Ratio and quaife for Freelander diff
bitsilly - 25/3/09 at 12:58 PM

I have found out that the freelander diff TVK000180 is the one which has been made stronger, but can anyone tell me if
1) Are all freelander diffs the same ratio?
2) What model code or name is the quaife unit to make it LSD.

Westfield sell the combined unit for £2087 but the diffs new from Ashcroft are only £431 and I think a quaife unit is around £500?? But if I aim to do it myself, I need to be sure I get the right diff ratio and quaife unit!
Help!

ps is it difficult to do??

Cheers

Freelander diffs are 3.21:1

Cheers gents,
I take it that all the freelander diffs 3.21:1 whether they come from diesels etc.

And that that quaife unit is the one for BECs, presuming it is not weight dependant ie it is still the one to get when it is in a BEC?
cheers

ATBs work in a different way to plate-type LSDs so its a one size fits all solution. I'm sure there must be an explanation somewhere on the WWW.

Early Freeloader diffs (apparently) had some bearing issues, fixed in the later ones. They're all 3.21, except some early ones which were 3.19. Land Rover had these different ratios front/rear in the early Freeloader, high probability that this nonsense created the viscous centre diff troubles, great idea huh? My guess is it didn't help the diff. bearings, but that's only my guess.
Anyway, I've ruthlessly abused the early 3.21 in the BEC with no issues.
