freelander for ford

Hi All

has any one built a chasis for a Sierra diff and then thought " sod it " and put a freelander LSD in instead???

Just a thought

The Freelander was never offered with a LSD. If you want one, it is a Quaife special...

Hi Guys

i thought it was the freelander diff that cateringham were using on their cars..... is that not atb/lsd

cheers

Yes, it's a Freelander diff but with Quaife ATB internals. It shouldn't be too difficult to make up the brackets to fit a freelander diff in place of a Sierra one. You'll also have to get some hybrid shafts made up though.

I was fairly sure they still use sierra ones on most of there cars.....


(^^ from there own website)

so I'll ask the obvious question - why do you want to fit the freelander diff ?



ps - caterham get loads of stuff made by quaife, diff's, gearboxes, gear lever........
so just because its standard on a caterham doesn't mean its a standard part

I thought the freelander diff was about half the weight , plus my sierra lsd is becoming noisey

I think i need to look into this a little further as the sierra diff isn't long enough when working with the rover LT77/V8 combi.

You can however pull from 20 to 110mph in one gear easily before the redline

not that i ever go that fast !

it is lighter, but is it going to be worth the hassle ? (driveshafts, prop shaft and diff mounts to think about)

also you'll get a quaife ATB diff for the sierra for about the same as it'll cost for the freelander


what ratio diff have you got at the moment and what would be your ideal one ?

Hi

From memory i think its ratio is 3.38 . It was from an XR 4x4 estate

i gues 3.9 or more would make for a lazier drive but im out of my depth here

mcerd1 - 26/3/10 at 12:38 PM

4x4 sierra's are normaly 3.62 (V6 & cossie) or 3.92 (2.0l)

I thought the 3.38 (7" ) / 3.36 (7.5" ) came from the diesels (not the 1.8D)


as for ratios: the higher the number - the lower the gear
have you had a play with one of the gear calc programs yet: http://locost7.info/gearcalc.php

A higher ratio requires the engine to rev higher for any given road speed, not really what would be described as a lazy drive!

got that arse about face then
