DANGER
Always use the correct socket wrench when removing the
adjusting nut. Do not attempt to loosen an adjusting nut by
striking it with a hammer. Do not place a chisel or drift next to
the adjusting nut and strike the chisel with a hammer. Damage
to the adjusting nut can result, which can prevent obtaining
the correct wheel bearing adjustment during reassembly. An
incorrect adjustment can cause a wheel to separate from the
vehicle during operation. Death or serious personal injury and
damage to components can result.
5. Remove the jam nut, lock washer and the inner adjusting
nut from the spindle. Figure 4.8. Use a 4-7/8-inch socket
wrench to remove the adjusting nut. Figure 4.9.
