What are the reasons for the frequent failure of the Baojun 730 steering gear?
2 Answers
The reasons for the failure of the Baojun 730 steering gear include: lack of lubrication in the steering column, resulting in high friction; insufficient power steering fluid; issues with the universal joint; aging and hardening of the rubber bushings on the chassis suspension stabilizer bar links; and failure of the plane bearing, among others. Below is additional information: 1. The structure of the power steering system is very complex and generally cannot be repaired by non-professionals. With proper maintenance, it is less likely to fail. Regularly check the fluid level in the reservoir, ensuring it does not fall below the lower mark on the dipstick. If the power steering system runs out of fluid, the pressure pump may be damaged. It is essential to change the fluid periodically and avoid turning the steering wheel to its extreme limits. 2. The power steering system consists of a mechanical steering system augmented with a power assist unit. The steering pump is mounted on the engine and driven by the crankshaft via a belt, supplying hydraulic fluid. The steering fluid reservoir has inlet and outlet pipe connections, linked to the steering pump and control valve via hoses. The steering control valve is used to alter the fluid pathways.
I've been driving the Baojun 730 for several years and find the frequent failure of the steering gear quite annoying. The main issue lies in some inherent design flaws. The Baojun 730 uses a mechanical hydraulic power steering system that's prone to problems, such as insufficient pressure when the power steering pump wears out, making steering particularly heavy. Additionally, poor oil seal performance is a common issue—leakage affects the entire system, requiring frequent fluid top-ups. Moreover, the gear set has relatively low machining precision, leading to faster wear when frequently driven on bumpy roads. I recommend avoiding excessive stationary steering, as this puts extra stress on the steering gear. Regular maintenance is crucial—check the power steering fluid and component lubrication every six months to extend its lifespan. If you notice abnormal steering wheel noises or slow return, visit a repair shop immediately to prevent major issues.
