diff torque
[Edited on 18-1-06 by mangogrooveworkshop]
Are all freelander diff the same ratio 3.21:1 and do we know if they are all LSD.
If not which is the best freelander model to look for as I need a diff for my ZX12R
Carl
they are all 3.2 afaik but none of them are lsds hence why evey ends up puttig quaife atbs in them if they want an lsd.

are you 100% sure coosey? I heard a firm rumour that some freelander diffs are LSD.
I'm pretty sure no freelanders have LSDs as standard. We'd know about it if they did. The freelanders just use traction control instead -
much cheaper.

The earlier diff fitted to the Freelander was TVK100380, due to premature failing by the problems created by the viscous coupling siezing this was superceeded to TVK000180 which has larger journal bearings and is thus stronger.
Brand : LAND ROVER
Weight : 16.05 Kgs
It would appear that the 4x4 boys use diff lock's more than LSD's and the manufactures use traction control because it cheaper.

yeah 4x4 boys tend to upgrade to arb or detroit air locking differentials 
rather then an lsd so if none have an lsd as standard then you will
have a hell of a job finding one as an aftermarket part
imho
the centre "diff" on a freelander is a viscous coupling. Perhaps thats what you're thinging about.
frelanders are nominally RWD. If the rear wheels start to slip then the viscous coupling starts to grip and transfers some of the drive to the front
wheels.
I'm pretty sure they are nominally FWD, and when the front wheels spin the rears get some drive.
It is a transverse eng & box, so much more efficient to drive only the fronts, than have only the rears driven.
I'm pretty sure that's the case,
Adam.

Yeah the viscous coupling mentioned in Mango's quote is the centre viscous coupling. Here's a quote from the same site that explains
what's going on...
quote:
To make the Freelander handle well the front wheels are driven faster than the rear wheels. To accommodate this difference a Viscous Coupling is fitted in line with the rear prop shaft, which constantly slips. On the earlier Freelander?s this ratio difference is too great causing the viscous coupling to be overworked and thus seize solid. Once seized the front wheels fight the back wheels causing transmission wind-up this rapidly accelerates the wear on the rear diff and the IRD unit, which will cause the imminent failure of either/both. Thus be warned if you need to change your diff or your IRD the viscous coupling must also be checked and renewed if necessary to stop the problem. Look at prices below for Freelander IRD, Viscous Coupling units, and fitting services.
Carl, the 3.62:1 LSD from a Sierra is well suited to the ZX12R. With 15" wheels, it tops out at 130mph.
If it's a weight saving that you're after, you could always go for a 3.38 Sierra without the LSD.
Or if you have the money, go for Froggy's 3.15:1 LSD (Good price - if its still available) 
I think I have a 3.62 Ford LSD in the garage at home. But looking into Freelanders because they are newer and lighter. We are working for Landrover in
Gaydon soon (fell of back of a wagon springs to mine). I have asked the rep who is there today to find out what's what with the diffs. I was told
on my last visit that I could buy a brand new one from Landrover at £95.00 each.

yeah it is a viscous they're quite expensive too! have you seen what westfield are charging for a freelander with quaife
lsd!!!!!!!!!!!!!!!!!!!!
?!1300!!!!!

if you can get them at that price i wouldnt mind getting one off you aslong as the markup isnt too high.
I had a conversation today with a test engineer who works for Landrover at Gaydon today. He now knows what I want and has promised to give me all the
info and help we need.

I believe they retail at £195, so given the amound of stick it'll get on a BEC, may be worthwhile getting a "legit" one with a warranty. Just don't tell them it wasn't on a freelander.

£195 everywhere ive been to wants closer to £500
ive seen the fisher ones and theirs are reconditioned according to the site (i forgot to ask Martin while i was there).
from goolgling both the part no and land rover spares and searching around the lowest price is £340+ vat and the highest is just over £400+vat..
theres a big landrover dealers near my parents house so next time i go and visit them ill try the parts dept there but i doubt itll be much cheaper

Hi All
My name is Chris Hughes, I am co founder of 2Spec Transmsissions. We Design, manufacture, assemble competition transmissions and drivelines.
We are about to start the design of a plate type LSD for the Freelander differential as well as offering fitment of the LSD and reconditioning of the
Freelander diff units.
Aimed predominantly at the kit car market we wanted to engage with the users of these units to see what would best suit them and get any feedback on
use etc.
I searched the topic and this post popped up, appreciate it is old but is the correct topic.
Is this something that the community is looking for and does the freelander CWP ratio suit peoples needs as we can look at new ratios if there is a
demand?
Thank you for reading and thank you in advance for any feedback/help you can give.
Chris
