Fig 9: To unseat the bolts once they have been torqued, use the sledge hammer and strike the nut (still attached to the bolt)
which will drive the head of the bolt loose.
Fig 10: Remove the rubber caps on the brake wiring and save them for re-use on the DS of the trailer.
Cut the brake wires just behind the copper crimp connectors.
The front axle is now free and can be lowered to the ground.

Place the floor jack under the rear axle to support it.
Repeat steps 3 and 4 for the bolts holding the springs on the rear axle.
(4 bolts on equalizers (both sides) and 2 bolts on the rear spring hanger brackets) DISCARD OLD HARDWARE
Remove the rubber caps on the wiring and save them for re-use.
Cut the wiring on the rear axle just behind the copper crimp connectors (Fig. 10)
The rear axle should now be free and can be lowered to the ground.

10 Place the floor jack under the reversed front axle and raise it into position. Wiring will now be on the Off Door Side of the trailer.
Fig 14: Insert NEW bolts through the yellow octagon plates and thru the end of the spring.
The longer side of the octagon plate should be facing up as shown in the photo.
Drive the Bolt heads in place with a sledge hammer in all locations.
Fig 15: When putting the NEW nuts back on the bolts, tighten until at least 2 threads protrude from the face of the nut.

FIG 17

11 Fig 16: When re-installing NEW bolts on the equalizer, make sure the shackle brackets are angled upwards as shown.
This is how the equalizer should look after bolts have been installed.
Tighten the 6 bolts for the front axle springs with the impact, socket and wrench.
Fig 17: At the front axle you will have 2 blue wires and 2 white wires.
The 2nd pair of Blue & White wires is from the jumper that was removed from the Door Side and brought over to the Off Door side.
Strip the wires back 3/8" to 1/2", then insert the following wires into a copper crimp connector:
Two WHITE wires and one BLACK wire from the wheel hub.
Two BLUE wires and one BLACK wire from the wheel hub.
Crimp the connectors on the wires, and then put a rubber boot over the connection.
Secure the wires to the axle with a wire tie to keep them out of harms way.
12 Use the floor jack and raise the reversed rear axle in place.
Insert NEW bolts through the yellow octagon plates and thru the end of the spring.
The longer side of the octagon plate should be facing up.
Drive the Bolt heads in all locations, in place with the sledge hammer.
When putting the NEW nuts back on the bolts, tighten until at least 2 threads protrude from the face of the nut.
