What Causes the Squeaking Noise from the Rear Wheels at Low Speed?

[Shirley]

Reasons for squeaking noises from the rear wheels at low speed are as follows: Suspension Issues: If the car makes a squeaking noise at low speed, it is likely coming from the suspension. The car's suspension includes links, springs, shock absorbers, and stabilizer bars. If any of these components malfunction, such as loose bolts, it can cause noise due to shaking. Braking System Malfunction: If the noise increases when lightly pressing the brake, it is certain that the braking system has an issue. Problems like excessively thin brake pads, uneven wear between the brake disc and pads, or faults in the brake caliper, master cylinder, or wheel cylinder can cause noise in the braking system, typically manifesting as sharp and continuous sounds. Loose Engine Belt: If the engine belt is loose, it can also cause noise. You can try pinching the belt with your fingers and twisting it. Note that this operation should be performed when the engine is cool. The twist angle should generally be less than 90 degrees; otherwise, the belt tension needs to be adjusted.
