What Causes the Clicking Sound When Turning the Steering Wheel of Baojun 730?
3 Answers
The causes of abnormal noise from the steering gear include: insufficient lubrication of the steering column leading to high friction, low power steering fluid, issues with the universal joint, aging and hardening of the rubber bushings in the suspension stabilizer bar links, and damage to the plain bearing. Here are the relevant explanations: 1. From the perspective of steering gear mechanics: Many vehicles now feature vacuum assist, which only reduces the driver's steering effort without changing the actual load on the steering gear. Therefore, an effective way to minimize steering gear wear is to reduce the operational load on the steering gear. 2. Aging, leading to safety hazards: Turning the steering wheel after the wheels have started moving reduces the friction resistance between the tires and the ground, alleviating excessive load on the steering gear and over-wear of the steering linkage system, which can cause abnormal noises when turning. 3. Long-term stationary steering: This not only places a significant load on the steering gear but also accelerates tire surface wear, shortening the tire's service life.
I also experienced a creaking sound when turning the steering wheel with my Baojun 730 before. It's mostly due to aging steering system issues, such as loose steering linkage ball joints or increased internal clearance in the steering gear, causing friction noise when the tires rotate. You can do a simple check yourself: after parking the car securely, gently shake the steering wheel to listen for the source of the sound. If it's coming from the wheel axle, it might be due to worn ball joints or loose linkage. If not repaired promptly, the steering will become increasingly heavy, and steering wheel vibration at high speeds can be very dangerous. It's best to go to a professional shop as soon as possible for inspection and part replacement to avoid accidents. For regular maintenance, pay attention to periodically checking the steering fluid and lubrication points, as parts on this car tend to wear out after a few years of driving.
Common causes of steering wheel knocking noise in the Baojun 730 include: wear in the steering gear creating gaps, or damaged suspension top mounts transmitting vibrations to the steering column. During inspection, pay special attention to the resistance when turning the steering wheel. If the noise occurs with slight steering input, it may be related to the power steering pump's electrical circuit. From my personal experience with car maintenance, prolonged driving on bumpy roads accelerates bushing wear, and replacing them with new parts eliminated the noise. It's advisable to use a multimeter to check voltage and ensure proper power supply, preventing more severe steering failures. Developing a habit of pre-drive inspections helps detect issues early.
