JJRIOR TO PERFORMI~THESE
TESTS,
Visually inspect steering components:
1. Check all four tires and rims for wear, inflation, damage, or warping.
a. Adjust tire pressure (TM Q-2320-387-10).
b. Replace any
unserviceable
rims (para. 8-4).
2. Check steering linkage for damage.

test will usually reveal problems with frozen brake calipers.
If the wheels are out of alignment or if the tires are worn unevenly,
