Common issues with truck suspension systems include the following

First, damage or fatigue of the air springs. Springs are critical components of the suspension system, tasked with supporting the vehicle's weight and absorbing shocks. They may fracture or lose elasticity due to prolonged heavy loads, material fatigue, corrosion, or manufacturing defects.

Second, failure of shock absorbers: The primary function of shock absorbers is to regulate air spring rebound and minimize body vibrations. They can fail due to internal oil leaks, aging seals, or piston wear, resulting in increased jolting when traversing uneven surfaces.

Third, damage to control arms (either A-arms or trapezoidal arms): Control arms connect the wheels to the vehicle’s frame and help maintain proper wheel alignment. They may bend or break from impacts, wear over time, or rusting—leading to unstable handling.

Fourth, wear on ball joints: Ball joints facilitate rotational movement between the wheels and frame; worn ball joints can produce abnormal noises and hinder steering responsiveness during turns.

Fifth, aging of bushings and rubber cushions: These components serve as insulators against vibration and noise; deterioration can result in unusual sounds and compromised handling.
