Why does the Chevrolet Sail chassis make abnormal noises?
3 Answers
Abnormal noises can be caused by interference between components, loose bolts or nuts, universal joint failure of the drive shaft, damage to ball joints, suspension, or connecting brackets. Interference between components: Due to impacts or installation of additional equipment, mutual interference occurs between two components. This can only be resolved by reshaping, repairing, or replacing the relevant components to eliminate interference. Loose bolts or nuts: Long-term driving on poor road conditions can naturally loosen bolts; improper disassembly or installation may damage bolts; insufficient tightening torque or incorrect bolt specifications. Bolts and nuts need to be tightened or replaced.
Recently, I've been hearing constant creaking noises from the chassis when driving my new Sail. This is commonly caused by suspension system issues, such as aging shock absorbers leaking oil, or loose springs not properly secured. It could also be due to worn steering components, with ball joints in the tie rods creating friction noises, especially noticeable during turns. If chassis bolts are loose, you'll hear clunking sounds on bumpy roads. Sometimes, unbalanced tires or deformed wheel hubs can indirectly cause vibrations transmitted to the chassis. Leaving it unrepaired may worsen parts and compromise handling safety. I recommend visiting a repair shop immediately for a thorough inspection using a lift, preferably including chassis lubrication and tightening. Try to avoid potholes while driving to reduce impact.
I've encountered similar abnormal noises before, and a simple diagnosis might point to loose chassis suspension components. Start by checking yourself: crawl under the car to see if screws and nuts are loose, especially around the rear axle or steering connections; shake the tires to check if the bearings wobble. Steering mechanism wear is common after long-term vehicle use, and lack of timely lubrication can cause squeaking. Rusted chassis protective plates are also a potential cause, especially during rainy seasons when rust can lead to metal friction sounds. Untreated abnormal noises can accelerate part damage and even pose a risk of steering failure. Don't delay—find a reliable repair shop to diagnose the issue; replacing a small part might solve it.
