Why does the rear wheel bearing of Camry make abnormal noise?
2 Answers
Camry rear wheel bearing abnormal noise is caused by aging vehicle parts. The following are detailed explanations and solutions: 1. Insufficient gear oil or decreased viscosity: Solution: Improve by changing oil, replenish sufficient oil quantity or switch from multi-grade oil to single-grade oil, or use oil with higher viscosity grade. If caused by mechanical failure, professional repair is required. 2. Improper adjustment of main reducer gear clearance: Solution: Adjust by moving the positions of driving and driven bevel gears. This can be achieved by increasing or decreasing the number of adjusting shims installed between the reducer housing and the driving bevel gear bearing seat (i.e., moving the position of driving bevel gear). 3. Excessive gear wear or damage: Solution: Repair using nano-polymer technology. Polymer nano-materials have excellent adhesion, compression resistance and comprehensive performance in repairing transmission parts wear, enabling quick online repair without disassembly or machining, effectively repairing shaft wear.
I used to drive a Camry, and during long-distance trips, the rear wheels would make a humming noise, which was quite annoying. I looked into it and found that it might be due to excessive bearing wear, especially after prolonged use at high mileage, where the ball gap increases and creates noise. The issue becomes more noticeable with poor tire conditions or high-speed turns. Additionally, dried-up grease or contaminants getting inside can worsen the problem. Later, I had a friend check it and discovered that the bearing shell seal was faulty. Replacing it made a big difference. Regular maintenance, including checking the wheel hubs and related brake system components, can help prevent such noises. Get it fixed as soon as possible—don’t delay until it becomes a bigger issue. If left unattended, the wheel could seize up, which is extremely dangerous and more costly to repair.
