Clearance under Salisbury diff?

[Kelly928]

From what I have read the clearance under a Sals is lower than that of diffs post 2002. Is it a big difference? and does it actually make a difference in terms of hang ups? If so can anything be done to improve clearance...eg grinding a few mm off.

[Slunnie]

It is a big difference.

Although its roughly 1.5" difference, that is significant as its a comparitive measurement to the vehicles that make the ruts which makes the difference.

For touring... and general 4WDing, it doesn't make a lot of difference.

Clearance under the diff is dependent on tyre size and diff guard used. Larger tyres larger clearance.

IF you are worried about the diff clearance then it is possible to improve the clearance. Distance between crown wheel and bottom of diff case is apparently35mm. Cut the bottom of diff case off, weld on say 6-8 mm plate and diff guard and you gain an extra 25+mm clearance.

Is it worth all the hassle of doing it? Rock crawling? Yes
Competition use? Possibly

Normal use/touring? Probably not

I was constantly getting hung up with mine, but going to 33" tyres made a big difference:cool:

I won't be grinding the bottom of mine away, as I haven't yet really been STUCK, I can just hear it 'touching' everynow and then:o

I agree with Leeds, Touring and normal to difficult use I wouldn't worry, it is after all a far superior differential to the P38 rear diff post 2002 defender 110/ 130. Strangely, LR fitted the rover diffs to the rear of 90's, but not the 110/ 130!! These are I believe a better crownwheel etc, but the P38 is a 4 pin. :confused:

mine drags all the time.....touring its been OK, day weekend trip doing the tougher stuff its been a pain in the rear.....

considering 255/85/16 for my next tyre

90's along with Discos and Range Rover classics used the std rover diff as they arent expected to cope with the load weights of the 110 or 130.

The Salisbury is definetely the strongest axle available, including the later p38 4 pin which was in the later ones as mentioned above.

If you have a salisbury and want to improve matters, dont change teh axle, Fit bigger tyres or 'shave' the casing. Otherwise you will probably break something

I use mine off road quite a bit and as I say to my club members, "The rear diff is the thing that stops me"
So I don't play in mud where toyos with diffs the size of rockmellons go with 35" tyres.
Otherwise it has only really held me up once when I had to be dragged down a rutted hill. Normally I can find a path that avoids the problem but it doesn't come up too often.

i cut about 10mm off mine just used a thin blade and cut from the back forward and grinded 2mm around the plug aswell as rounding off any edge .cut slow so u dont over heat the diff cover gaskett

X2 Kelvin, the 255's made all the difference:cool:

Everyone here has said what I was going to, but a quick part fix - if your diff does drag is to cut it down as the Sals has approx 50mm drag effect.

This is a quick job. I used a slim blade so no excess heat was generated to cook the housing seal.
I cut a slight angle downwards from the front after this pic so it would slide better.
The first one of these I ground away till the housing matched the coverplate but it then wept small amounts of oil due to excess heat effect.

An update to this thread http://www.aulro.com/afvb/technical-chatter/30332-salisbury-brazilian.html abaddonxi linked to is that Rockcrusher changed their name to 'Solid Axles' (and covers)
AFAIK these are still cast and made here in Australia, and it solves the chronic cover weep that occurs with the stock cover when you chop it, and the potential for it to peel away when dragged.

Get yourself one of these guards
helps slide over and protects the uni at the yoke.

Reduce clearance further again:eek::eek:

Hehe, they're only hands, "they grow back, right":D

[cinders]

G'day weeds. I had the same problem with my original tyres in getting hung up everywhere so I put on 255/85 BFG muddies and they do help a little but unfortunately these are almost considered a small tyre as 35's seem to be the norm among our japanese counterparts. So I'm finding I need to winch a fair bit more these days, due to ruts and bogholes becoming deeper, which I find a bit frustrating. But I s'pose it's all good fun!

(now where did I leave those lockers and portal axles?)

[long stroke]

Yep portal axles are the go:D

Pot & Kettle ?? :angel:

U mean fingers that's only a 4" job, the 9" grinder is for hands, neck etc..

Clearance a problem - nah :D

Photo from today - had to use the hand winch to pull her out backwards while it was hailing! ;)

Going by that pic it would,nt have mattered what diff was underneath the Fender;)

Probably not! :angel:

[Slunnie]

Yeah, a Rover diff wouldn't have dug so deep and allowed it to keep pushing through. :D Just because the axle tube is on the ground, it doesn't mean anything.:twisted:

[Col.Coleman]

Yeah my front diff seems to have a little more clearance here than the salisbury in the rear.

Double diff locked, muddies, rock crawling gears - don't mean much when BOTH diffs are grounded!

And the most embarrasing thing about it all was that I didn't have to drive into this boghole, and it was the very last obstacle of the day. I could've quite easily drove around it and gone home - but I couldn't help myself.

BUT - if I had 35's it wouldn't have happened! :p
