Have a look at the U-joints. Try to turn it physically by hand. I have seen
this on a P38 as well as a Disco 2. Sometimes no noise and sometimes it
sounds like "bells ringing". It gets worse and worse and you may end up with
oils seals torn apart and even great damage when one of those come loose on
the run. Not easy to diagnose on the sound as it changes all the time due to
the fact that the prop shaft is a hollow pipe (in toatal it covers the
length of the vehicle) and the way the u-joint changes all the time from
start to start.

Subject: [LROC Techtorque] 300 Tdi making an odd noise
--
I have a similar noise on my Td5 - it started about two weeks ago. Started
off sounding like a stone stuck between the disc and brake pads (scraping
noise) but now its just a rattle like a small bell. Jacked the landy up
and turned all the wheels and propshaft but no noise - it only appears when
driving at speeds below 40km/h and then goes away at higher speeds (or I
cant hear it). ALso had the car at the local mechanic and they cannot find
where the sounds comes from. Any suggestions welcome.
Thanks

Matt, have you checked the tappets for tightness and clearance? That could explain the ticking, but not the scraping.
I have checked the dust covers and cant find any loose, the universal joints
have no play and propshaft seem perfect. I have found the cover over the
rear diesel filter to be loose and rattling as well as one as one suspect
shock absorber. Any volunteers for being strapped to the bottom of my landy
to pinpoint the noise :-)
While inspecting the landy I also noticed a small oil leak coming from what
looks like near the turbo (landy has done 200 000km) - turbo oil feed?
You don't say if the noise pitch changes are at engine speed or road speed?
Have you checked the hand brake drum? May have dirt in it? Or the shoes may have come loose?

The noise pitch does seem to corrospond with the speed of the wheel. I
thought of the handbrake, but if I pull it up while the noise is there it
does not go away.
Thx
That Oil leak is serious, I had to replace the turbo on the TDi at about 260 KKm, and when I opened it, it was shot! If you run it too long you risk the turbo disintegrating and parts going into the engine..
Thanks. Its definately not the dust guard and the scraping noise has all
but gone, but now I am left with what sounds like small bells - very
irritating. I will be jacking the car up this afternoon ( all four wheels)
and letting it run in gear to see if I can find the problem. The thing is
that it only starts making the noise when the car is moving on uneven
surface. It also seems to make the scraping noise only when I hit a bump or
turn left and also seems more prevalent when the car is not under load. When
hitting a speed bump it seems to trigger the scraping noise and then in 5
secs it is gone - very difficult to pinpoint. Been thinking that I must
just drive untill something either falls of or breaks off!
Quick question, do you find that when driving on a dust road, you have to pump the brakes when you want to use them. The reason for this is often loose wheelbearings which allow the disk/rotor to wobble and force the pads back into the cylinders. I am wondering if you don't have the same thing, allowing the wheels to wobble and the rotors to catch the dust covers..
Anyway, good luck, and please be very careful under the vehicle while it is running on stands!

I had the LAndy on stands yesterday and as luck would have it I found the
culprit very quickly after removing the propshafts and all the wheels to
make sure its not the bearings . The problem was actually very small - the
mud shield that is supposed to be shrunk onto the Flange was loose and
spinning around on the flange shaft at the front diff. Thanks to all for the
advise and I think Pieter was closest with his advise. The advantage of
looking for the solution to your problem is that you spend time under your
landy and then notice what other maintenace need to be done!
Thx and regards
Matt,
I have used a cut off hosepipe to locate sounds in the past – put the one open end in your ear and the other all over the engine. You will clearly identify the source that way. – watch out for moving parts though!
