Diff ratio Sierra 2.3 D L estate?

Does anyone know what the diff ratio is for a Sierra 2.3 D L estate?

I have been told that the saloon is 3.38 but on some models the estate has lower gearing (higher numerical ratio than the saloon).

I think most 2.3D were fitted with the 3.38... Like mine http://www.mnrvortxr1.co.uk/preppgtwo.htm

Some have found the early estate diesels with 3.14 though... Gold dust though.

You building a BEC or CEC?

The only way to really tell is from the tag on the diff. the code on the VIN plate should give you a good idea if it's not been changed.

Box 10 - Axle
M=3.14
A=3.36
U=3.38
V=3.62
3=3.64
D=3.92

A quick search on diff codes will help.

isnt that u and v the wrong way round?! it is, v is 3.38 and u is 3.62.

Thanks for the replies guys but can anyone confirm which is the correct code U or V for a 3.38 diff.

I went back to the earlier posts but the link given did not work for me.

I had also heard via Marc Norden that some of the 2.3Ds had a 3.14 but for the 1.6 petrol models the estate is lower geared (3.92) than the saloon (3.62) so I was concerned there might be a similar situation for the 2.3D.

I am also building an R1 engined Vortx RT though as I have no space for a donor car I have bought most of the bits off MNR but the diff is proving a problem so having to look at other options.

i can assure you, i have broken cars with both U and V on the chassis plate, U is definately 3.62 and V is definately 3.38. The best way to be super sure though, is to find a 2.3d and look on the vin plate. It will almost certainly be V, and equally, will definately be a 3.38 or (more rarely) 3.14 diff.

Having said that, i offer no guarantees!
