How to Eliminate the Power Steering Malfunction in Malibu?
1 Answers
If the Malibu displays a power steering malfunction warning, it indicates a fault in the vehicle's power steering system that requires immediate inspection and repair. Common issues include abnormal noises during steering, steering gear oil leakage, and weakened automatic return function. Please visit a 4S shop for diagnosis and repair; the fault can be automatically cleared once resolved. Additional Information: Common faults and causes in vehicle steering systems include: 1. Abnormal noises during steering are typically mechanical issues, such as damage to the kingpin and bushing or failure of the column thrust bearing. During inspection, turn the steering wheel left and right to locate the noise source for disassembly and repair. 2. Steering gear oil leakage usually occurs at the steering gear cover, side cover, or the connection between the steering shaft and the pitman arm. These areas have seals, and replacing the oil seals and gaskets can resolve the issue. Leakage in other areas may indicate casting defects or cracks in the steering gear housing. Minor cracks and defects can be sealed with Loctite 290 high-penetration sealant. 3. Most vehicles feature an automatic return function for the steering wheel. In hydraulic-assisted vehicles, this function may weaken due to hydraulic damping but should still retain some capability. If returning the steering wheel requires the same effort as turning it, the return function is faulty, typically due to mechanical issues in the steering system.
