Note: Lifting the trailer with air system pressurized will overextend the air
bags and can result in damage to the air bags.
CAUTION
Do not lift or support the trailer on any part of the axle or suspension
system. Never go under any trailer unless it is properly supported on
jack stands which have been rated for the load. Improperly supported
vehicles can fall unexpectedly and cause serious injury or death.
2. Measure from king pin to spindle center on each side. To simplify this
process, plumb lines may be dropped from the king pin and from the
center line of each spindle end. Measurements “A” and “B” can then be
taped on the oor to eliminate any miss measurement due to sagging of
the tape for long measurements. Compare A and B measurements (see
Figure 1).
3. Suspension front pivot connection is torqued to 270 Ft. Lbs. when the
suspension is shipped. The axle should be aligned on the trailer in this
condition.
