FRONT AXLE - Continued
(11) Check bearing preload using a spring scale,
calibrated in lbs or N (100 lb or 500 N
capacity), as shown. A preload of 38 - 42
lb or 170 - 185 N should be measured after
ball socket starts moving.
(12) Add or delete shims if bearing preload is
different from specified range. Repeat
steps 11 and 12 until correct preload is
It is recommended that at least one shim
be installed in both upper and lower
positions. In some instances, it might
be necessary to grind or machine the
ball socket cover surfaces to achieve
(13) With ball adjusted as required, fill the cavity
between ball and socket with grease (item
16, Appendix B).
(14) Preassemble ball seals and seal retainers
(2). Use a vise to hold retainer halves
together in a circle while installing seals.
Be sure gaps between seals and between
retainers do not coincide (see illustration).
Trim or cut off excess seal material at a
slight angle to ensure that the seal ends
(15) Install seals and retainers on ball socket as
shown. Insert retainer gaskets between
retainer halves. Tighten retainers to ball
socket using capscrews and lockwasher(1).
Tighten capscrews to 170 ft lb (230 Nm).
(16) Coat exposed area of axle ball with a thin
film of grease (item 16, Appendix B).
