I'm now certain The Diff is sounding terminal.

There is a definate whirr up to 30 35 mph that wasn't there before. It
disappears after that but I suspect it because all the other noises join it
in chorous.

I'll drop off the prop as soon as chance arises and try it without but then
again it'll proabably still whirrrr anyway if not to a lesser extent due to
the reduced drag?

Could be the front prop I guess but the noise is so constant it seems more
likely to be the diff.

Then again may be the transfer box but it sound too far forwards for that.

Whats the line up on prices for aftermarket Diffs chaps given it's the 101
low ratio 5.571:1

I'm not looking forward to this one little bit. :-( Front axles got to be
all but stripped down too to get the blasted thing out.

I've just dropped the oil out and it was golden with a metalic hint floating
around.

What's the problem ? Bill at GBrovers in the states can get the bits.

The technical description? It goes "whirrrrrrrrr", yet to drop the prop off
but 99% certain it's the diff.

Let me see....er.....NO....no no no no NO!

:)

too many variables for my liking and given the milage I do (1505 in last 12
months) it's not worth it.

If it's only suffering from worn bearings it shouldn't be expensive to
just buy some replacement bearings.

I've just looked at the Military workshop manual (like is there any other!)
and it suggests I need to remove the axle from the vehicle then goes on to
talk about a spreader to remove the Diff. I'm assuming all this has to be
done before I can get to the bearings on the pinion.

Is there any reason, apart from being dammed awkwar that this little
exercise can't be done with the axle on the truck? Am I missing something?

If the diff was knackered there would be loads of metal particles ,
maybe its a bearing in the diff.

Don't think so. You can do it in situ if you remove the trackrod. I need
to make a new spreader for mine anyway, since my father kindly chopped
mine up with malice aforethought.

Bastard. My father isn't allowed within touching distance of my tools
for that sort of reason.

Not that I'm aware of, although it could be REALLY damned awkward.

This spreader you speak of, if it turns out not to be the prop would you
mind doing a x2 on that order?

Just borrow mine. In fact, since I have a horrible feeling I too have
front diff problems, why not come over here for the day for a spot of
diff building ? I want to reset the backlash in my rear diff, and
tomorrow I'm aiming to drop the pan off the front of the front diff and
see what horrors lie beneath. Still, it MIGHT just be the bearings.

Cheers for the offer , though I'm hoping I've jumped to the wrong conclusion
(fingers crossed).

Fresh back in from the driveway and it may be the UJ's at the transferbox
end. They were best described as crunchy in there movement by hand once the
prop was off. First time I've had the pleasure of a failed UJ bearing in all
my Landrovering years so guess I've been lucky thus far.

I have a pair from Richard for the old Rangie which were never fitted when I
was trying to trace an illusive rumble which was eventually solved by
trading it in ;-)

Sadly the ones I have appear to be too short.. can any one confirm the 101
ones are those refered to as Long cup rather than short cup? (See I do pay
some attention)

The prop it's self is most slack in the middle with enough moment to be of
sufficient concern in it's self too. H'mmm

Steve Parker sole me some heavy duty Hardy-Spicers which are doing great
service.

I find this wierd in the extreme, not that I am not sensitive to variations
in the noises in my series (usually betokening some repair event to follow)
never having driven a 101 how can you be so sure, my reckoning is as if
everything in my old wreck seemed smoothe there would be disaster on the
horizon :)

My rear diff is probably well past its sell by date and will give out one
day for sure, my prop shaft is not exactly smooth, but my gearbox is nastier
and naughtier than all that but what the heck if it is going to jump out
down hill what is your left hand for?

It is bloody hard to differentiate amongst all the sundry noises just what
is about to go next :)

Hopefully your right Larry!

It was just the location of the noise and the note.. it also had a sort of
ring to it like a bell with a motor inside running with heavy bearing rumble
if you see what I mean.

Bearing in mind I'm sat over the top of the front diff and the noise was
louder than the engine. The noise is not engine speed related but road speed
which to a degree ruled out at least part of the gearbox. There was also no
sensation of the rumble through the gearstick which is how I came to the
conclusion the diff was on it's way.

It's almost like it's got a set of studded mud pluggers on, If I'd not
driven him for a while I'd have sorn someone had switched the tyres for a
compound made from concrete rather than the standard brick barslick. ;-)

It's always best guess (as the fan belt/waterpump showed) unless it's
painfully obvious which usually means somethings fell off or the shrapnell
is easily identified.

Article noted cheers.

I've just come back from a drive and the whirr is still evident only seems
reduced now, perhaphs thats wishful thinking. Tomorrow I'll take Morph for a
run with the prop removed. I'm thinking the slop in the prop is now the
cause, made sloppier on our recent run due to the many occasions where
overrun rumble was occasioned and possibly accelerated by the caravan giving
us a push on overun too.

I've called GKN today and they uttered £150 plus VAT for props (each)

I note the club ones are listed at £98.60 plus VAT and some utterings
somewhere in my readings that these are GKN ones.. just goes to show the
benifits of the club!

More research required me thinks and NO i'm not looking at any more
Portals....much.
