[VAC] Axles
To all.
Axles don't go bad, the rubber rods do. Basically the axles from mid 1974 on
back
are the problems.
The test is as follows.
1. Level the empty trailer.
2. Check the torsion arms. If they are parallel to the chassis, then they are
very borderline.
3. If the torsion arm goes upwards, at all, it's bad.
4. Repeat the checks with the trailer loaded.
5. Again, if the torsion arms go upwards, at all, it's bad.
6. There is a built in stop that limits the torsion arm travel. When the stop
is hit (from a bump) the trailer bottoms out, as there is no suspension left.
That's when the trouble really starts. Fatigue cracking of the shell and/or
frame as well as permanent distortion of the shell can take place, as well as
many other things.
6. Since mid 1974, the axle rubber rod failures are almost non existent,
unless the coach has been grossly overloaded for an extended period of time.
7. For complete information, please go to our web site, inlandrv.com and
click on articles. Then click on Dura-torque axles. That article explains
what the axle is, how it is made, how and why it works the way it does, and
how to check it out.
