How do I install a dual-axis adjustable camber/caster bushing?

Take an initial alignment reading, remove the tire/wheel and the existing upper ball joint bushing, then install the dual-axis bushing in the Neutral (0 degree) position by dialing the "N" of the inner bushing to the slot of the outer bushing. Take a new alignment reading, use the chart to find upper/lower letter codes, index the bushings accordingly, torque the castle nut to spec, install the cotter pin, and re-align and road test.

What do the upper and lower letters on the adjustment chart mean?

The UPPER letter is the code for positioning the INNER adjuster, and the LOWER letter is the reference for positioning the OUTER adjuster. If a chart box has two upper or two lower letters, position the bushing between the two letters.

Do I need to remove the dual-axis bushing to change its adjustment?

No. The instructions state it is not necessary to remove the dual-axis bushing to index it to the proper position; simply rotate the inner and outer bushings to the chart positions.

What tools make adjusting the bushing easier?

The instructions note that using a thin wall socket or channel-type pliers will make adjustments easy.

Does the bushing kit include a new castle nut?

Yes. A new castle nut is included with the bushing and should be installed to allow proper cotter pin installation; torque it to manufacturer's specifications.

This document is a one-page set of installation instructions for Ford/Dodge Dual-Axis Adjustable Bushings, used to adjust camber and caster at the upper ball joint. The 11-step procedure explains: taking an initial alignment reading to confirm the vehicle is out of OEM specification; removing the tire/wheel and the existing upper ball joint bushing; installing the dual-axis bushing in the Neutral (0 degree) position by aligning the "N" of the inner bushing with the slot of the outer bushing (Illustration #1); taking a new alignment reading; consulting the vehicle-specific chart where the intersection of required camber and caster changes yields upper and lower letter codes (Illustration #2); and indexing the inner bushing's upper letter to the outer bushing slot while dialing the outer bushing's slot to the knuckle location per the lower letter (Illustration #3). It notes the bushing need not be removed to re-index, that a thin wall socket or channel-type pliers ease adjustment, and that a new castle nut is included for proper cotter pin installation. Final steps cover torquing the castle nut to manufacturer's specifications, installing the cotter pin, and performing a final alignment and road test. The form is identified as FORM# FXR 042010.
