Differential Pegging, can this be done to STD Rover differentials or only to Diff Locked differentials EG: Harrop/Eaton mainly.

What goodies are a must need to change a STD 2014 front Rover differential from a grease type to oil lubricated type.

Same question but for the 2014 Rover rear differential.

The front Rover differentials have more parts to it than the rear Rover differential (CV joints ect.) anyway, What is the spline count on a STD 2014 Rover differential for the front & rear half shafts or put another way differential internals and drive flanges.

From what i've read Harrop/Eaton Diff locks require 24 spline axels, and Ashcroft half shafts are 23 spline, have I maybe misread something. Is an axel a half shaft.

Is a stronger/stretchy half shaft a must requirement when using a front or rear Diff lock or just preferred incase of heavy right foot at times.

The same question for about HD flanges, must have or just nice incase not so skilled and heavy footed.

I'm sure i'v read here long ago someone on here doesn't use HD shafts and flanges with there Lockers but maybe I just didn't understand what I was reading way back then too

Thanks for helping clear up my confusion Regards.

If you have the centre transfer case locked its 50:50 power front to rear , lock the rear( ARB ,Harrow, detroit ,kam, ashcroft, etc) and both wheels turn at exactly the same speed, so if your going up a reasonably steep hill with both middle and rear locked, then one rear wheel gets air or looses traction, a vast majority of the defenders weight is being pushed or carried by that one wheel. Now with the 235 standard tyres it might break traction before it snaps the axle, but with larger tyres it could snap. The other thing is if the standard wheel breaks traction, you will now possibly slide back and have the airborne wheel contact the ground, it spinning forwards , while your defenders going the opposite way. The axle will have a good chance of snapping in that situation.
Personally I am lucky enough to have the last of the Salisbury rear defs and have hytuff with a Detroit ( 255/85-r16)as I have seen others in various makes do exactly the above.

Being virtually clueless on this topic, I bow to the Land Rover gurus, Ashcroft. Lots of reading here.

this looks weird to me....it appears to be a straight rack and not a crown gear.
