110 rear axle on a 90?

Hi all,
I'm looking for some advice as my 90 needs a full new rear axle. I have seen a 110 axle in good condition for sale and have heard that a 90 axle will fit on a 110. Will I be able to fit the 110 axle on my 1988 land rover 90? and if so what modifications will I have to make?

110 should be a Salisbury, springs are different and prop, probably other things too. A disco one will go straight on and give you disc brakes too if you don't already have them.

As a general rule, you shouldn’t put a 90 axle on a 110, something to do with weight ratings or something, I think a disco onto a 110 is the same.

A 110 axle should go onto a 90. 110 rear springs are a larger diameter than 90, so the spring cups will need replacing with 90 spring cups, that’s assuming they fit over the spring cup mount? The trailing arms may be different, but I don’t know. Depending on the year of each, axle and vehicle, the brakes may be different, same as the brake lines.

I fitted a 110 Salisbury rear axle to a 88" trials motor a few years ago, in place of a Range Rover axle.
The smaller 90 type spring cups fit the 110 axle as do the trailing arms and A-frame ball joint.
You will need to shorten your prop by 2" or find a shorter one dependent on your model of 90.
I fitted the Salisbury rear axle as I was sick of destroying rear diffs when trialing, if you don't abuse your 90, you may be better fitting a Discovery 1 axle.
As an aside, the Salisbury axle is blo*dy heavy, a ratchet strap over the roof is a good way of lifting it up into place.
