1 Answers
Suspension fault means that there is a malfunction in the vehicle's suspension system. Common causes of faults are as follows: 1. Wear of ball joints or loosening of ball joint screws: Fault description: When the vehicle encounters bumps, a "clunking" sound is heard from the chassis. Fault inspection: Lift the vehicle and gently shake the tires to check the gap size, or use a pry bar to check the gap and looseness of each ball joint. Solution: Tighten the bolts and replace the new connecting rod, connecting ball joint, etc. 2. Aging or damage of the control arm rubber buffer: Fault description: When the vehicle encounters bumps, a "clunking" sound is heard from the chassis. Fault inspection: Use a pry bar to check each buffer rubber for cracks or aging. Solution: Replace the new swing arm buffer rubber or the new swing arm assembly. 3. Oil leakage or damage of the shock absorber: Fault description: A "clunking" or "squeaking" sound is heard when encountering bumps. Fault inspection: Check the shock absorber for signs of oil leakage, press the four corners of the car by hand to check the body's bounce and any abnormal sounds. Solution: Replace the new shock absorber. 4. Abnormal noise from the top rubber or plane bearing: Fault description: There is a "thumping" noise when passing over speed bumps, and a "squeaking" sound when turning the steering wheel in place. Fault inspection: Listen for sounds when turning the steering wheel in place or when lifting the car and turning the steering wheel. Solution: Replace the new top rubber or plane bearing, or add lubricant. Some sounds are caused by loose screws on the shock absorber. 5. Abnormal noise from the stabilizer bar bushing: Fault description: There is a "clunking" or "creaking" noise when driving and braking. Fault inspection: Check both sides of the bushing for clean, worn areas, and some are not easily detectable, usually eliminated by replacement. Solution: Replace the new stabilizer bar bushing. 6. Loosening of connecting and fastening parts: Fault description: A "clunking" noise occurs when encountering bumps. Fault inspection: Use a pry bar to check for looseness in each part. Solution: Tighten the loose screws.
