Disco 1 Propshaft output Flange

Any tips for changing the transfers box flange on a 300Tdi to a TD5? I have a 2" lift and have decided to change to a TD5 porpshaft from Devon 4x4 (TVB 000100).
Any help is gratefully received!

Just undo the big nut in the centre and flange slids off. May need tap to assist it. Watch out of oil seal behind it. Maybe worth change that at the same time or just put a smear of rubber grease on the new flange before assemble.

There may be some lose of transfer box oil, but just top up afterwards if it is excessive.

What Andy says, real easy to do.

The TD5 prop, is that the double cardan one? Check it has grease nipples .. some don't and they can wear prematurely if used in wet conditions ..

That's great..Thanks
