Thread: Swap Defender diffs with discovery diffs

Interesting that it was 12mm on the one you measured. Maybe the springs sit a bit tighter to the outside of the rails on a 110 which allows for the other few mm. Or maybe its in LR's chassis build tolerances!!

I measured directly over the spring perches on bare (no body fitted) chassis.

Have just now compared to chassis alignment figures given in Land Rover manuals (see cropped pics below) and they were within specs.

The 110 measured 990mm centres - should be 990 to 1000mm (see dims 20 & 21 in figures for 110 below - Section X-X)

The rangie measured 978mm centres - should be 973 to 983mm (see dim 36 in figures for rangie chassis - Section X-X)

finally swapped the rear defender diff with the discovery diff now the only issue i have is the prop is 2 inches short would it be okey if i would add a 2" spacer in between the coupling coz where i live i would have to pay a fortune to get a longer prop

How can i identify the discovery diff i have is from which series

It will be series 1 Disco. To work out the splines... ie 10 or 24, remove one of the rear axles

I have finally started fitting the front diff and was wondering why and wut the power cable coming out of each side of the diff

Maybe ABS brake connection wire.
