What Causes the Abnormal Noise When Buick GL8 Goes Over Bumpy Roads?
2 Answers
Buick GL8 produces abnormal noise when going over bumpy roads due to loose engine mounts or door locks and door limiters with their internal components. Below is an introduction to the Buick GL8: 1. Power: The entire series is equipped with a 2.0T SIDI direct-injection turbocharged engine, with a maximum horsepower of 191 hp, a top speed of 205 km/h, and the entire series meets the National VI emission standards. 2. Advantages: The new Buick GL8 has been officially released, featuring innovative upgrades in design, power, handling, technology, and other aspects. In 2014, the Buick GL8 series achieved cumulative sales of over 600,000 units, setting a new milestone in its 15-year history of leading the domestic high-end MPV market in China.
I've encountered situations where the Buick GL8 makes strange noises on bumpy roads, which usually indicates minor issues with the suspension system. As a business-oriented MPV, the GL8's chassis is tuned for comfort, but frequent driving on rough roads can accelerate wear on suspension components, such as worn shock absorber seals or loose ball joints in the control arms. Increased vibrations on bumps cause friction in the gaps, resulting in creaking or thumping sounds. If left unrepaired, failed shock absorbers can lead to unstable body sway, affecting handling and ride comfort. I recommend finding a flat area and slowly going over a low bump to locate the noise source: front-end noises often indicate suspension issues, side noises may come from loose door panel clips, while rear noises could point to worn rear axle bushings. Don't delay - small problems can turn into major repairs. Regular maintenance checks on suspension and chassis fasteners can prevent such noises.
