The first LT95 diff's were limited slip in the Range rover & then they went over to normal diff's. It lists the limited slip in the haynes Rangerover manual, so pretty rare id guess. :?: Should be easy to fit though if anyone wanted to go down that route as you could change it without removing the gearbox. :idea:

Yes I agree, but why would anyone need one with a centre diff-lock?

Maybe they don't want to compromise the steering which is a noticeable effect of locking the centre diff....

But if you were to lift a wheel, on a steep decent for example, you would go into virtual free-fall!

Surely that's the point of a limited slip diff - it'll lock up when it needs to!

Yes you are right, i was thinking or torque biasing differentials.
Why did Land Rover drop them on the LT95?

Depends on the type of LSD?

I always believed the LSD was a 'solid' diff which slipped (or unlocks) when necessary?
Probably dropped on cost grounds?

That description best fits the "Detroit Locker" A limited slip diff is free to work like a normal diff under all normal conditions, allowing proper steering etc, and only works to limit slipping when a wheel lifts or looses traction in mud or on ice etc...

I'm not sure if the LSD is for a LT95 transfer box? I was led to believe that the LT95 box was specifically designed for the 101 Forward Control and then also used on the early Range Rovers, prior to the 5 speed version. I know that Haynes reckon a small number of initial Range Rovers were fitted with LSD in their boxes but have not found anyone in Rover that can confirm or verify this! However 101 prototype No1 has been fitted with a 2 or 4 wheel selectable LT95 box, presumably in 1969 when it was fitted with its V8 engine in place of its original 6 cylinder version. The original FVRDE sales brochure also shows a 2 & 4 selectable transfer box drive train layout, with the added PT drive! Finally, I know that it was decided to fit a permanent 4 wheel drive train, with centre lockable diff to the Range Rover to handle the power and torque of the V8 engine and even then the engines were derated on the early versions and the 101s.

The serial number shows it to be the 11th early Range Rover box!

Les.

The Range Rover was in production well before the 101, so to suggest the lt95 was designed for the 101 is a little fantasy story....... :?: Im guessing it will fit straight in the standard box, but thats only a guess :wink:

I don't think it's a fantasy Pete, they were being developed around the same time but there was a fair gap between final design and main production of 101s. Mike Gould (and he should know) states in the Range Rover Anniversary Guide and the Land Rover Scrap Book that the LT95 was being developed for the 101 and was adopted for the the Range Rover.

Most books say the LSD was only fitted in the first few hundred Range Rovers before being dropped. Mike Gould reckons it was a GKN Powr-Lok and very few were fitted.

The LT95 was used in the Range Rover up to around 1983 when the 5 speed box was introduced. Also used in Stage 1 V8 and early 110 V8s up to 1985.

I'll take my anorak off now and go to bed :)

Officially, Range Rover production started in 1970 but I can't remember when the 1st Velar was built and I can't be bothered to look it up. Strangely, Geoff Miller, the Range Rover Project Engineer, couldn't remember the 2 and 4 wheel selectable drive Range Rover box but Roger Crathorne could and he was named in the 101 design team!

Looking at my copy of the Range Rover workshop manual, 1970 to 1985, it does show 2 types of centre diff. However it doesn't give any details of the early version, but only states that if its worn its not serviceable and should be changed for the later type complete with front and rear output shafts.

I recall it being something to do with Rover only having enough money to develop one gearbox for both the R/R and 101. The need for it to be squaddieproof and put up with overwork/abuse brought about the LT95, with it's somewhat less refined characteristics. It was then also fitted to the Range Rover with a few detail changes, which wee no doubt considered when it was designed.

Interestingly the 5 speed LT77 was originally a Jag box behind the 4.2 six cylinder lumps, before being used in the SD1 with the V8 etc.
