CAUTION
You must follow the maintenance procedures to prevent
damage to important structural components. Damage to
certain structural components such as wheel bearings
can cause the wheel end to come off of the axle. Loss of
a wheel end while the trailer is moving can cause you to
lose control and lead to an accident, which can result in
serious injury or death.
2. Remove the wheel.
3. Remove the grease cap by carefully prying progressively
around the flange of the cap. If the hub is an oil lube type,
then the cap can be removed by unscrewing it
counterclockwise while holding the hub stationary.
4. Remove the cotter pin from the spindle nut.
For E-Z Lube® axles produced after February 2002, a new
type of retainer is used. Gently pry off retainer from the nut
and set aside.
5. Unscrew the spindle nut (counterclockwise) and remove
the spindle washer.
6. Remove the hub from the spindle, being careful not to allow
the outer bearing cone to fall out. The inner bearing cone
will be retained by the seal.
7. For 7,200 lb. and 8,000 lb. axles, a hub puller may be
necessary to assist in drum removal.
Brake Drum Inspection
There are two areas of the brake drum that are subject to wear
and require periodic inspection. These two areas are the drum
surface where the brake shoes make contact during stopping and
the armature surface where the magnet contacts (only in electric
brakes).
The drum surface should be inspected for excessive wear or
heavy scoring. If worn more than .020" oversized, or the drum
has worn out of round by more than .015", then the drum surface
should be re-machined. If scoring or other wear is greater than
