Snapshafts
DIR By: BenzR over

---------------------------------------------------------
Saturday afternoon, one of the busiest roundabouts in Dumfries,
half way across and lost all drive, now blocking the exit from
Tesco’s I’m guddling with levers wondering which one’s jumped
out…
Beeeep…
“Fuck off”
Beeep….
“FUCK OFF”
No handbrake… (the moment of realisation as to what was wrong,
but then, I thought there would have been a Bang?)
“Yellow Knob” moment… No!.... fucking free wheeling hubs!!!
:loser:
more foul language as I’m heading uphill with my only option now
to roll backwards against three lanes of traffic trying to get
into Tesco’s behind me
Beeep…
“FUUCCKK OFFF!” :finger:
I’ve just had my first break down in Frankie :banghead
Just over 20,000 miles since the TDI was fitted, I estimate 4000
miles of that have been towing the stupid horse in the horsebox
(1350kg load,) various off roading adventures, greenlanes etc.
all on what was the best of a grotty bunch of second hand
halfshafts, so I don’t think I have a problem, however:-
I have a Stage One Salisbury axle (3.54 ratio) but don’t want to
fit it as I’d end up with a non-standard prop.
I’ve looked at fitting the 24/24 spline half shafts into the
rover axle, R/H side would be doable by fitting a spacer under
the drive flange (series one styleee) and using the “Series”
Salisbury short shaft, but the L/H side isn’t doable, as the
“series” Salisbury shaft is too short, and all the other
available 24/24 shafts (RR/110/130 Disc/Drum) are way too long,
so that’s that idea out the window.
(buying custom shafts isn’t a ££££ option)
I could do nothing, and hope to get another 20,000 miles before
having to remove the diff to hammer the twisted shattered
remains of another halfshaft out…
Or,
my question is:- :-?
Has anybody here fitted a 24 spline diff to the rear, then
fitted late series III shafts “arse for tit” so that
theoretically they’ll break at the 10 spline drive flange end
making removal of the broken shaft easier?
I mean, does it really work like that, or do the bastards still
sheer off in the diff??
I’m lead to believe all 300TDi Discovery’s have 24 spline diffs?
:gay:
our local scrappies have a couple of 300 disco’s in, and want
£30 for a diff which I can handle, the problem is I don’t know
where there are any good late series III second hand shafts so
I’d have to buy new ones which are probably made from cottage
cheese, so did wonder if I’d be better just finding some good
second hand 10 spline shafts and leaving things as they are?
Experienced halfshaft snappers comments gratefully received
Ken.

Just a thought (I'm by no means an experienced shaft snapper, so
this may or may not be a good idea), but you could try grooving
the end of a standard replacement shaft just behind the splines,
to create a failsafe point - in the manner of the KAM HD
competition shafts that are designed to snap cleanly at the hub.
Obviously, with a normal one being made of only standard metal,
you'll end up with something slightly weaker than standard by
doing so but if said groove is not excessively machined away
then it should still be strong enough for normal use, with the
advantage of a quick and easy job to replace it when you do
over-stress it.

QED - free wheeling hubs are a waste if time and money.
20k on a questionable pair of shafts. Me, I would just fit
another good pair and watch my right foot. Oh, and bin the FWH's
so progress can be maintained if you do break one.
Your's, suffered a similar fate before binning mine.

Having had shafts snap on my 109 35 years ago and the ball ache
of removing the piece, when I bought my 88 3 years ago first
time I pulled the halfshafts out they where straight on the
lathe for an undercut. Sods law they have not broken, so go with
a good second hand pair. If you have access to a lathe undercut
them about around 1mm deep at the flange end.

Many thanks for the replies
I've taken the easy/lazy option of leaving everything as it as
and have bought an Allmakes 4x4 halfshaft and drive flange (£18
and £8)
as the shaft I stuffed in to keep my going isn't great
I'll report back as to the "Allmakes" longevity :popcorn:

Are you running an 88 or 109?
If a 109 there should be props out the for the Salisbury as they
were fitted to both 4 & 6 Cyls from S11 onwards.
Not sure if there were any deffiences between the Stage 1 and
the older axles.

I'm just about to swap a Salisbury from an S3 (all S3 109 had
Salisbury axles) into one of my early Carawagon projects.
It's a straight swap and just needs an S3 109" rear prop.
I've also got a Debender 110 rear axle, all of which had 3.54
diffs, and the diff from that is going into the S3 axle to match
the 3.54 I've got for the Rover front axle (from an early
Disco).
With 200TDi and nearly 3 tons of fully laden Carawagon, the
Salisbury is a good swap.
Just need to carry a couple of drive flanges as they are the
deliberate weak point on a Salisbury - much easier to swap than
a halfshaft and dismantling the diff to remove the broken bit in
the Atlas mountains :rolleye0012:

Given the proper use and abuse you have given you existing,
questionable shafts:

A good new pair should last a life time :smilewide:

This is what I've always done with all of mine. Turns what could
be a sod of a job into a 10 minute one.
