Can the Steering Gear Assembly Be Repaired?
2 Answers
Steering gear assembly can be repaired. The handling of steering gear failures requires targeted measures based on the cause of the malfunction. Damage to the steering gear can lead to difficulty in steering and, in severe cases, complete inability to steer. If damage occurs, it should be replaced promptly. Below are the causes of steering gear failures and their solutions: Steering Gear Malfunction: If inspection reveals low hydraulic pressure in the steering gear assist system, it indicates that the heavy steering is caused by the steering gear. Most steering gear failures are due to piston or cylinder scoring or damage to the piston seal rings, which allows fluid to pass between the two chambers, preventing effective buildup of assist pressure. Solution: Have it repaired by a professional manufacturer. Power Steering Pump Failure: When testing shows that the pump pressure of the power steering pump does not meet the standard value, it is clear that the heavy steering is related to this issue. Solution: Check the mating surface of the flow control valve and valve seat, and whether the safety valve ball is not sealing properly. Address any issues promptly. Clogged Return Oil Filter in the Reservoir: Long-term lack of maintenance or replacement of the return oil filter in the reservoir can cause clogging, hindering the circulation of power steering fluid and increasing the backpressure of the return oil, which also results in heavy steering. Solution: Clean or replace the return oil filter in the reservoir promptly.
The steering gear assembly is definitely repairable. I've been driving for over a decade and have fixed minor issues with the steering gear several times. Common problems like oil leakage from the steering gear are mostly caused by aging seals, and replacing them with new ones is sufficient, usually costing just a few hundred yuan. If internal gear wear causes the steering wheel to stick when turning, adjusting the gear clearance can solve the issue. However, if internal components are completely damaged, such as broken gears, repair might not be cost-effective since problems may recur after fixing. It's safer to replace the entire assembly in such cases. The repair process requires professional tools and skills, so don't attempt it yourself—improper installation could compromise steering safety. It's best to detect and address issues early, such as checking for unusual noises or heavier steering while driving. Regularly monitoring the power steering fluid condition can also extend the steering gear's lifespan. Overall, repairing minor issues is worthwhile, being both cost-effective and environmentally friendly.
