What method does Tech A suggest for removing differential bearings?

The method most commonly recommended for removing differential bearings is using a hydraulic press. A hydraulic press provides the appropriate amount of force needed to safely and effectively remove bearings without damaging the surrounding components. This technique ensures that the bearings are removed straight and cleanly, minimizing the risk of damage to the differential housing or the bearings themselves.

Using a rawhide hammer may seem plausible as it is a softer tool that can prevent damage to some components. However, it lacks the precision and control provided by a hydraulic press, which could lead to uneven forces being applied, potentially damaging the bearings or housing.

Overall, the hydraulic press is the preferred method for this task, offering a combination of safety and effectiveness. The other available methods do not provide the same level of reliability for bearing removal.
