Replacement of Knuckle Assembly
NOTE: In the event that knuckles are
received with the sockets and snap ring
assembled, along with the bottom torque
prevailing nut, top castilation nut, split sleeve
and cotter key, it is recommended that after
all of the old parts are removed from the
yoke, the steps listed below are to be followed
for assembly of the knuckle to the yoke:
1. Assemble knuckle to yoke. Assemble bottom torque
prevailing nut. Torque nut to 70-90 ft. lbs.
NOTE: If the stud turns while attempting to
torque this nut, assemble the top nut and
tighten till it is snug. This will pull the
bottom stud into the tapered hole of the yoke
and will prevent it from turning while
torquing up the nut. After you have applied
the 70-90 ft. lbs. Only use this method when
necessary.
2. Remove the top nut.
