Salisbury diff pinion waggle. sounds dangerous/expensive

Hi folks,
In short, I can waggle the back end of my rear propshaft (diff input
flange) side to side about a quarter of an inch.

I also have been (for a year or so) getting drive vibration when
accelerating or going uphill.

1. I know the Haynes manual says "stay away from diffs and get a
grown-up to look at it", but I have installed an automatic difflock
myself which needed the crownwheel and satellite gears etc removed and
fiddled with. That was 5 or 6 years ago and I've had no problems.

However I have never investigated the front half of the diff and have no
idea what to expect. By the looks of it we are talking hydraulic presses
and the like... any comments?

Is this a job I could tackle myself. ( I built the wagon from a
galv-chassis upwards 11years and 90,000miles ago )
I have no workshop facilities but a serious selection of handtools.

The wagon is a 109 SIII Stat Wag. The diff is an ex-MOD salisbury (white
cover with stencil writing on it)

Cheers

The 101 is also fitted with Salisbury's.

It sounds like the bearings have collapsed. When I fitted the Detroit
in my 101, I read up on doing the diff, and there wasn't anything too
hard, if you are methodical and thorough. You should have a DTI and a
clamp or some other good method of measuring the endfloat and backlash
in the pinion and crown wheel. You also need a new collapsible spacer,
and perhaps a new set of shims AFAIR. The crown wheel and pinion are
matched pairs I think, and the required shim sizes is stated on the end
of the pinion

You also really need to knock up a diff-spreader - to stretch the case
to drop the crown wheel out to remove the pinion. Some "authorities" say
you don't need one, and to just wrench the whole diff out with a 12 foot
scaffolding pole to provide a bit of leverage....

On the other hand you might want to do the job right.

You should also torque up the pinion to a specific drag in the new
bearings.

When I tried doing the pinion bearings on a 90 diff,
I coudn't get the pinion height right as I didn't have the right tools.
The diff ended up howling coz the mesh wasn't perfect.
I fitted airlockers to the same diffs without a problem.

I should think a 30 quid digital vernier caliper would work fine.

Cheers Steve and jOn,
it sounds a quick job if you've done it before and have the tools, but
there is a lot to get very wrong by the sounds of it.
It looks like the pinion positioning would have to be a massively long
way out before the thing locks up and explodes at high speed. It sounds
more likely that I'll end up with a functional but noisy diff.

The bit that scares me is that it's my only vehicle (apart from a push
bike)

I'll have a look just to get the lay of the land. I'll admit it.. I'm
frightened... I'll oil the bike chain.
thanks again.

It takes a real man to admit when he doens't know things and he's
scared ;-)

I'd hunt around for a spare axle myself as they're worth next to
nothing s/h - say twenty quid for the axle. Remember the costs of all
the bits you might need to do the salisbury correctly as Steve lists -
check that it's economically viable rather than swapping, especially if
time off the road is a concern.

ps Just checked on eBay, they are a few at prices I mentioned. Find
the one closest to you and go pick up :)

Or even a 11 quid one?

It's Tchibo who are selling them cheap this week.

They still do, but have joined Lidl, Netto and Aldi in doing "specials
of the week". Some of the stuff is cheap and perfectly adequate:
e.g. a load of skiing clothing just before Xmas, and a 15 quid
ultrasonic cleaning bath.

They have also opened a load of shops, including one in the town where
I work which suddenly appeared a couple of months ago.

P.S. Some specials which might be of interest to L-R owners:

<http://uk.aldi.com/special_buys/index.html>

"Power station" (small 12V Lead-Acid accumulator with jump leads and
compressor) £25

Single halogen light on a tripod £12

and more

<http://www.netto.co.uk/>

125/250kg electric hoist £40

power station with compressor £20

<http://www.lidl.co.uk/>

not much for the next couple of weeks

You missed the (from Thurs 26th):

Windscreen Anti Freeze ? 5L
* The must-have for the cold season
* 5L lemon scented frost protector for windscreen wash (effective
up to -70°C)
* Price per item
* £3.99

Can someone explain what "(effective up to -70°C)" really means?
Bearing in mind the Carbon Dioxide becomes solid at -79C...

Neighbour uses it all the time. It's actually very good and leaves
the car smelling, well, quite fresh. The lemon smell isn't as
disgusting, or chemicalised as many screenwashes... Wish I'd gone a
got a good stock of it when they had it in Aldi.

I dunno, I rather like the industrial alcohol smell some of 'em have.

I reckon this has it - but is masked by the not unpleasant cirus
bouquet. Actually, it's prolly pretty bad methanol or somesuch that
needs the au-de-leemone!

Nope, that was cut 'n paste from the web page...

Now what about the "up to -70C" phrase?

Ah, that must be the organic lemon scented screenwash then.

The flavour needs improving?
