AXLE AND RUNNING GEAR

Each RUBBER TORSION axle is aligned during manufacturing, and double-checked
on a random basis. Alignment after delivery is the customer's responsibility.
CAUTION
: Never allow heat to he applied to the axle tube since the rubber
providing the spring torsion action will he severely damaged.

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.
