What Causes the Chassis Noise When Driving a Corolla on Rough Roads?
1 Answers
Corolla chassis noise reasons when driving on rough roads are as follows: Loose Bolts: The noise caused by loose bolts is easy to understand. Parts that should be firmly fixed but are not will naturally rattle and produce noise. The noise from loose screws in the chassis is not always a squeaking sound; it can also be a subtle metal knocking sound, especially noticeable when driving on bumpy, rough roads. Examples include loose bolts on various suspension arms, links, and shock absorbers. The mounting bolts of the engine guard plate can become loose after prolonged driving on rough roads, causing noise between the engine guard plate and the chassis. Braking System: Noise from the braking system is usually sharp and continuous. Worn brake pads, uneven wear between the brake discs and pads, among other reasons, can cause brake noise. Brake pad issues are one of the main causes of noise, as brake pads wear out over time and are consumable parts that require regular replacement. Brake pads should be considered for replacement when their thickness wears down to less than 3mm, and must be replaced at 2mm as the absolute limit. Generally, front brake pads last about 50,000 kilometers, while rear brake discs and pads last about 120,000 kilometers. Additionally, poor-quality brake pads (too hard) can also cause noise. Besides brake pads and discs, malfunctions in the brake caliper, master cylinder, or wheel cylinder can also produce noise.
