34-3.   SUSPENSION ALIGNMENT INSTRUCTIONS (Cont'd) NOTE Caster and camber adjustments are basically the same for all four wheels. This procedure covers the right front wheel. 1. Remove wheel (para. 8-3). 2. Remove two locknuts (7), washers (2), capscrews (1), and washers (2) from upper control arm (8) and mounting brackets (3). Discard locknuts (7). 3. Loosen two capscrews (6) and four nuts (5) on two mounting brackets (3) and airlift brackets (4). NOTE •  When adjusting front and rear suspension camber, add or subtract shims as matched sets under both upper control arm mounting brackets. •  Shims are available in 0.060-in. (1.52-mm) and 0.120-in. (3.05-mm) thicknesses. 4. Add or subtract shim(s) (9) as required to bring caster and/or camber within specifications (table 34-1). Suspension alignment change in relation to shim selection is shown in table 34-2. b.  Caster and Camber Adjustment NOTE • Subtracting shims will affect caster/camber in the opposite direction as compared to adding shims. • For 0.06 in. (1.52 mm) shims, reduce the values in the table by half. • For larger changes, combinations of additions or subtractions will provide desired results.
