no standard landrover that i no ever has had a LSD factory fitted, witch i think is a shame, there Farly cheap and no harder to put in, i cant see why landrover never tried it

Stig,

I think very early build RRCs had an LSD centre diff, but it was discontinued because it was fragile (and largely pointless).

I'd call the viscous in the d1 centre diff a LSD.

ditto to the Freelander 1

Because most LSDs in 4wds are useless after about 10,000km of real use

Struth, that counts out the rear LSD on my old 75 series 1990 troopie, after 350K it still managed to help me snap an axle.

Why would that be? The Disco 1 has a conventional 6 gear open diff.

MacMan is right; the Disco1 does not have a viscous or LSD centre diff.

It is a mechanically lockable diff - nothing viscous about it!

I believe the RRCs do have a viscous centre diff though that automatically changes level of engagement depending on slippage.

I stand corrected I was told all those years ago when I bought my Disco 1 that the centre diff was a viscous coupling with a mechanical lock. That explains why I was never all that impressed with the performance off road without the diff locked

Probably should have RTFM or at least the brochure that I dug out tonight to scan and prove you all wrong

As an aside the viscous diffs never were the success they were originally touted to be. I remember there were some XF utes with a special pack that had them fitted as well as the last Holden engined Clubsport but they seemed to fade away after that. Anyone know why as they seem like a good idea (Freelanders not withstanding).

Regards,
Tote
