Note: There are two types of bolts used to
secure the rear hub carrier to the lower arm
(see illustration). The two types of bolt must
not be mixed on a vehicle, but can be changed
in complete sets for the alternative type. A
complete set is eight bolts, four each side.
Note that the two types of bolt have different
torque wrench settings. When renewing the
wheel bearings a suitable puller will be
required to remove the drive flange, and a new
rear hub nut must be used on reassembly.
