Disassembly (Fig. 6)
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from ignition
switch.
CAUTION
When changing attachments, tires or perform-
ing other service, use correct supports, hoists
and jacks. Make sure machine is parked on a
solid, level surface such as a concrete floor.
Prior to raising machine, remove any attach-
ments that may interfere with the safe and prop-
er raising of the machine. Always chock or
block wheels. Use jack stands or other ap-
propriate load holding devices to support the
raised machine. If the machine is not properly
supported, the machine may move or fall, which
may result in personal injury.
2. Jack front of machine off ground (see Jacking In-
structions in Chapter 1 − Safety). Support machine to al-
low front suspension to hang freely from machine.
3. Remove front wheels (see Front Wheels and Hubs).
4. Support axle to prevent it from shifting or falling.
5. To remove leaf springs:
A. Loosen fasteners that secure springs to frame at-
tachment points.
B. Loosen and remove cap screws and lock nuts
that secure spring plate (item 17).
C. Remove shackles, bushings, shoulder bolts, lock
washers and hex nuts from spring and frame.
D. Remove leaf springs from machine.
IMPORTANT: If leaf spring replacement is needed,
always replace both springs for proper vehicle per-
formance.
6. If front axle removal is required, remove steering cyl-
inder (see Steering Cylinder Removal in the Service and
Repair Section of Chapter 4 − Hydraulic System) and
shock absorbers from axle.
Assembly (Fig. 6)
1. If axle was removed from vehicle, position and sup-
port axle under frame.

2. To install leaf springs:
NOTE: When installing leaf springs, make sure front
axle and spring plate are centered on the screw head
and nut that attach spring leaves.
A. Loosely attach springs to frame with shackles,
bushings, shoulder bolts, lock washers and hex nuts.
Do not fully tighten fasteners.
B. Install spring plate (item 17) to top of spring as-
sembly with curved edge toward spring.
C. Install and tighten cap screws (item 16), hard-
ened washers (item 19) and lock nuts (item 20) in a
crossing pattern until spring plate, leaf spring and
axle are in contact.
D. Fully tighten fasteners that secure springs to
frame.
E. Using a crossing pattern, torque lock nuts (item
20) that secure spring plate 34 ft−lb (46 N−m). Again
using a crossing pattern, torque lock nuts from 69 to
85 ft−lb (94 to 115 N−m). Finally, use a crossing pat-
tern to check that lock nuts are all torqued from 69 to
85 ft−lb (94 to 115 N−m).
3. If shock absorbers were removed, install shocks to
vehicle. Make sure that spacer is positioned between
shock and frame attachment point during shock installa-
tion.
4. If steering cylinder was removed, install steering cyl-
inder (see Steering Cylinder Installation in the Service
and Repair Section of Chapter 4 − Hydraulic System)
Failure to maintain proper lug nut torque could
result in failure or loss of wheel and may result in
personal injury.
5. Install wheel with valve stem facing out and secure
with lug nuts. Torque lug nuts evenly in a crossing pat-
tern from 55 to 75 ft−lb (75 to 102 N−m).
6. Lower vehicle to ground.
7. Check front suspension and steering operation.
Make sure that components do not contact hoses and/or
wires.
