The steering wheel is critical to vehicle safety. If an

inspection reveals any problem, contact an autho-

rized Sterling service facility to solve the problem

before operating the vehicle. Conduct these checks

on a level surface with good visibility to all sides.

1 Steering wheel free play

1. Set the parking brake and chock the rear tires.

2. On vehicles with a manual transmission, make

sure that the shift lever is in neutral. 

On vehicles with an automatic transmission,

make sure that the shift selector is in “P” (park).

3. Start the engine.

4. Starting with the steering wheel in the straight-

ahead (neutral) position, turn the steering wheel

clockwise to the point where resistance is first

felt. Then do the same thing in the counterclock-

wise direction.

5. Measure the amount of steering wheel move-

ment between these two points. This is the

steering wheel free play. If the free play is not

within these limits, contact an authorized Ster-

ling service facility.

NOTE:

Before doing this check, make sure that the adjust-

ing lever is in the locked position.

1. Move the steering wheel back and forth on the

steering column, first in an up and down direc-

tion, and after that to the right and left.

2. If any problem is found, contact an authorized

Sterling service facility.
