AIRSTREAM CLASSIC TRAILER

AXLE AND RUNNING GEAR ASSEMBLY
Each Airstream RUBBER TORSION axle is aligned during manufacturing, and double-checked on a
random basis. Alignment after delivery is the customer's responsibility.
Hitting chuck holes or rough railroad tracks while going straight will only cause misalignment after the tire
has been struck many repetitive times. Of course, a deep enough hole can affect the alignment immediately.
The worse culprit is a curb because they are normally struck at an angle. Surprisingly rear axles are
occasionally damaged when people are attempting to park beside a curb and are backing up their trailer.
As you look under your trailer is it normal for the axle to be bent up in the middle. This bend is how the
camber is obtained.
Toe-in is built into the axle by very slight bends in the axle tube on each end.
If tire wear ever indicate misalignment check with your dealer for the nearest location having the proper
equipment.
CAUTION
: Never allow heat to he applied to the axle tube since the rubber providing the spring
torsion action will be severely damaged.
