What Causes the Squeaking Noise When the Front Wheels Go Over Bumps?
2 Answers
Front wheels squeaking when going over bumps is usually caused by damaged rubber bushings in the shock absorber system, and replacing them can resolve the issue. Below are specific details about the shock absorber system: 1. Introduction: In the suspension system, vibrations are generated when elastic components are impacted. To improve ride comfort, shock absorbers are installed in parallel with the elastic components in the suspension. Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers designed to dampen vibrations. 2. Principle: The working principle involves the piston inside the shock absorber moving up and down when relative motion occurs between the frame (or body) and the axle due to vibrations. The oil in the shock absorber chamber repeatedly flows from one chamber to another through various orifices.
The front wheels make a squeaking noise when going over bumps, and I suspect it's an issue with the suspension system. The sound resembles metal-on-metal friction, possibly due to severe wear of the lower control arm ball joint or suspension bushings, or poor lubrication caused by aging shock absorber rubber mounts. This needs immediate attention, as it could accelerate damage to other components and compromise driving safety. I remember mechanics back in the day often saying such noises are common in older vehicles, especially those frequently driven on rough roads. It's advisable to visit a reliable repair shop for a thorough inspection of the suspension system and to check for looseness in the ball joints and tie rod ends. Regular maintenance of suspension components can help reduce such issues.
