. Be careful notto damagethe balljoint bootwhen
installing the knuckle.. Tighten all mounting hardware to the specified
lOrque values.. Torque the castle nut to the lower torque
specification, then tighten it only far enough to
align the slot with the ball joint pin hole. Do not
align the castle nut by loosening it.
. Install a new look pin on the castle nut after
torquing.. Use a new spindle nut on reassembly.. Before installing the spindle nut, apply a small
amount of engine oil to the seating surface of the
nut. After tightening, use a drift to stake the
spindle nut shoulder against the driveshaft.
. Before installlng the brake disc, clean the mating
surface of the front hub and the inside of the
brake disc.. Before installing the wheel, clean the mating
su rface of the brake disc and the inside of the
wneet.. Check the front wheel alignment, and adjust it if
