What are the causes of Lexus power steering system failure?
1 Answers
The causes of Lexus power steering system failure are as follows: loose oil pump V-belt, low oil level in the reservoir, insufficient oil pump pressure, stuck pressure control, excessive external leakage, excessive internal leakage, too tight steering shaft bushing, deformed front suspension, and air in the hydraulic system. Troubleshooting methods: 1. Check the condition of the steering oil pump drive: Press down on the drive belt of the steering oil pump by hand. If the pressing amount is too large, it indicates that the drive belt is too tight and needs adjustment. Start the engine and let it idle. Suddenly increase the engine speed and check if the steering oil pump drive belt slips. If slipping occurs, it indicates that the drive belt is too loose or excessively worn and should be adjusted or replaced. 2. Check the oil level in the steering fluid reservoir: If the steering fluid level is at or below the "MIN" line, it indicates insufficient steering fluid, which should be added to the specified level. 3. Check the filter in the steering fluid reservoir: Remove the filter and observe its condition. If the filter is found to be excessively dirty, it indicates clogging and should be cleaned; if the filter is found to be broken, it should be replaced.
