Power Jack; Power Jack; Spare Tire Carrier; Tire Rotation - Airstream Classic 2020 Owner's Manual

Spare Tire Carrier

The spare tire for Airstreams are stored under the front
of the trailer. The front handle of the tire carrier is a 1
in. tube protruding out from under the front A-frame
on the curbside. It is secured by a bracket and bolt
along the inside of the A-frame rail. Removing the bolts
allows the front of the tire carrier to be lowered and the
spare tire to be removed.
The spare tire carrier is designed to carry an
undamaged tire and rim assembly of the type and
size specified for the trailer. Never place a severely
damaged wheel assembly with a damaged partial
tire, or a rim only, in the carrier.

Nev-R-Lube Drums/Bearings

Classic trailers are equipped with Nev-R-Lube
bearings. Dexter's Nev-R-Lube bearings are comprised
of opposed tapered roller bearing cones sealed
inside of a precision ground, one-piece double cup
arrangement. These bearings are designed with
a small amount of axial end-play. The end-play is
essential to the longevity of the bearings service life.

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.

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.
