How to Handle Difficult Steering in Vehicles with Power Steering?
2 Answers
Driving a vehicle with power steering that has difficulty steering should be taken to a repair station for maintenance. Below are the relevant details for checking the power system: 1. Steering gear inspection items: (1) Mechanical steering gear inspection: Check for wear and damage on the steering pinion and rack, and for cracks on the steering gear housing. Note that parts on the steering gear must not be welded or straightened; they can only be replaced. Also, inspect the wear and damage on bearings and bushings, as well as the wear and aging of oil seals and dust covers, and replace them promptly. (2) Steering damper inspection items: Check the stroke of the steering damper. The working stroke L should be the difference between the maximum length (Lmax) of 556mm and the minimum length (Lmin) of 344.5mm, which is 211.5mm. Replace if the stroke is insufficient. Check the damping force of the steering damper; the maximum damping load is 560N, and the minimum damping load is 180N (conducted on a test bench). Check if the support of the steering damper is cracked. Inspect the rubber bushings at the ends of the steering damper for damage and aging. 2. Power steering gear inspection method: Check all oil leakage points and replace all O-rings and gaskets. If there is an issue with the hydraulic distribution valve, it must be replaced entirely or the sealing rings on the distribution valve must be replaced. Check if the pinion and rack are damaged. Inspect bearings and oil seals for damage. Check the dust cover for damage and aging. Examine the steering gear housing for cracks and oil leaks.
I've been driving for twenty years and have encountered steering difficulties several times. Common causes include insufficient power steering fluid or pump failure. Once on a suburban road, the steering wheel suddenly became heavy. I immediately slowed down and pulled over, opened the hood to check the fluid reservoir, and found the level below the minimum line. Adding the specialized fluid solved the problem. If the issue persists after adding fluid, it might be a faulty pump or a loose belt, often accompanied by a whining sound. Avoid forcing the drive, as it can lead to loss of control and accidents—safety first. I've developed a habit of checking the fluid level and belt condition monthly and replacing the steering fluid every two years to prevent major issues. Remember, small oversights can lead to big troubles. Addressing problems promptly saves both money and hassle compared to procrastination. If you're unsure, always consult a professional mechanic for diagnosis and repair.
