INSPECT BALL JOINTS
Note: A set of ball joints and/or rod ends will wear
at the same rate. If a ball joint and or rod end
is worn out, then all should be replaced as
a set.
1: Tie off the front wheels so that they cannot turn.
2: While watching the ball joints, rapidly rotate the
steering wheel to the left and right.
3: If the housing moves up or down on the shaft
then the ball joint is worn out and should be
replaced. Refer to section Replacing a Ball Joint
for information regarding replacing ball joints.
4: Untie the front wheels.
5: Reconnect the main positive and negative cables
at the batteries.
6: Remove the blocks from behind the wheels.
7: Release the parking brake and test drive.

necessary to remove the steering gear to
perform this procedure. Refer to Replace
