How to Solve the Abnormal Noise When the Baojun 730 Passes Over Bumps?
2 Answers
The solution to abnormal noise when the Baojun 730 passes over bumps is: 1. Check if the shock absorber is leaking oil; 2. Determine which suspension is producing the noise; 3. Press down on the upper part of the suspension for each wheel to identify the faulty shock absorber; 4. Replace the faulty shock absorber. The Baojun 730 is a 5-door, 7-seat MPV with body dimensions of 4780mm in length, 1780mm in width, and 1740mm in height, with a wheelbase of 2750mm. It is equipped with a 1.5T turbocharged engine and a 6-speed manual transmission, delivering a maximum power of 108 kW and a maximum torque of 250 Nm. The drive system is front-wheel drive, with a MacPherson strut independent front suspension and a torsion beam non-independent rear suspension.
I often experience squeaking noises when driving my Baojun 730 over speed bumps, which is particularly annoying. At first, I thought it was the tires slipping, but upon closer observation, I noticed the noise was more pronounced when going over potholes. I took it to a repair shop, and the mechanic checked it, saying the front suspension shock absorbers were worn out and some chassis screws were loose. I tried tightening the screws at home with a wrench, and the noise reduced significantly, but to completely eliminate it, I had to replace the shock absorbers. After installing new parts, the problem was resolved. Now, I slow down when driving over speed bumps to reduce such wear. I recommend trying to tighten the screws first; if that doesn’t work, take it to a professional shop promptly to avoid compromising driving safety.
