What are the reasons for the frequent failure of the Baojun 730 steering gear?
4 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.
I work in auto repair and have dealt with many cases of frequent failure in the Baojun 730 steering gear. Common causes include clogged or failed power steering pump oil circuits leading to insufficient assistance—this model's pump has unstable quality. Additionally, the steering gearbox wears out quickly internally, possibly due to subpar OEM part materials. Poor electrical contacts can also trigger EPS faults; for example, steering assist automatically fails when the speed sensor malfunctions. Oil seal leaks are extremely common—once the fluid drains, the gears grind dry. I recommend owners regularly check power steering fluid levels and inspect the steering system quarterly. Avoid high-speed driving over potholes daily to minimize impact. Address issues early—replacing components promptly generally extends longevity.
I've owned a Baojun 730 for just two years, but the steering gear has already failed twice—what a headache. The reasons probably come down to poor driving habits. For instance, I often turn the steering wheel while stationary, which increases the load and causes premature wear on components. Inadequate maintenance is also a major factor; infrequent power steering fluid changes lead to increased friction. Additionally, there might be defects in the original parts, such as the power steering pump or seals aging too quickly. During one repair, I discovered the lubricant had dried up, and the gears had rusted. Now I've learned my lesson: I drive more smoothly, avoiding sudden steering movements, and make regular visits to the 4S shop for lubrication. These small habits can prevent repeated repairs, saving both time and money.
