Axle Inspection & Repairs; Removal Of Hub; Bearing/Seal Inspection And Replacement - Four winns Horizon Owner's Manual

Four Winns uses the Accu-Lube™ bearing protection
system on its trailers. The Accu-Lube™ design is sub-
mersible and provides for grease flow that completely
repacks and protects the bearings. This lubrication
system disallows water entry, thus extending the life of
the bearings, spindle and hub.
Lubricate the bearings as follows:
1. Remove the rubber plug.
2. Insert the grease gun into the grease fitting. Pump
grease until old grease comes back out the front.
3. Remove old grease and reinstall rubber plug.
NOTICE
Most bearing failures are due to improper main-
tenance. Be sure to inspect bearings and seals
as noted in Section R-6B and refer to the
manufacturer’s literature included with your
trailer.

4. Remove cotter pin.
5. Unscrew the spindle nut counter clockwise.
6. Remove spindle washer.
7. Remove hub from spindle.
B. Bearing/Seal Inspection and Replacement
When inspecting bearings or seals:
1. Inspect the grease seal for damage, tears, or cracks.
If there is no damage or leakage in not occurring,
the seal is in good condition.
If the seal is torn or cracked, then it should be re-
placed. The seal can be pried out of the hub with a
screw driver. Be sure to replace the seal using the
recommended replacement parts. Parts can be
obtained from your Four Winns dealer.
2. When inspecting the bearing, check for corrosion
and wear. If any rust or wear exists on the bearing,
then remove and replace with the recommended
parts listed in the table above.
3. If the bearings are in good condition, repacking the
grease should be done at this time. Hand pack each
bearing individually using a premium water resis-
tant wheel bearing grease.
