Col­laps­ing front wheel bear­ing

Car Mechanics (UK) - - Tales From The Workshop -

We of­ten see dra­matic fail­ures of com­po­nents, even though own­ers are only slightly aware of the prob­lem. The driver of this 2004 Vaux­hall Combo van was only con­cerned by a slight squeal from the front of the ve­hi­cle. Our first re­ac­tion on see­ing the wear on the front tyre was that some­thing – most likely a front wheel bear­ing – had failed. Jack­ing up the ve­hi­cle re­vealed that the wheel was flop­ping about and the hub bear­ing had in­deed col­lapsed.

There was lit­tle doubt that the dam­age done was go­ing to ex­tend to the hub and that it was highly likely that the bear­ing had worn so badly that it had col­lapsed and spun on the hub. This was the case and, due to the age of the van, the owner opted to pick up a re­place­ment unit from a break­ers.

The re­place­ment was quite eas­ily fit­ted, af­ter which a new tyre was also needed. Back on the road, the owner re­marked that the steer­ing now felt more pos­i­tive.

As well as the worn tyre, col­lapsed bear­ing and ru­ined hub, dam­age had also oc­curred to the brake disc.
