General Troubleshooting
Check the following before you begin:
o Has the suspension been modified in a way that would affect steering?
. Are tire sizes and air pressure correct?
. lsthe steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adiusted?
. ls steering fluid reservoirtilled to proper level?
. ls the engine idle speed correct and steadyT

NOTE: For proper inspection/adjustment of the wheel
alignment check and adjust the following before check-
ing the alignment.
. Check that the susoension is not modified.
. Check the tire size and tire pressure.
. Check the runout of the wheels and tires.
. Check the suspension ball joints. (Hold a wheel with
your hands and move it up and down and right and
left to check tor wobbling.)
Inspection
NOTE: Use commercially-available computerized four
wheel alignment equipment to measure wheel align-
ment {caster, camber, toe, and turning angle). Follow
the equipment manufacturer's instructions.
1. Check the caster angle.

make sure thev are still oarallel.
ADJUSTING BOLT
With a wrench, tighten the pressure bolt until the
ball ioint shaft pops loose from the steering arm.
@ wear eye protection. The ball ioint
can break loose suddenly and scrtter dirt or other
debris in your eyes.
Remove the tool, then remove the nut from the end
