Salisbury axle into Disco

Given my ability to constantly find the weakness in rover diffs, I have bit the bullet and got a salisbury axle to chuck in the rear of my Disco.

I have searched the forum for other like minded souls and a few others have looked at this option. The one thing that is clear however is that I shall require a different propshaft. Non of the previous threads have ever fully answered this point though.

Can anyone out there in clever land tell me if there is a suitable prop that can be put straight in to replace the std disco one or will I need to get a bespoke shaft made?

Assuming worst case, and I have to get something knocked up, can anyone recommend a supplier to do the job.

Cheers in advance for all the helpful comments and sugestions that will no doubt come flooding in - DV

Do yu need a longer or shorter one?

If it's shorter, Tiz easy

needs to be shorter by 30mm

So thanks to our learned friend above we know it needs to be shorter, how does that come out to 'tiz easy'

Also because its lifted and I've got corrected trailing arms which are +20mm to get the axle back to where it should be, does this need to be taken off the 30mm suggested meaning only 10mm shorter.

I would guess with an angle grinder and a welder, no?

it might fit with your +20mm arms - i have a disco axle under my 110 cos i got fed up with the salisbury forever grounding out - i had a 30mm spacer made up to use std prop and to leave enough still on the slider for axle movement

Thanks for the info, I'll get the axle under and see how the original prop looks before I get too carried away.
I assume the main problem comes when the suspension is compressed meaning the prop needs to be shorter. The rear end also has extended bump stops to limit the amount of compression so I may be lucky with a std prop as the axle travel has been limited.

yu need to fit the axle and then (without springs) find the compressed length (minimum) and then drop the axle to find maximum prop length required and then find someone with a lathe who can cut off the REAR of the prop tube and refit the rear knuckle back into the tube at the correct length and angular displacement. Then have it rewelded. Tiz easy, coz yu can always shorten a prop, lengthening it can be a bugger.

I've just read this... I've a 110 with the axle off my old 300tdi Disco. As far as I can remember we did nothing to the prop at all.

Does this mean something nasty is going to happen if I manage to compress both rear springs fully?

Incidentally, is there a difference in track between the Salisbury and the Disco, as there doesn't seem to be much clearance between spring seat and tyre on 235/85's, and I'm thinking about 265/75's?

The 110 has a Salisbury because the standard rover axle isn't strong enough.

salisbury track is same as std axle ,diff nose is longer than rover diff sa its alot heavier unit,rear prop must be welded with yokes in same plane like a double ended flat open ended spanner

I know the Salisbury is stronger, but I wanted the disc brakes and I don't normally carry a car load of rocks... but do you know if the track is the same, or is the Salisbury wider?

And will my propshaft bend?

Thank you James, I hadn't noticed your reply when I last posted (from the phone - small screen...).

So, track is the same, but if I take off over a hump back bridge the sliding joint on the prop will come apart?

I've done about 10,000 miles in it, including some pretty rough stuff, and never suspected there might be a problem.
