RE: Wheel Bearing Removal - 1999 GT
This year Mustang GT does not use a castle nut and cotter pin. Haynes and other automotive books do not provide information for the type of setup. What actually is designed is a multiple nut configuration with what appears to be a C channel wrapped around the outage edge of the Nut(s). The channel actual holds the nuts together as one unit. To remove the arrangement you need a 36mm socket and a lot of muscle. Once you pull the nut, the whole bearing/hub assembles pulls off...it is one non serviceable unit. Cost about $55-$80 depending on the brand. When you put the unit back on, Ford says to torque it to 258 ft-lbs.
