Technical Tips: Are your hub bearings located correctly?

The front hubs on pre-war cars are located on the axle by the outboard bearing and as a result this has to do a lot of work. It is important that this is fitted correctly.

The grease cap and its retaining nut keep the bearing in position, and it is most important that this clamps the bearing tightly when fitted. If the hub is refitted by tapping on the outer rim of the hub the bearing will tend to 'walk' out of the hub, and may not be pulled back in by the grease cap and ring nut.

Instead, use a short length of tube passed over the end of the stub axle up against the inner race of the bearing, and tap on this to fit the hub. The bearing will then stay in place. It is also better for the bearing, which otherwise might be harmed when tapping on the hub to fit it.
