2. Bearings—Front Wheel
Lubricate front wheel bearings as scheduled using a
high quality wheel bearing lubricant (see Recommended
Fluids and Lubricants chart). Be sure to force grease
between rollers. Check the bearing races for signs of
pitting, brinelling or overheating. Wipe the spindle clean
and apply a small amount of grease to prevent rust.
Wipe the wheel hub clean and apply a small amount of
grease inside the hub.
CAUTION: Do not overfill the wheel hub. Too much
grease can cause overheating and bearing damage, or it
can leak and contaminate brakelinings.
Install the inner bearing and a new grease seal. As
semble the hub assembly and adjust bearings as de
scribed in Chapter 2F—Axles and Front Hubs.
Inspect bearings, and clean and repack if necessary,
when they are removed for other services.
Manual Locking Hubs
Inspect and lubricate manual locking hubs as sched
uled using chassis lubricant. For a more detailed pro
cedure, refer to Chapter 2F—Axles and Front Hubs.
Brake and Chassis Inspection
Brakes
Inspect linings for wear, cracks, charred surfaces or
broken rivets, and for contamination by brake fluid, axle
lubricant or other contaminants. Refer to the following
inspection procedures.
MAINTENANCE B-9
Front Brakelinings—CJ and Scrambler Models
Check both ends of the outboard lining by looking in
at each end of the caliper (fig. B-9). These are the points
at which the highest rate of wear normally occurs. At
the same time, check the lining thickness of the inboard
shoe to make sure that it has not worn prematurely.
Look through the inspection port to view the inboard
shoe and lining. Whenever the thickness of any lining is
worn to the approximate thickness of the metal shoe, all
shoe and lining assemblies on both brakes should be
replaced.
Fig. B-9 Disc Brake Assembly—CJ and Scrambler Models
Front Brakelinings—Cherokee-Wagoneer-Truck Models
Check brakelining thickness through caliper in
spection port (fig. B-10).
A wear sensor is attached to the brakeshoes. When
brakelining wears to the point that replacement is nec
essary, the sensor contacts the disc, making a screeching
or scraping noise to warn the driver that brakeshoes
need replacement.
Rear Brakelinings—All Models
Replace linings worn to within 1/32 inch (.78 mm) of
rivet head.
Rear Self-Adjusting Mechanism
Operate the adjuster cable (CJ) or adjuster lever and
pivot (Cherokee, Wagoneer and Truck). Check for ease of
operation of the adjuster screw assembly. Check condi
tion of the adjuster components for bending, frayed
cables, loose or overheated springs, or binding.
