maintenance (comparable to a truck setting on a DRMO or GSA lot
awaiting sale) meant that all the critical systems were now in an
unknown state. Hence, the team at Memphis Equipment performing
the repairs elected to pull the axles and hubs, allowing inspection
not only of the brakes, but also the wheel bearings. Here, the
capscrews securing the axle shafts are being removed.
After straightening the bent-over portion of the adjusting lock nut,
the outer wheel bearing adjusting nut can be removed, as seen
here. The same wrench is used to remove the inner adjusting nut.
This is followed by removing the outer bearing seal (rear axles
only), the outer bearing cones, and at last the hub and drum
assembly. The oil stains visible on the hub are evidence of
forthcoming problems.
