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 is not
occurring, the seal is in good condition.
If the seal is torn or cracked, then it should be
replaced. 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 bear-
ing, then remove and replace with the recom-
mended 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
resistant wheel bearing grease.
C. Hub Reinstallation
1. To reinstall hub, reverse the procedures listed
above.
2. It is important to tighten the spindle nut to approxi-
mately 50 ft. lbs. (12" wrench with full hand force).
Loosen the nut then finger tighten.
3. Replace the cotter.
4. When reinstalling wheel, the following tightening
procedure is recommended by the manufacturer:
a. Place wheel lug nuts on by hand to start.
b. Tighten initially to 15 - 20 ft. lbs. (Apply 20
pounds of pressure to wrench 12" long) using
cross tightening sequence. Proceed to finish
tightening to 85 ft. lbs. (Applying 85 pounds
of pressure to wrench 12" long will yield 85 ft.
lbs. of torque).
c. Re-torque after first 50 miles of use.
