Dismantling and rebuilding the assembly requires a press and appropriate tubular spacers, which are not always available, however, large bench vice and a substitute spacer such as large sockets can be used. The inner races will be tight on the hub flange and should the inner race not be detached when pressed out, a knife-edged bearing puller will be required to remove the race. The first step is to take off the rear hub carrier and then firmly hold it in place and carefully press the hub flange out of the bearing centre. When the inside race remains on the flange, a knife-edge bearing puller may be used to take it off. The next step is to remove the hub bearing retaining circlip of the hub carrier, hold the hub carrier in place and press the hub bearing out with an appropriate tubular spacer. Clean the hub carrier bear good and tip out all the dirt and grease, polish all burrs or raised edges that may hinder reassembly, and replace the circlip in case of doubt of its condition. When reassembling, use a small amount of clean engine oil on the outer race of the bearing so that it can be easy to install. Install the bearing in the hub carrier and press completely in place and makes sure it drops into place squarely with an appropriate tubular spacer that touches the outside race of the bearing only. Bearing: place the bearing and have it properly positioned in the carrier groove of the hub. Last, hold the bearing inner race and fully press the hub flange into the bearing, ensure that it turns freely and then re-fit the rear carrier of the hub.
