WARNING
7.2.10 Wheel Rims
If the trailer has been struck, or impacted, on or near the wheels, or if the trailer has struck a
curb, inspect the rims for damage (i.e. being out of round or bent or cracked); and replace any
damaged wheel. Inspect the wheels for damage every year, even if no obvious impact has
occurred.
7.2.11 Wheels, Bearing and Lug Nuts
A loose, worn or damaged wheel bearing is the most common cause of brakes that grab.
To check your bearings, block the tires that you are not checking, jack the trailer up and check
the wheels for side-to-side looseness. If the wheels are loose, or spin with a wobble, the
bearings must be serviced or replaced.
Most trailer axles are built with sealed bearings that are not serviceable. Sealed bearings must
be replaced as complete units.
7.2.11.1
Unsealed Bearing (Hubs)
If your trailer has unsealed axle bearings, they must be inspected and lubricated once a year or
12,000 miles to insure safe operation of your trailer.
If a trailer wheel bearing is immersed in water, it must be replaced.
If your trailer has not been used for an extended amount of time, have the bearings inspected
and packed more frequently, at least every six months and prior to use.
Follow the steps below to disassemble and service the UNSEALED wheel bearings.
•
After removing the grease cap, cotter pin, spindle nut and spindle washer, remove the
hub and drum to inspect the bearings for wear and damage.
•
Replace the bearings that have flat spots on the rollers, broken roller cages, rust or
pitting. Always replace bearings and cups in sets. The inner and outer bearings are to
be replaced at the same time.
•
Replace the seals that have nicks, tears or wear.
•
Lubricate the bearing with a high quality EP-2 automotive wheel bearing grease.
Every time the wheel hub is removed and the bearings are reassembled, follow the steps below
to check the wheel bearings for free running and adjustment.
Worn or damaged or under-inflated tires can cause loss of control, resulting in
serious injury and possibly death.
Inspect tires before each tow.
