Handy enough to do, check Haynes, they are great for it, have my g/box in my garage atm with the car up on stands in the garden..so I'm fresh lol
Basically, disconnect battery, all sensors...speedo, reverse light, etc etc, remove air box, disconnect gear linkage (under the back of the box), drain box oil, remove front pipe from the exhaust, take hubs off the shafts, pop the shafts out, un-bolt it and Bobs your uncle,
I'd HIGHLY recommend changing the clutch while you're a it
Best of luck :thumb:
