What are the reasons for a heavy steering wheel in the Teana?
2 Answers
The reasons for a heavy steering wheel in the Teana are as follows: Power steering pump failure: When the pump pressure of the power steering pump fails to meet the standard value, the steering wheel will feel heavy during use. It is necessary to inspect the flow control valve. If there is leakage in the flow control valve or safety valve during driving, it can be repaired by grinding. Then, check whether the spring of the safety valve has failed. Steering gear failure: When the hydraulic pressure of the steering gear is low, the steering will feel heavy. If the steering wheel becomes heavy due to the hydraulic pressure of the steering gear, it is necessary to seek professional repair from a specialized manufacturer. It is not recommended for the car owner to handle it themselves. Lack of oil or air in the power steering system: When there is air in the car's steering system, not only will the steering feel heavy, but there will also be noise during steering. This needs to be addressed promptly to avoid greater losses. Clogged return oil filter in the oil reservoir: If the return oil filter in the oil reservoir is not maintained or replaced for a long time, it can easily become clogged, leading to poor circulation of the power steering oil and a heavy steering wheel.
As someone who has been repairing cars for decades, I've encountered many cases where the steering wheel of a Teana becomes heavy, most commonly due to issues with the power steering system. The Teana comes with either hydraulic or electric power steering. For hydraulic systems, insufficient power steering fluid, a worn-out pump, or leaking hoses can cause the power assist to fail. In electric systems, motor overheating, sensor malfunctions, or control module damage can all lead to system failure, naturally making the steering wheel heavy. Low tire pressure is also often overlooked, as insufficient pressure increases steering resistance. Additionally, incorrect wheel alignment or worn chassis components, such as aging tie rods, can affect handling. Ignoring these issues can increase the burden on the chassis and raise repair costs. I recommend that drivers check tire pressure and power steering fluid first if they notice heaviness, and visit a professional shop for diagnosis as soon as possible. The Teana's steering system is durable but requires regular maintenance. I've handled many similar cases, and timely intervention is crucial for safety.
