B. Bearing/Seal Inspection and Replace ment
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 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 corro sion
and wear. If any rust or wear exists on the bear-
ing, then remove and replace with the manufac-
turer's recommended part.
3. If the bearings are in good condition, repack ing
the grease should be done at this time. Hand
pack each bearing individually using a premium
water-resistant wheel bearing grease.

SUPPLEMENTAL TRAILER INFORMATION
A. Information Contained on Sidewall of the Tire
Both U.S. and Canada Federal regulations require
tire manufacturers to place standardized information
on the sidewall of all tires. This information identi-
fies and describes the characteristics of the tire. See
Figure S21.
Figure S21: Axle Components
Maximum Permissible Inflation Pressure: Indicates
the tire manufacturer's maximum permissible pres-
sure and/or the pressure at which the maximum load
can be carried by the tire. Refer to the Certification
Label on the port forward half of the trailer for the
correct tire pressure for your trailer.
U.S. DOT Tire Identification Number (TIN): This
begins with the letters 'DOT' and indicates the tire
meets all federal standards. The next two numbers
or letters are the plant code designating where it was
manufactured, the next two are the tire size code,
and the last four numbers represent the week and
year the tire was built. For example, the numbers
5110 mean the tire was built the 51st week of 2010.
The numbers are identification codes used for trace-
ability. This information is used to contact customers
if a tire defect requires a recall.
