6.
Install lower cover (5) without shims and install
and tighten two opposite bolts (6) to a torque of
5.7 N.m (50 lb. in.).
7.
Use a feeler gauge to check the gap between
the cover and knuckle (1) at each bolt location.
8.
Find the average of the two measurements and
subtract 0.10 mm (.004 in.) from this average.
This is the thickness of shims (7) that must be
installed between lower cover (5) and the
steering knuckle.

9.
Remove the cover, install the shims, install
cover (5) and the bolts. To check the preload
adjustment of the bearings, use the procedure
that follows:
1.
Put a pound-inch torque wrench on one of the
upper cover bolts so that the handle of the
wrench is angle (A) 900 from the center of the
bolt directly opposite the bolt that the torque
wrench is on.
2.
Check the torque required to turn the steering
knuckle.
NOTE: The steer wheel and steering link must be
removed before the check is made.
3.
The indication must be 4.5 to 6.8 Nm(40 to 60
lb. in.). If the indication is too high, add shims
between the lower cover and knuckle. If the
indication is too low, shims must be removed.
