What causes the rattling noise on the right side of GAC Trumpchi GS4?
3 Answers
There are many potential causes for vehicle rattling noises, each requiring specific analysis. Relationship between noise and engine RPM: Noise occurs only at idle or low speeds. Possible causes include: excessive clearance between piston and cylinder wall; overly tight piston pin or connecting rod bearing assembly; excessive clearance between tappet and guide hole; worn camshaft lobe profile. Relationship between noise and load: Many engine noises are clearly related to load. During diagnosis, you can test by progressively removing cylinder loads, typically using single-cylinder or dual-cylinder misfire methods to isolate one or two cylinders, thereby identifying the relationship between noise and load.
I have been driving the Trumpchi GS4 for over three years now, and recently encountered the issue of occasional "creaking" or "clicking" sounds from the right side, especially noticeable when turning or going over speed bumps. This could be due to loose parts in the suspension system, such as aging shock absorber sleeves or stabilizer bar links, or friction noise caused by worn brake pads. Initially, I thought it was a minor issue and didn’t pay much attention, but after a few days, the noise became louder, so I quickly took it to the 4S shop for inspection. It turned out to be slight wear on the right wheel hub bearing, and the problem was resolved after replacement. I recommend not delaying and taking your car to a professional shop immediately, as this can affect handling safety. Additionally, during regular maintenance, pay extra attention to loose chassis screws to avoid abnormal noises, saving both money and hassle.
After working in the car dealership for a long time, I've encountered quite a few cases of abnormal noises from the right side of the Trumpchi GS4. The most common issue is a faulty wheel bearing, which causes a continuous 'humming' sound while driving. Once it's worn out, it needs to be replaced. Other causes include loose suspension links, damaged CV joints on the driveshaft, or improperly secured brake calipers. When hearing such noises, I usually advise the owner to first try to locate the source by feel, such as whether the noise gets worse during acceleration. If they're not able to check it themselves, it's best to take the car to a repair shop early for a diagnostic with professional equipment—don't skimp on the small cost. By the way, if abnormal noises are left unattended for too long, they might damage other components, leading to more expensive repairs. Regular chassis inspections can help prevent these issues.
