1. Strange Noises: Listen for any unusual noises coming from the rear of the ATV while riding or when rotating the wheels by hand. A worn or damaged rear axle can produce grinding, screeching, or knocking sounds.
2. Stiff or Uneven Rotation: Check if the rear wheels rotate smoothly and evenly. If you feel any resistance or a clicking sensation when rotating the wheels, it could be a sign of axle issues.
3. Axle Play: Inspect the rear axle for any excessive play or movement. There should be minimal movement (if any) when you try to move the axle up, down, or sideways.
4. Bent Axle: If the rear axle is visibly bent or misaligned, it can cause problems with the transmission of power and proper functioning of the ATV.
5. Transmission Problems: Issues with the rear axle can affect the transmission of power to the rear wheels. If you experience sudden loss of power or decreased acceleration while riding, it's worth checking the rear axle.
6. Vibration: Excessive vibrations coming from the rear of the ATV, particularly when accelerating, can be another indication of rear axle problems.
7. Leaking or Grease Problems: If you notice leaks or issues with the grease around the rear axle, it could be a sign of damage or insufficient lubrication.
8. Difficulty in Steering or Turning: A damaged or worn axle can affect steering and turning ability. If you experience difficulties in controlling the ATV's direction, it might be related to the rear axle.
9. Visual Damage: Look for any visible damage to the rear axle, such as cracks or breaks, which can weaken its integrity.
10. Tire Wear: Premature or uneven tire wear on the rear wheels can sometimes be caused by rear axle problems, especially if it's accompanied by other symptoms.
11. Loss of Power: If the rear axle breaks or is severely damaged, the power transmission to the rear wheels will be affected, resulting in a loss of power or complete immobilization of the ATV.
12. Resistance When Riding: You may feel resistance or discomfort when riding the ATV, especially when accelerating or going over rough terrain.
If you suspect that the rear axle of your Yamaha 350 ATV may be damaged, it's important to have it inspected by a professional to confirm the issue and get the necessary repairs or replacements done.
