Chassis System Usage Issues

‌1.Aging and Cracking of Lower Control Arm Bushings‌: As the most frequently moving rubber cushioning components in the chassis, they are constantly pulled and strained by road bumps. Cracking and detachment often occur within 2-3 years, directly leading to loose chassis, abnormal noises when passing speed bumps, and steering wheel wobble at high speeds.

2‌.Oil Leakage and Failure of Shock Absorbers‌: Long-term driving on rough roads and frequent full loads accelerate the loss of internal hydraulic oil. After oil leakage, the damping effect is lost, causing the vehicle to continuously bounce up and down on bumpy roads, drastically reducing handling stability.

‌3.Damage to Half-Shaft Dust Boot‌: This rubber component rotates continuously at multiple angles with the half-shaft. When it ages and cracks, the internal grease is thrown out, causing the universal joint to quickly wear dry without lubrication, eventually leading to steering abnormal noises and power transmission stuttering.

4‌.Loosening of Steering Tie Rod Ball Joint‌: After the dust boot is damaged, sediment invades and causes dry wear, increasing the clearance of the ball joint. At high speeds, this results in steering wheel vibration and unstable vehicle body, with a serious risk of steering loss of control in severe cases.
