7. Pull the rear gearcase towards the rear of the vehicle to

Gearcase Disassembly
IMPORTANT: Due to the manufacturing process, the
pinion and ring gear assembly are NOT intended to be
disassembled and replaced.
Pinion and ring gear shimming information is NOT
provided. The components are matched at the factory
which requires special OEM tooling in order to
properly assemble and shim the gears.
In the event damage to the gears or housing requires
replacement, the entire assembly must be replaced.
1. Drain and properly dispose of used gearcase fluid.
2. Remove the remaining cover screws from the rear gearcase.
3. Remove the ring gear/axle spool assembly. The bearings
are a slip-fit and will slide off the axel spool.
NOTE: Record the thickness of the shim pack
located under each bearing. Keep the shims
together for reassembly.
4. Inspect each axle spool bearing and race for signs of wear
or damage. Replace races if required using standard bearing
puller tools.
