With the right supplies and parts, it is possible to change a wheel bearing as a do-it-yourself project. However, the level of difficulty and the tools required usually necessitate allowing a professional mechanic to handle the job instead. For example, a jack and a pair of jack stands are needed.
Other items needed for changing a wheel bearing include Channelocks, an adjustable wrench, a bearing race driver tool, a socket and ratchet set and wheel blocks. New wheel bearings, a new cotter pin, grease seals and wheel bearing grease are also needed. Instructions online walk novice mechanics through the process of changing wheel bearings once all tools and supplies are obtained. For instance, About.com offers a four-page tutorial.
