2. Place a chalk mark on the center line of the front tires
approximately 10” (25.4 cm) from the floor or as
close to the hub/axle center line as possible.
NOTE
It is important the height of both marks be equally
positioned to get an accurate measurement.
3. Measure the distance between the marks and record
the measurement. Call this measurement “A”.
4. Rotate the tires 180° by moving the vehicle forward.
Position chalk marks facing rearward, even with the
hub/axle center line.
5. Again measure the distance between the marks and
record. Call this measurement “B”. Subtract
measurement “B” from measurement “A”. The
difference between measurements “A” and “B” is the
vehicle toe alignment. The recommended vehicle toe
out is specified below. This means the front of the tire
(A) is wider than the measurement at the rear (B).
MEASUREMENT
Wheel Toe-Out:
(A) - (B) = 1/8" to 3/16" (3.2 to 4.8 mm)
WHEEL TOE ADJUSTMENT
If toe alignment is incorrect, repeat steps 3-5 of “Wheel
Toe Alignment Inspection”, page 2.34, but instead
measure the distance between vehicle center and each
wheel. This will tell you which tie rod needs adjusting.
NOTE
Be sure steering wheel is straight ahead before
determining which tie rod needs adjustment.
CAUTION
During tie rod adjustment, it is very important that the
following precautions be taken when tightening tie rod
end jam nuts. If the rod end is positioned incorrectly it
will not pivot, and may break.
To adjust toe alignment:
• Hold tie rod end to keep it from rotating.
• Loosen jam nuts at both end of the tie rod.
• Shorten or lengthen the tie rod until alignment is as
required to achieve the proper toe setting as specified
in “Wheel Toe Alignment Inspection”.
IMPORTANT
When tightening the tie rod end jam nuts, the rod ends
must be held parallel to prevent rod end damage and
premature wear. Damage may not be immediately
apparent if done incorrectly.
• After alignment is complete, torque jam nuts to
specification.
