Tighten hose clamps as necessary.
IMPORTANT: Do not overtighten hose
clamps, as hose life can be adversely af-
fected.
3.5
Ensure hose support brackets are se-
curely fastened. Make sure hoses are not
located near sources of wear, abrasion, or
high heat.
IMPORTANT: When replacing hoses, install
service-type knitted or braided yarn-reinforced
neoprene hose. Extended-service-life silicone
hoses may also be used. See the Alliance Parts
Catalog at

4.
Check the steering wheel for excessive play.
4.1
Start the engine. With the front tires
straight ahead, turn the steering wheel
until motion is observed at the front
wheels.
4.2
Align a reference mark on the steering
wheel to a rule, then slowly turn the steer-
ing wheel in the opposite direction until
motion is again detected at the wheels.
4.3
Measure the lash (free play) at the rim of
the steering wheel. Excessive lash exists
if steering wheel movement exceeds 2-1/2
inches (64 mm) with a 20-inch (508-mm)
steering wheel, or 2-1/4 inches (57 mm)
with an 18-inch (450-mm) steering wheel.
4.4
If there is excessive lash, check the steer-
ing system for wear or incorrect adjust-
ment before operating the vehicle.
