Removal (Fig. 45)
1. Park vehicle on a level surface, raise and support ve-
hicle cargo bed (if installed), shut engine off and engage
the parking brake. Remove key from the ignition switch.
2. If rear differential is to be disassembled, drain lubri-
cant from rear differential.
3. Jack up and support rear of vehicle (see Jacking Ve-
hicle in the Safety Instructions section of Chapter 1 −
Safety). Once the machine is raised, support rear of en-
gine/transmission mount to prevent it from moving or
shifting during rear differential removal.
4. Remove parking brake caliper, driveshaft and park-
ing brake rotor from rear differential (see Parking Brake
Caliper in the Service and Repairs section of Chapter 5
− Chassis). Position and support disconnected rear
driveshaft away from rear differential.
5. Disconnect wire harness connector from rear differ-
ential lock solenoid on right side of differential.
6. Remove rear wheel assembly, brake caliper and
brake rotor from both sides of machine (see Brake Sys-
tem in the Service and Repairs section of Chapter 5 −
Chassis).
7. Remove both CV axle assemblies from machine:
A. Using wheel hub hole to access flange head
screws, remove screws that secure wheel hub as-
sembly to rear axle (Fig. 46). It is not necessary to re-
move wheel hub assembly from CV axle so spindle
nut does not have to be loosened.
IMPORTANT: Make sure to not damage the oil
seal on the rear differential with the pry bars
when removing the CV axle assemblies.
B. Use two small pry bars (180
o
apart) to carefully
leverage the CV axle out of the differential. Use even
pressure on both pry bars (Fig. 47).
C. Carefully pull wheel hub assembly with attached
CV axle through opening in rear axle and remove
from vehicle.
D. Repeat procedure for second CV axle assembly.
IMPORTANT: Before loosening fasteners that se-
cure rear differential, support differential to prevent
it from falling during removal.
8. Remove fasteners that secure the LH and RH rear
mounts to machine frame and rear differential. Remove
rear mounts. For assembly purposes, note that solenoid
controller assembly (item 22) is secured to the machine
frame with fasteners for the RH rear mount.
9. On the front of the rear differential, remove two (2)
flange head screws that secure the differential to the en-
gine/transmission mount.
10.On the sides of the rear differential, remove flange
head screws that secure the differential to the engine/
transmission mount.
IMPORTANT: Weight of rear differential is approxi-
mately 46 pounds (21 kg). Take care when removing
the differential from machine.
11.Carefully lower rear differential from machine and re-
move toward the rear of the machine.
