I believe the ratios are different from some petrols and diesels and also 'A' and 'B' series. Its a bit of a minefield. Best wait for GreaseMonkey to come on board as he would know for sure. Either that or ask the question on a Frontera Forum. GreaseMonkey is on Fronteras Owners Group

http://www.fronteraowners.co.uk/forums/portal.php

as well so it might pay you to drop in there.

one from the same model should do but check ratio first

a lot of the A series frontera's were on leaf spring so there no good

you need to look for one that is on coil's about 96/97 onwards

you could always fit a trooper one with same ratio

I would fit the trooper one, its a lot stronger.

Am I being thick here or isn't there an issue with the Trooper and Frontera diffs? I'm sure one is a slightly different size as not all propshafts fit?

The frontera and trooper rear diff are not much different strength wise just its more common to get LSD on the trooper diffs.
Fitting a trooper axle to a frontera would mean lengthening the trooper prop

strength wise not much in it, its the front trooper diff thats a bit stronger and enables lockers to be fitted

Just heard someone have issues with one fairly recently saying the prop wouldn't fit.

Hi - you'll need one thats the same ratio - without a chassis or reg i can't match it but i would say that as you have asked about an RS then its a B series - also that its a diesel 2.2 dti - as you asked if a petrol one would fit
I would also say there are 100's of these in breakers due to fuel pump failure so spares are easy -
i would also guess that the LWB and SWB have the same ratio -
You require one from the same year to be certain i would ask for the tab to be checked
hope this helps
cheers
Steve
