Sulfonate grease if possible. It is available under Part No.
2500038 and is packaged in 14 oz. tubes. You can pur-
chase this grease from any ShoreLand’r
®
dealer or else
contact ShoreLand’r

direct. (1-800-859-3028)
Pack the bearings by forcing the grease into all the small
cavities in the bearings. Fill the cavity in the hub with grease.
Fill the dust cap half full with grease when greasing the hubs.
Make sure the grease seals are in good, usable condition
and do not show signs of them allowing grease to seep
around the spindle. Most likely the seals will receive dam-
age when removed and should be replaced with new seals.
Keep the bearings and grease free of any dirt or foreign
matter.
The wheel bearings should be packed anytime during the
year should you plan on storing the trailer for a period of
time.
Be sure the bearings are adjusted properly according to
the bearings adjustments mentioned under Bearing adjust-
ment. Too tight of bearing adjustment will cause the bear-
ings to heat up faster than one that is properly adjusted.

GREASE SEALS
Inspect the grease seals periodically. A visual inspection is suffi-
cient and is done quite easily on a trailer without brakes. It is normal
to see a small oil film around the seal area. This should not hurt
anything. However, if the leakage becomes excessive it is time to
replace the seal before too much grease escapes causing bearing
failure. It will also cause the brakes to grab on a brake equipped
trailer. Replacement of the seal requires removing the complete
hub assembly from the spindle. Trailers equipped with disc brakes
will have to have the brake calipers removed so the rotors can be
removed from the spindle.
On axles with brake drums you must remove the complete brake
drum assembly to inspect the seals. It is very important that you
check the seals on brake axles periodically to make sure they are
not leaking. Leaking seals allows the grease to get on the brake lin-
ings thus causing grabby brakes. Eventually the brake linings will
become saturated with grease and will have to be replaced.

Grease Seal and Bearing Protectors
If you decide to add bearing protectors to an older model trailer or
one that is not equipped with bearing protectors, we suggest you
install the Spindle Seal Kit available through your dealers. It offers
stainless steel sleeves and spring loaded seals for your axle. This
will prevent rust from chewing up the seals allowing grease to leak
out.
RECOMMENDED LUBRICANT
Over-based calcium sulfonate grease is installed at the factory
because it is a very compatible grease that will blend well with most
other greases. We recommend that you continue to add grease
to the hubs when grease is needed. ShoreLand’r
®
has this grease
available in a 14 oz. tube to fit a standard size grease gun. The
part number is 2500038 and can be obtained from any authorized
ShoreLand’r
®
dealer. However, any good marine grade water re-
sistant grease that is compatible to over- based calcium sulfo-
nate is recommended.
BEARING REPACKING
Check the grease in your hubs once a year. In most instances, if
a good quality lubricant is used and the lubricant levels are main-
tained, it may not be necessary to repack the bearing. However,
should the grease appear to be contaminated or broken down, re-
move all of the old grease from the bearings and hubs and com-
pletely repack. Removing the rear bearing will most likely cause
damage to the rear seal. A new one should be installed when reas-
sembling.
BEARING ADJUSTMENT
The wheel bearings have been adjusted at the factory. To maxi-
mize bearing life, however, we suggest that you check the bearing
adjustment after the first 50 miles of use, then every time the bear-
ings are repacked. Contact an authorized ShoreLand’r
®
dealer
for service.
Bearing adjustment can be checked by jacking up one side of the
trailer. Grip the edge of the wheel and see if you can rock it or move
it. If you have movement remove the dust cap or bearing protector,
and the cotter key. While rotating the wheel, tighten the spindle nut
to a recommended 20 inch-pounds of torque if your trailer has 1-
1/16” – 1-1/16” bearings or 30 inch-pounds of torque if your trailer
has 1-3/8” – 1-1/16” bearings. Do not over tighten. NOTE: The
spindles have cross holes drilled at 90 degree intervals for the re-
taining cotter key. Look for the hole in the spindle through the slots
in the spindle nut. If you can see any part of the hole through the
