What is the solution for low-speed abnormal noise in the Regal?

[Colin]

The solutions for low-speed abnormal noise in the Regal are: 1. Replace the shock absorber; 2. If the shock absorber pressure bearing is aged or abnormally worn, replace or lubricate it directly; 3. Replace the shock absorber spring and wheel bearing. Taking the Regal 2020 552T Elite as an example: It is a mid-size 4-door 5-seater sedan under SAIC-GM Buick, equipped with a 9-speed automatic manual transmission, with a top speed of 205 kilometers per hour. The Regal 2020 552T Elite uses a 1.5T inline four-cylinder engine, with a maximum torque of 250 Nm and a maximum power of 124 kW. The front suspension type uses MacPherson independent suspension, and the rear suspension type uses multi-link independent suspension.

When I was driving my Buick Regal before, I encountered a squeaking noise at low speeds, especially when turning. I first checked the tires myself to see if there were any stones stuck or abnormal wear, but everything seemed normal. Then I tried braking to see if the noise changed, and found that it didn't disappear with braking, ruling out brake issues. Next, I inspected the suspension components and felt some looseness when shaking the wheel by hand—it turned out the rear suspension bushings were worn out. I replaced the part for just 200 yuan and fixed the issue. Some friends also mentioned that loose underbody guard screws or bearing wear are common causes. They suggested parking the car on a flat surface and manually shaking the body to locate the noise source. Don't take it lightly—unresolved noises could affect driving safety over time. It's best to visit a 4S shop or professional repair station early for a comprehensive diagnostic check to prevent small issues from becoming major problems.

As a DIY enthusiast, I enjoy troubleshooting rattles myself. For low-speed rattles, start with the basics: check if the tire pressure is balanced, as uneven pressure can cause a humming noise. Then, listen to see if the sound is coming from the braking system—if there's a grinding noise when lightly braking, it might indicate worn discs or pads, requiring cleaning or replacement. Next, inspect the suspension for loose or cracked ball joints and bushings, and try tightening the bolts with a wrench. The steering gear on a Regal might sometimes squeak due to lack of lubrication; adding some grease can help. If the noise disappears with speed, it's often caused by the chassis skid plate rubbing—fix it by securing it with a rubber pad. For more complex issues, it's best to visit a shop and use a lift to check the suspension height. Don't skimp on these small tasks—they can save you hundreds in repair costs.

Low-speed abnormal noises are mostly caused by aging mechanical components. For example, worn bearings can produce a humming sound during low-speed turns; cracked suspension bushings may result in a clunking noise; while brake system issues often manifest as squeaking sounds when braking. After stopping, manually check the wheels for looseness—if there's any play, it indicates parts need replacement. I believe safety comes first, so don't delay—take the car to an authorized repair shop for diagnosis. Technicians can identify the problem through vibration tests, and repairs typically involve quick replacements like bushings or wheel hub bearings, costing only a few hundred yuan. However, major issues such as a faulty steering gear could cost over a thousand yuan to fix.

Regular maintenance can prevent low-speed abnormal noises. I recommend checking the tightness of chassis screws quarterly and applying some anti-rust oil to avoid rust friction; clean the brake system every 6 months to prevent pin sticking noises. Inspect suspension component rubber bushings every 20,000 km for wear, replacing small parts early saves major repairs. Document noise characteristics like timing and location to help technicians quickly diagnose. Prevention is better than repair - develop good habits to prolong vehicle condition, small investments bring great peace of mind.

When hearing abnormal noises at low speed, first slow down and park safely by the roadside. After getting out, gently shake the car body to locate the sound: if a squeaking noise comes from the tires, check the air pressure or tread; a clunking sound indicates suspension issues; a rustling noise may suggest a bad bearing. Do not continue driving forcefully to avoid damaging parts—towing to a repair shop for inspection is more reliable. Remember, providing accurate details aids diagnosis. Conduct a pre-trip inspection to prevent unexpected incidents.
