Hi there, i'm new here as i've been considering a discovery, circa '96, with the 300tdi engine. I would just like some info on the what diffs they have. Do they have viscous-coupled centre or torsen and do they have the same in the front and rear or are they just open diffs with an option of limited slip-diffs. Any info would be helpfull

cheers

'Out of the box', they are fitted with good, old-fashioned crownwheel & pinion diffs in the front and rear axles.  These are (usually) interchangable.

The transfer box has a lockable (manual) diff to provide traction off road.

Many aftermarket upgrades are available for the axle diffs such as air-operated locking, manual locking and auto-locking diffs as well as torque-biasing units.  You can also replace them with strengthened types.

The axle halfshafts can be replaced with stronger versions if required.

dave306:
cheers for the info, what type is the centre diff?

cheers

Budgie:
The centre diff is in the transfer box and is operated manually from the Hi-Low lever.
These vehicles are perminent 4WD so need a locking centre diff when off-road so there is equal drive to the front & rear axle.

Hope that makes sence.   :wink:

Oh, and welcome to the Mud-Club.  :D

And the transfer diff is handy when there are no half shafts/CV joints in your front axle.   :D
