1. With both axles blocked up, remove the spring eye bolt, shackle bolt, and
equalizer bolt from the equalizer to be repaired or replaced.
2. Take the equalizer to suitable work surface and remove the worn
bushings using a suitable drift punch.
3. Drive the new bushings into place using a piloted drift punch or a close
tting bolt through the bushing.
4. Reassemble in reverse order.
CAUTION
Be sure to wear safety glasses when removing or installing force
fitted parts. Failure to comply may result in serious injury.
All of the pivot points on your standard suspension system have been tted
with anti-friction bearing materials which do not require routine lubrication.
When otherwise servicing the unit, these pivot points may be lubricated if you so
desire. If your trailer has been tted with the Heavy Duty Attaching Parts Kit, you
should lubricate periodically to ensure long component life.

Suspension
The Torex
®
suspension system is a torsion arm type suspension which is
completely self contained within the axle tube. It attaches directly to the
trailer frame using brackets which are an integral part of the axle assembly.
The Torex
®
axle provides improved suspension characteristics relative to leaf
spring axles through the unique
arrangement of a steel torsion
bar surrounded by four natural
rubber cords encased in the
main structural member of the
axle beam.
The wheel/hub spindle is
attached to a lever, called the
torsion arm, which is fastened
to the rubber encased bar. As
load is applied, the bar rotates
causing a rolling/compressive
