We also provide your suspension systems as well as the axle assemblies. These components are designed to
perform a number of tasks to provide your trailer with the best and smoothest towing possible. The above drawings
offer a view of single and tandem axle assemblies in both the double eyed and slipper spring versions. Your axle
undercarriage may be equipped with double eye leaf springs or slipper leaf springs depending on the
manufacturer’s specification. Double eye leaf springs have eyes at both ends of the spring and have special
bushings to protect them from wear. They do not need lubricating. Slipper leaf springs have an eye at only one end
which is also fitted with a special bushing to protect them from wear. The trailing end of the spring is designed to
slide against the rear hangers. Either of these suspensions will provide you with comfortable trouble free towing,
but as with any mechanical parts, they should be inspected periodically depending on usage at recommended
intervals of 6 months or 5,000 miles whichever comes first. Should you find excessive wear in the hanger
components you should have them replaced by a qualified technician. Should you find excess wear, in any of the
attaching parts bolts, nuts, bushings, broken or worn out springs, you should replace them and torque attaching
bolts to the following standards as shown below.
CAUTION
Make sure the trailer is raised and supported according to the manufacturer’s requirements before beginning any
repairs of the trailer.
