Uncoupling the Fifth Wheel Trailer
Follow these steps to uncouple your fifth wheel hitch
trailer from your tow vehicle.
• Blocktrailertirestopreventthetrailerfrom
rolling before jacking the trailer up.
• Disconnecttheelectricalconnector.
• Disconnectthebreakawaybrakeswitchlanyard.
• Ifthetowvehiclehasatailgate,lowerit.
• Makecertainthatgroundsurfacebelowjack
base will support trailer tongue load.
• Pullthedroplegpinsandreleasethelegstothe
ground.
• Positiondroplegtothedesiredlocationand
re-install pins.
CAUTION
If the drop legs are not set at the same level,
one of the drop leg jacks can be overloaded
and can be damaged.
• Extendthejackandtransfertheweightofthe
trailer tongue to the jack.
• Continuetoextendthejack(s),makingsurethat
the ground is providing stable and level support
for the trailer.
• DoNOTdrivethetowvehicleyet!
• Openthefifthwheellocksbypullingonthe
release handle
• Slowlydrivethetowvehicleawayfromthe
trailer.
• Raisethetowvehicletailgate.
AXLES
Your trailer is equipped with a rubber torsion arm
suspension system which is completely self-
contained within the axle tube and is equipped with
Safe-T-Lube wheel bearing lubrication system. The
axles attach directly to the trailer frame using
brackets which are an integral part of the axle as-
sembly. The torsion axles provides improved sus-
pension characteristics relative to leaf spring axles
through unique arrangement of a steel torsion bar
surrounded by natural rubber cords encased in the
main structural member of the axle beam.
The wheel/hub spindle is attached to a lever, called
the torsion arm, which is fastened to the rubber en-
cased bar. As load is applied, the bar rotates causing
a compression resistance. This action provides the
same functions as conventional sprung axles with
several operating advantages including independent
suspension.
Except for periodic inspection of the fasteners used
to attach the torsion axle to the trailer frame, no other
suspension maintenance is required on the axles.
They are, of course, subject to the maintenance and
inspection procedures regarding brakes, hubs, bear-
ings, seals, wheels and tires.
The Safe-T-Lube wheel bearing lubrication system
allows for periodic lubrication of the wheel bearings
without removing the hubs from the axles. This fea-
ture consists of axle spindles that have been specially
drilled and assembled with grease fittings in the ends.
When grease is pumped into the fitting, it is chan-
neled to the inner bearing and then flows back to the
outer bearing and evidentially back out the grease
cap hole. Bearings should be lubricated every 12
months or 12,000 miles.
To lubricate the hubs, the procedure is as follows:
1. Remove the rubber plug from the end of the
grease cap.
2. Place a grease gun onto the grease fitting located
in the end of the spindle. Make sure the grease
gun nozzle is fully engaged on the fitting.
3. Pump grease into the fitting. The old displaced
grease will begin to flow out the cap around the
grease gun nozzle.
4. When the new clean grease is observed, remove
the grease gun, wipe off any excess, and replace
the rubber plug in the cap.
5. Rotate hub or drum while adding grease.
