nev-R-Lube Bearing inspection
1 Jack trailer at marked JacK location pad behind
axle on main frame.
2 Check for excessive wheel end-clearance by
pulling the tire assembly toward you and by
pushing the assembly away from you. Slight end-
play is acceptable (0.001 to 0.010 in.).
3 Rotate tire slowly forward and backward. The
wheel assembly should turn freely and smoothly.
4 Excessive wheel end-play, restriction to rotation,
noise, or bumpy rotation should be remedied by
replacing the bearing unit
5 Bearing units should be inspected every year or
12,000 mi., whichever comes first.
A slight amount of grease-weeping from the seal area
is normal. Excessive leakage may indicate abnormal
bearing operation. Bearing end-play inspection,
drum removal/installation, and bearing replacement
procedures are described in the Dexter Operation
Maintenance Manual enclosed in your owner’s packet.
Airstream recommends that these procedures are
performed by a qualified Dexter service technician, due
the need of specialized tools and training.
narrow Body trailer Bearing inspection and
maintenance
Narrow body trailers, under 25 ft, should be maintained
as follows:
1 Jack trailer at marked JacK location pad behind
axle on mainframe. See illustration in paragraph
tire Changing on page 8-7
2 Remove hubcap or spindle cover, wheel, and tire.
3 Remove cotter pin.
4 Remove dust cap.
5 Remove spindle nut and washer.
6 Remove bearings, hub and rotor.
7 Lay down hub and rotor with inside grease seal
down. Knock out inner bearing and grease seal
using wood or plastic dowel and hammer.
8 Clean all parts thoroughly with kerosene.
9 Check all bearings and races for chips or
roughness of any kind. Any damaged component
must be replaced.
10 Pack bearing with a good grease (No. 2 grade-265
ASTM penetration or equivalent).
11 Install inner bearing.
12 Install new grease seal in hub or rotor using
wooden or rawhide mallet.
13 Install hub and drum on spindle.
14 Install outer bearing.
15 Install washer and spindle nut.
16 While rotating the wheel, tighten the spindle nut
with an adjustable wrench until there is a slight
tension. Then back off one notch and install cotter
pin. There should now be from 0.001 to 0.010 in.
end play in hub if not, back off one notch
17 Check the lug nuts at 10 and 25 miles, and
recheck at 50 miles of travel.
See Specifications Chart in Section 4 - Floor Plans and
Specifications for wheel torque ratings.
When greasing bearings by hand, place a glob of
grease in the palm of one hand and push the large end
of the bearing down into the grease. Keep turning the
bearing around and forcing it down through the grease
until the grease is extruded up through the opposite
end. Wipe the extra grease in your hand around the
outside of the bearing. It is not necessary to fill the hub
and dust cap with grease.
Brakes
Due to normal brake lining wear, the brakes and the
controller setting should be checked and readjusted
every six months or 10,000 miles, whichever comes
first.

Replacing Power Head
It is essential that the following procedure be used
before the power head is replaced on the post:
1 With 12-volts connected, ground the power
head to trailer A-frame. Operate main switch in
post-retracting direction until the motor stops
automatically.
2 Using emergency handle, crank post clockwise by
hand until fully retracted, then turn crank one turn
counterclockwise.
3 Replace head on post and make sure that drive pin
is engaged with post coupler. Tighten Allen set-
screws.
