• Measure the ride height on a flat surface, from the
bottom of the front tongue to the ground.
1. Jack the front end of the vehicle off of the ground; refer
to Jacking the Vehicle, page 20.
2. Remove the travel limiting bolt (Fig. 25).
3. Loosen the centering bolts in the front A-arm (Fig. 25).
4. Remove the ride height adjustment bolt (Fig. 25).

5. Rotate the front A-arm to the desired position (refer to
the note below) and replace the ride height adjustment
bolt (Fig. 25).
Note: The A-arms are made with rubber and have different
spring rates. Because of the different spring rates, the
A-arms come adjusted from the factory based on that
spring rate. Generally the adjustment bolts will be installed
in hole number 2, 3, or 4 (Fig. 26) and it may be different
from the left side (driver side) to the right side (passenger
side). If the A-arms look like they are sagging, then they
should be adjusted to the next higher number (Fig. 26).
Each hole equals about 3/4 in. (19 mm) of adjustment at the
wheel. You will also need to do this if you are adding heavy
attachments or carrying heavy loads often.

6. Torque the ride height adjustment bolt to 135–165 ft.-lb.
(183–224 N⋅m).
7. Replace the travel limiting bolt (Fig. 25).
Note: The vehicle may need to be lowered to the ground on
that side to install the bolt.
8. Tighten and torque the centering bolts to
240–290 ft.-lbs. (325–393 N⋅m).
9. Check the ride height at the front tongue per the
dimensions and parameters given at the beginning of
this procedure.
Adjusting Front Wheel Toe-In
Check the front wheel toe-in after every 100 operating
hours, or annually, whichever occurs first.
The toe-in should be 1/8–5/8 in. (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 Adjusting the Front Suspension, page 24.
• 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.
