Shimming requires exhausting of the air ride system to open
shim points!
Trailer may be adjusted using manual raising and lowering valve
or +3/-3 height control.
Air pressure gauges may be located on suspension air bag for
developing air pressure for axle load charts.
Shimming objective is to have all rear section bottom beam flanges level (top
of axle to bottom flange of rear beam should be 6 1/2" at standard ride height).
A chart should be kept of all the loads that require shimming and must be
developed through trial and error.
