Final answer:
Technician A suggests checking brake components while Technician B recommends checking the differential breather to address fluid leakage from an axle seal.
Step-by-step explanation:
The subject of this question is Automotive Technology since it focuses on troubleshooting a specific issue related to fluid leakage from an axle seal.
To address the issue, Technician A suggests removing the wheel and checking for incorrectly installed brake components. This is important because incorrectly installed brake components can lead to the leakage of fluid from the axle seal.
Technician B recommends checking for obstructions at the differential breather. The differential breather is a component that allows for the equalization of pressure within the axle assembly. Blockages in the breather can cause pressure build-up, leading to fluid leakage from the axle seal.
