Final answer:

Technician A is correct regarding the dust cap mounting hole, while Technician B is incorrect about axle replacement.

Step-by-step explanation:

Technician A is correct. If the dust cap mounting hole is out of round, it means that the hole is not perfectly circular and may cause a loose fit between the hub and the dust cap. This can result in the dust cap not sealing properly and allowing contaminants to enter the hub assembly. In such cases, replacing the hub is necessary to ensure a secure fit and prevent further damage.

On the other hand, Technician B is incorrect. If damage or cross-threading is found on the spindle threads, it does not automatically require the replacement of the axle. In some cases, it may be possible to repair or replace just the damaged spindle, rather than the entire axle assembly. However, if the damage is severe or extends beyond the spindle threads, it may be necessary to replace the entire axle.
