Which repair method is suitable for fixing a toe-in condition without component replacement?

Using spacers at the scissor torque links is an effective method for addressing a toe-in condition without needing to replace any components. The toe-in condition refers to the alignment of the wheels, specifically that the front edges of the wheels are closer together than the rear edges. This misalignment can lead to uneven tire wear and handling issues.

By introducing spacers at the scissor torque links, you can effectively adjust the angle of the landing gear, allowing for a correction in the toe alignment. This method enables precise adjustment without the need to replace parts, making it a cost-effective and efficient solution.

The other methods listed do not directly relate to correcting a toe-in condition. Adjusting the wheel bearing and re-torquing the wheels are general maintenance practices that may contribute to overall wheel stability but do not specifically address alignment issues. Changing brake fluid has no relevance to wheel alignment at all, as it pertains to the braking system rather than the geometry of the landing gear.
