20-4. STEERING ALIGNMENT (Cont'd)
b. Caster and Camber Adjustment
NOTE
Caster and camber adjustments are basically the same for all four
wheels. This procedure covers the right front wheel.
1.
Remove wheel (TM 9-2320-280-20).
2.
Remove two nuts (7), washers (2), capscrews (1), and washers (2) from upper control arm (8) and
mounting brackets (3).
3.
Loosen two capscrews (6) and four nuts (5) on two mounting brackets (3) and airlift bracket (4).
NOTE
Shims are available in 0.06-in. (1.52 mm) and 0.12-in. (3.05 mm)
thicknesses.
4.
Add or subtract shim(s) (9) as required to bring caster and/or camber withing specifications
(table 20-1 or
20-2). Suspension alignment change in
relation to
shim selection is
shown in
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.
