What Causes the Chassis Noise in Emgrand?
3 Answers
Automobile chassis noise can be attributed to the following reasons: 1. Suspension System: The noise heard when the vehicle starts is usually due to a fault in the suspension system, which may be caused by loose or damaged engine mounts. 2. Steering System and Suspension System: The noise heard when the vehicle is turning may be due to faults in the steering system and suspension system, as the vehicle tilts during the turning process, causing the suspension system to deform and participate in the movement. 3. Brake System Components: The noise heard when the vehicle is driving on good road conditions may be due to faults in the brake system components, or it may be caused by loose or worn brake system components, out-of-round brake drums, or uneven brake disc surfaces. 4. Bearings: It could also be an issue with the bearings that connect the moving and stationary parts of the vehicle. If it is a bearing problem, the driver can identify it by applying slight brakes. If the noise remains unchanged when the vehicle is moving at a constant speed with the brakes applied, then it is a bearing issue.
I've encountered the issue of abnormal noises from the Emgrand's chassis several times. It usually makes squeaking sounds when going over speed bumps or rough roads, often indicating a problem with the suspension system. Common causes include aging rear shock absorbers or oil leakage from the dampers, which require replacement. Additionally, damaged control arm bushings can cause continuous rattling noises from the chassis, which can be quite annoying. Other possibilities include loose steering tie rod bolts or foreign objects stuck in the brake discs, which can also generate noise. I remember when I was driving my Emgrand, I initially thought it was a minor issue, but after inspection, it turned out that the tire bolts weren't tightened properly, which could have been a safety hazard. I recommend asking a knowledgeable friend or a professional mechanic to listen to the noise and using a jack to lift the car to check for rust or damaged parts on the chassis. Also, in cold winter weather, the rubber components of the chassis tend to harden, leading to more noises. Regular maintenance and lubrication can extend the lifespan of the chassis. Address the issue early to avoid affecting your daily commute.
As an experienced driver who has driven various models, I believe the abnormal noises from the Emgrand chassis are mostly caused by wear and tear of suspension components. Aging rubber bushings are the most typical, producing constant clicking sounds during turns or starts; when shock absorbers fatigue and internal oil leaks, increased vibration leads to rattling noises. Loose tire bolts are also common—I often checked them myself when I was younger. Worn tie rods or drive shaft rubber joints result in more noticeable noises at high speeds. Start with simple checks: listen for the noise source while driving slowly on flat roads, then manually shake the wheels to test. If the noise occurs after braking, check for any obstruction in the brake discs. Chassis noises can range from minor to severe, and neglecting them may damage the drivetrain. It's best to visit a repair shop for a thorough diagnosis using a lift—safety comes first. Don't take risks on the road.
