discovery differentials
« on: May 05, 2005, 20:55:29 »
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.

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

when i broke my steering arms I had mr aa man tryto get me on a trailer but it wouldn't work without some serious lateral thinking as when he winched it on it steered off the other way!

We got the back wheels (which were goin on first) on some plastic thingies and pushed it hard sideways as it was being winched on - much fun!

He was a very nice man though - got him driving his low laoder down the first part of a gravel track that lead to a lane.. he told me they normally get stuck ona single blade of grass, so cudos to him!
