How to Adjust a Trailer Equalizer Hitch
- 1). Load your tow vehicle with all the items you will be taking on your trip and park it on a flat, level surface. Use a measuring tape and measure each corner of the vehicle at a convenient reference point (such the bottom of the bumper) to the ground. Make a note of these measurements.
- 2). Connect the load distributing bars to your hitch and measure the height of your vehicle again as in Step 1. Be aware that ideally your vehicle should drop at all four corners equally if your hitch is set up properly. Follow subsequent steps if it did not.
- 3). Add spacer washers (to a maximum of eight) to the hitch head if your hitch is under-adjusted, or if the rear of the vehicle dropped more than the front of the vehicle when the load distributing bars were installed. Add spacers by loosening the hitch head bolts with an adjustable wrench in a counterclockwise direction. Tilt the hitch head forward to add spacers. Re-tighten the hitch head bolts in a clockwise direction with an adjustable wrench.
- 4). Remove spacer washers if your hitch is over-adjusted, or the front of your vehicle dropped more that the rear of the vehicle when the distributing bars were installed. Loosen the hitch head bolts with an adjustable wrench and remove one or more washers (there must be a minimum of four spacers left on the hitch head). Re-tighten the hitch head bolts with an adjustable wrench in a clockwise direction.
- 5). Fine tune your adjustments by removing or adding spacers in the above fashion until the vehicle drops evenly at all four corners. Tighten all hitch bolts when complete.
