What Causes Abnormal Noises in a Car?

[DelKingston]

If the car makes a squeaking sound when driving at low speeds, it is likely coming from the suspension. The car's suspension includes components such as links, springs, shock absorbers, and stabilizer bars. If any of these parts are abnormal, such as loose bolts, they may produce abnormal noises due to movement. The details are as follows: 1. Inside the car: If the noise comes from inside the car, it is necessary to check whether the clock spring under the steering wheel and the universal joint inside the steering column are functioning normally. Wear or malfunction of these two components can cause abnormal noise. 2. Outside the car: If the noise comes from outside the car, it is necessary to check whether the upper plane bearings of the two front shock absorbers are worn, whether the ball joints of the steering gear are loose, and whether the internal rack and pinion of the steering gear are worn. Malfunction of these three components can lead to abnormal noise in the vehicle.
