Adjusting the Front Wheel
Toe-in
No Parts Required
Procedure
The toe-in should be 1/8-5/8 inch (3-16 mm) with the
following parameters:
• The tire pressure should be at 12 psi (83 kPa).
• The ride height should be correct before setting the
toe-in; refer to the Adjusting the Front Suspension
procedure in Maintenance , page 26.
• The vehicle should be driven back and forth a few
times to relax the A-arms.
• Measure the toe-in with the wheels facing straight
ahead and a 175-225 lb (79-102 kg) operator in the
driver's seat.
Note: The driver should drive up to the
measurement area and stay seated in the vehicle
while the measurement is being taken.
If the vehicle will be run with medium to heavy loads
most of the time, set the toe-in on the high side of
the recommended amount. If it is going to be run
with a light load most of the time, set the toe-in on
the low side of the recommended amount.
1. Measure the distance between both of the front tires
at the axle height at both the front and rear of the
front tires (Figure 11). A fixture or alignment gauge
is needed for the rear measurement of the front tires
at axle height. Use the same fixture or alignment
gauge to accurately measure the front of the front
tires at axle height (Figure 11).
1. Tire center line-back
2. Tire center line-front
3. Axle center line
2. If the measurement does not fall within the specified
range (refer to the dimensions and parameters at the
beginning of this procedure), loosen the jam nuts at
both ends of the tie rods (Figure 45).
