Final answer:
The high-pitch squeal when steering is turned full lock could be caused by low power steering fluid, a loose or worn-out belt, or a faulty power steering pump.
Step-by-step explanation:
Cause of High-Pitch Squeal when Steering is Turned Full Lock
A high-pitch squeal when steering is turned full lock can be caused by a few different factors:
- Power steering fluid level: If the power steering fluid is low, it can cause the power steering pump to make noise, including a high-pitch squeal. Check the fluid level and add more if needed.
- Belt tension: A loose or worn-out belt could be slipping when the steering is turned full lock, causing a high-pitch squeal. Inspect the belt for signs of wear or looseness and tighten or replace as necessary.
- Faulty power steering pump: In some cases, the power steering pump itself may be damaged or faulty, causing it to make noise when the steering is turned to the full lock position. If the fluid level and belt tension are good, the pump may need to be replaced.
If none of these solutions solve the issue, it is recommended to have a professional mechanic inspect and diagnose the problem.
