Installing the Steer Axle Sensor
Bracket
Preparing the Steer Axle Sensor Brackets
1. Locate and mark the center of the steer axle.
2. Using chalk or a permanent marker, mark the top of the steer

this area. If the axle is heavily caked with dirt or grease, use
Brakleen to remove the worst.
3. Using 40-grit medium sandpaper or a pneumatic grinder,
sand the 6” area until nothing remains but bare metal. We
recommend that you partially sand down the mold line as
well.

and that no axle paint is left under the pad. If there is any
paint at all that will be touching the brackets, sand until it has
been removed.

Welding the Bracket
NOTE: Air-Weigh takes no responsibility for damage or failure of
the steer axle due to improper welding.
1. Place the new bracket assembly at the center of the axle.
Use C clamps to hold the bracket in place. Make sure you
leave the alignment tool in the bracket assembly while
welding.

Adding a Protective Spray Paint Coating
To prevent steer axle corrosion, we recommend you spray paint
around the base of the bracket.
1. Using any enamel-based spray paint, paint around the base
of the bracket and over the welded section. Paint all bare
metal around the bracket completely.
2. Once the paint is dry, we recommend that you paint all
exposed metal a second time.
