I am told that early Range Rover 3.5:1 diffs will slot straight into SIIIs,
to replace their 4.7:1 diffs, with huge improvement to road gearing. Has
anyone done this, or got any comments or experiences to share?

Ta in advance,

SFHL

I've got a pair in Bruce with 31-10.50 x15 tyres
obviously it raises the gearing at 60mph the speedo reads
43 ish give or take 10 mph for the wavering needle
problem is off road it struggles in low box

They will go straight in. "Improvement" is a relative term - the
gearing will be too tall for 2¼ Diesel (unless you live in Norfolk),
and a 2¼ Petrol will struggle a bit. Off-road you will be going down
(steep) hills too fast in low first.

It suits some people, but not others. Personally I'd rather have an
overdrive and give myself the choice - the overdrive gives a similar
change in ratio in 4½.

depends on what you mean by "improvement". It raises the gearing
considerably. Fine if that's what you want, and yes, so far as I know,
they're a straight swap, provided you have the 10-spline type. You have to
do both front and back or things will break when you try to use 4WD, and you
can't swap one in a salisbury axle if that's what you happen to have, or
rather, you can't use a rangie one. The 110 has salisbury axle (or some do)
and 3.54:1 diff though, so that should fit.

Swapping sailsbury diffs is not a simple task like changing Rover/ENV
diffs tho.....

did I say it was? :)

however, it's the only reasonable solution if you have a salisbury axle.
Probably get someone else to do it who knows how.

Mind, there's all this talk of a special tool to stretch the axle casing so
as to get the diff out. The actual widening of the hole that results is
minimal, AIUI. What I don't know is why people don't instead attack the
thing with an angle grinder to make the hole wider.

The differential carrier bearings are preloaded by the amount the casing has
to be stretched to remove the assembly, so making the hole wider would
destroy any hope of correctly adjusting the differential.

aha. I knew there'd be a good reason, just didn't know what it was.
Salisbury axles seem to be pretty much unbreakable, so I've never had
occasion to look at one.

and FWIW, I wouldn't want 3.54:1 diffs in my series 3. Overdrive would
perhaps make for more relaxed cruising, but I'd not want to lose the low
gears.

The limit on a 101 rear Salisbury to ping it open is only 15 thou ! Then
it falls out. Anymore beyond its elastic limit and you knacker the case.
Some of the 101 club have used a piece of chain and a scaffolding pole
to wrench the diff out, in true REME style, but it isn't going to do
anything any good.

I would have been delighted to lend anyone who needs it my special diff
stretching tool, but a major arsehole at work (hi Dad) decided it wasn't
needed and chopped it up.

My 110 manual allows a maximum stretch of 30 thou, and warns about
overstretching. They also describe an alternative tool that compresses the
housing top to bottom instead of stretching it.

I've yet to injure me feet (touches wood, throws salt over shoulder) when
working wearing sandals... I did once nearly rip a toenail off, but that
wasn't work, it was moving a sofa a bit carelessly.

Feet, forearms, chest - no problems. But have you ever had a spark from an
angle grinder go up your nose?

I once saw a mechanic oxy cutting in sandals - a (large) bit of slag went
between two of his toes........ Same bloke who spent a morning electric
