A. Lash Area
Fig. 15.16, Measuring Lash at the Steering Wheel
3.3 Measure the lash (free play) at the rim of
the steering wheel. Excessive lash exists
if steering wheel movement exceeds 2-1/4
inches (57 mm) with an 18-inch (450-mm)
steering wheel.
See local/federal regulations for accept-
able ranges of lash.
4. Check the brake lining wear on all vehicles, in-
cluding those with automatic slack adjusters.
Proper brake operation is dependent on periodic
maintenance and inspection of the brake linings.
4.1 Check that brake linings are free of oil and
grease.
4.2
Inspect the thickness of the brake linings.
If the axle assembly is equipped with a
dust shield or backing plate, remove the
inspection plugs. If any brake linings are
worn to less than approximately 1/4 inch
(6.4 mm) at the thinnest point, have the
linings replaced on all brake assemblies
on that axle. See Group 42 of the S2
Chassis Workshop Manual for lining re-
placement instructions and camshaft end-
play inspection.
4.3
Check the brake drums for wear and
cracks.

shields or backing plates, if so equipped,
are installed.
