I just did the 10 hour service on my Maverick. The owners manual is somewhat vague on some specifications and capacities. Here is what I pieced together. Might help you out fishing out the right tools:
FRONT DIFFERENTIAL:
Oil Specification: 75w-90 Synthetic
Used: Mobil 1 Synthetic 75w-90
Capacity: 17 oz
Fill: 6mm allen wrench
Drain: 3/16" allen wrench or T-30 Torx
Appeared to be two drains. I drained the bottom first. Nothing came out of the side drain.
Note: Factory oil came out clear
REAR DIFFERENTIAL:
Oil Specification: 75w-140 Synthetic
Used: Mobil 1 Synthetic 75w-140
Capacity: 11.7 oz
Fill: 6mm allen wrench
Drain: 5mm allen wrench
Note: Factory oil came out cloudy
GEARBOX:
Oil Specification: 75w-140 API GL5 Synthetic
Used: Mobil 1 Synthetic 75w-140
Capacity: 15.2 oz
Fill: 15mm allen wrench (Plastic bolt)
Drain: 13mm allen wrench
Note: Factory oil came out cloudy
ENGINE:
Oil Specification: 5w-40 Synthetic
Used: Shell Rotella T6 Full Synthetic
Capacity: 2.3 qts
Drain: 17mm
Note: Factory oil came out clear. Oil filter pukes all over the water pump and side case on removal. No clear shot to drain. Easier to access by removing factory skid plate below and accessing oil filter cover from under the unit.
