What are the solutions for excessive noise in the Baojun 730?

[Cora]

Baojun 730 excessive noise solutions are: 1. Install engine hood sound insulation cotton; 2. Perform floor mat soundproofing, door panel soundproofing, trunk soundproofing, and wheel arch soundproofing; 3. Replace with quiet tires. Taking the 2021 Baojun 730 as an example, it belongs to the MPV category with body dimensions of: length 4780mm, width 1780mm, height 1740mm, wheelbase 2750mm, fuel tank capacity 52L, and curb weight 1420kg. The 2021 Baojun 730 features MacPherson strut front suspension and torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine delivering maximum power of 105PS (77kW) and maximum torque of 135Nm, paired with a 6-speed manual transmission.

I've been driving the Baojun 730 for a while, and the loud noise is really annoying. Common solutions include checking tire issues. When tire noise is loud, first inspect tire wear and pressure. If the tread is worn out, replace them with quiet tires like Michelin or Goodyear, which make a noticeable difference. For engine noise, install hood insulation foam; you can buy DIY kits online and apply them yourself—simple and cost-effective. To address wind noise, check the door and window seals; replace them if they're aged to reduce wind leakage. Suspension rattling might indicate damaged shock absorbers or bearings; lift the wheels and shake them to check for looseness, then visit a repair shop promptly for replacement. Regular maintenance is crucial—changing the oil and filters reduces vibrations, and a full soundproofing treatment, including the floor and door panels, can significantly improve noise levels. Don’t overlook safe driving—excessive noise can be distracting, so keep the car in good condition.

As someone frequently involved in car repairs, the Baojun 730 often exhibits excessive noise due to worn wheel hub bearings, producing a humming sound. During inspection, lift the wheel to check for looseness. Aging suspension bushings can cause abnormal noises, requiring replacement with new parts. Broken engine mounts lead to vibration and noise, necessitating tightening or replacement. For excessive tire noise, consider switching to quiet tires and adjusting the tire pressure to the standard level. Wind noise can be addressed by checking the side mirrors and window seals, adding sealing strips where air leaks are detected. It's advisable to visit a professional workshop for a comprehensive diagnosis, using instruments to identify noise sources, such as issues with the drive shaft or exhaust system. Regularly lubricate moving parts to prevent abnormal noises, and pay attention to the chassis and engine condition during maintenance to extend their lifespan.

I use my Baojun 730 for family trips, but the loud noise affects comfort. My solution is to add thicker floor mats to reduce road noise and place soundproofing material in the trunk to absorb sound. For tire noise, I switch to comfort-oriented tires and maintain moderate tire pressure. Regular engine oil changes help minimize friction noise. Replacing aged window seals improves sealing and reduces wind noise. Suspension rattles might be minor issues, so I promptly tighten loose screws. Safety comes first—excessive noise can cause fatigue, so I regularly check the car's condition to maintain a quiet environment.

I'm passionate about car modifications, and the excessive noise in the Baojun 730 can be resolved through upgrades. Perform full-vehicle sound insulation by adding noise-reducing materials to the engine compartment and door panels. Switch to quiet tires like Pirelli to reduce tire noise. Address wind noise by installing door sealing strips and windshield deflectors. Replace the suspension system with high-performance shock absorbers to minimize abnormal sounds. For engine noise, inspect the exhaust system and add a muffler. DIY projects are fun—purchase a kit online and install the sound insulation layer yourself. Regularly wash the car to maintain a smooth body surface, reducing wind resistance noise, and enjoy a quieter driving experience.
