my car shook like a massage chair, accompanied by cracking sounds from plastic parts. During maintenance, the mechanic said it was due to loose bolts on the AC compressor bracket, causing an imbalance when the fan rotated and leading to engine compartment vibrations. It could also be caused by carbon buildup in the intake manifold resulting in cylinder misfires, with black smoke puffing from the exhaust pipe. Key checks include whether the engine mounts have collapsed and if the spark plugs need replacement. Remember to clean the throttle body every 20,000 kilometers – a dirty fuel system is particularly prone to shaking.
