FRONT AND MIDDLE AXLE REPLACEMENT (Continued).
Using a hydraulic bottle jack (2), raise by approximately three in. (7.62 cm) the end of the
tandem beam supporting the axle to be removed.
Place a jack stand (1) under the tandem beam and lower the beam to rest on the jack
stand. Repeat Step (1) for the tandem beam on the opposite side, but leave the jack in
position as a secondary support.
Always use jack stands to support the trailer when removing a tire and wheel
assembly. Serious injury can result if the jack fails and the axle is not supported.
Using a handle and wrench, remove ten lug nuts securing each wheel and remove the inner
and outer wheels on both sides of the axle to be removed.
Position a dolly jack under balance point of front axle and raise dolly until dolly comes in
contact with axle.
