Trailer jacks are special jacks that mount off the end of trailers. The trailer jack is operated by using a cranking handle. When the handle is cranked, the end of the trailer rises until your trailer hitch is equal in height to the ball hitch on your truck or SUV. If you ever need to store your trailer jack away in tight quarters, it might be necessary for you to know how to disassemble it.

Step 1

Clear your trailer of any towed vehicles such as a boat or lawn tractor. Unhook your trailer if it is attached to the back of a truck or SUV.

Step 2

Unbolt the bolts that hold your jack to the trailer. You may have to use a spray lubricant if the nuts are tight. Once the bolts are loosened pull the jack away from the trailer.

Step 3

Lay your jack flat on a work bench and finish removing the mounting bar assembly. There are four bolts on the back of the mounting bar plate. The bolts will have to be removed with an open-ended wrench because the space between the bolts is not large enough for you to fit both a ratchet and socket head.

Step 4

Loosen the bolt on the end of the handle crank. This bolt holds the handle crank in place on your trailer jack.

Step 5

Remove the bolt that holds the caster wheel in place on your jack. This bolt can be removed also be removed with a wrench.
