88 bronco 11 how to install front wheel bearings an race seals

This is a question that is covered in detail and with pictures in a Chilton's Manual, available at any auto parts store. There are too many steps and important torque specifications to summarize in an online reply to this question. Especially important is the fact that wheel bearings need to be "pre-loaded" with a certain torque before installation is finished or failure can result. A manual will walk you through this repair and give you a better idea if you feel mechanically and tool-equipped to handle it.
