Title: another diff lock question
Post by: mark.yellow.series.3 on February 13, 2007, 18:29:43

i understand on the early LT95 boxes they had a limited slip diff.
and the laterones had the vacuum operated open diff.

i have ben offered on of these for nowt, but i know nothing about them. is it posible to fit this limited slipdiff in my box and have a diff that is either limted or locked? that would be good.

does anyone know?? :D

Never heard of an L.S.D in the transfer box,thought they where only in axles,they have had viscous couplings in there or as you have said manual operated locks though......

I've never heard of the earlier LT95 being limited slip either.  Are you sure that's correct?

LSD and viscous couplings are different names for the same thing I believe

Not wishing to be pedantic but I dont think they are,

L.S.D's are a mechanical friction based form of slip,where as a viscous coupling is a fluid friction based one hence the word viscous,they are also a tad more refined in there operation than the mechanical L.S.D's

I could be wrong and if I am iam sure someone will point out my mistakes if there are any  :lol:

The viscous unit is a sort of LSD, after all it limits slip, right?

The very early RRC had the LT95 with LSD in the centre diff and also IIRC had difflock full-on (if only they had done that with the B-W box :roll: ) so you get the best of both worlds.  I could be worng here but I think it was merely the case that the LSD got deleted, not sure why though :?  cost or reliability.

An LSD will not drive quite the same as a viscous though, you may feel it 'unlocking' and it will be more prone to oversteer.


Oversteer, what am I saying, get it chucked in :D

basically. work differently but do the same job, in essence...

so it can be done, ie, diff locked or L.S.D

sounds like a good upgrade
