How to Solve the Abnormal Noise When Volkswagen Lavida Passes Over Speed Bumps?
4 Answers
Volkswagen Lavida produces abnormal noise when passing over speed bumps due to the following reasons: the inner and outer tie rod rubber bushings may cause squeaking sounds on uneven roads; severely damaged bearings may occasionally produce a clicking sound when passing over speed bumps; shock absorber oil leakage; the Mazda 6 front suspension is a double-wishbone independent type with a stabilizer bar; broken engine or transmission mounts; and abnormal noises from door hinges or trunk hinges under stress. Causes of abnormal noise from the chassis: Abnormal noise from the chassis is caused by various factors such as aging of the stabilizer bar link ball joints, excessive clearance in the steering tie rod ball joints, and damage to the cushioning components on the chassis. The function of the stabilizer bar: It prevents the car from rolling when cornering.
I've been driving a Volkswagen Lavida for several years and have encountered similar abnormal noises. The creaking sound when going over speed bumps usually prompts me to start by checking the suspension. Worn-out stabilizer bar bushings are prone to making noise—they're rubber components that can crack or wear out over time. I often squat down to inspect the chassis, gently shaking parts with a screwdriver to check for looseness. Another possibility could be shock absorber issues; if they're leaking oil, they might produce squeaking sounds. During regular driving, I make it a habit to periodically check chassis bolts, especially on the control arms and links, tightening them if they feel loose. If I can't handle it myself, I recommend taking it to a repair shop for a thorough inspection with the car lifted. Don't delay too long, as a dislocated suspension could dangerously affect handling. Always ensure safety and have the right tools before attempting any fixes. A simple start would be replacing the bushings first.
As someone who frequently repairs Volkswagen models, the common points for abnormal noises when the Lavida goes over speed bumps are several. I pay attention to the stabilizer bar bushings—once they age, they squeak, and you can feel looseness when pushing by hand. Then there are the shock absorber bushings or ball joints, which produce louder noises when worn, especially noticeable at high speeds. Another low-level mistake is loose chassis bolts, which can happen with both new and old cars. For solutions, during my simple checks, I use a torque wrench to tighten key areas and recommend owners regularly replace the bushings—they're cheap and effective. If that doesn’t work, send the car to a repair shop for a lift inspection. When parking, avoid potholes to extend component lifespan. Safety first—don’t ignore such noises; addressing them early saves money and hassle.
My Lavida sometimes makes a creaking noise when going over speed bumps. The issue is mostly with suspension components, such as the stabilizer bar bushings or shock absorbers. The rubber parts wear out over time and lose effectiveness. I usually try to inspect the chassis myself for any foreign objects or looseness. If I can't pinpoint the cause, I just drive straight to the 4S dealership for a check-up—they're more professional. Driving habits are crucial; avoid hitting speed bumps too hard to minimize wear. Cost-wise, bushings are just a few dozen RMB to replace. Safety comes first—if the noise gets loud, get it fixed promptly to prevent small issues from becoming major problems. Remember to schedule regular maintenance and inspect the undercarriage.
