Hi all, my D2 TD5 has, as explained in the title, a horrific grinding/ screaming noise coming from below the car when the clutch is either fully or partially depressed. I think I have figured out the problem with reviewing all the posts but cannot find anything that 100% matches my issues (the search bar on here has stopped working for me).

Anyway, this issue is not there all the time and it does seem to disappear after it warms up but I cannot verify that 100% yet.

I have recently changed the clutch on my drive and really do not want to repeat the process however 3 things happened to me/ I learnt too late when doing this;
  1. I lost the new little black clip that holds the release bearing to the clutch swing arm so had to reuse the old one, it didn't seem warn or brittle
  2. I tried to be clever and get a clutch alignment tool that did many cars, it did not fit the discovery (and I learnt I never want to replace clutch again without a lifter)
  3. I did not release changing the spigot bearing was a key thing and only cost £1.39 if I want in a rush for the car.
If any of you experienced guys know any way to diagnose the issue without stripping it down, I will give it a go. Was considering getting a cheap endoscope and using the bell house drain hole to look but not sure I would be able see much past the fly wheel to get to the spigot bearing.
 
Mine is nearly the same, but not as loud.... needs replacing, but Im waiting till I get the clutch done....

And yes, I cant get the search function to work either. Im just searching google and looking at the Landyzone results
 
Yep, thrust bearing, should be changed when changing the clutch as its cost is far outweighed by the PITA of taking the gear box off to replace.
 
Thrust/release bearing is a different noise to the spigot bush which is common to hear on TD5's. As Op is saying its a high pitched scream, worse with a cold engine.
Assume you did the whole kit, pressure plate, friction plate and release bearing?
 
I'm guessing it's something to do with the release bearing. The spigot bush can get a bit talkative when worn but I don't think I've come across a terribly noisy one. The dual mass flywheel (assuming you have one) can get noisy on these too. When I did my clutch at the end of 2016 I was expecting to see wear in the spigot bush and release bearing because it was getting noisy but they were as good as new. However the dual mass flywheel had got loose and rattly. A new one and it's much quieter.
 
Really? God cars have got stupid recently! I would never have imagined this, but then anything is possible with dual mass flywheels!
Wonder how hard it is to change. Some of them used to be right sods in the old days!
 
If OP could supply a video I'm sure we could diag it, they are different sounds
 
Ive never heard a duel mass squeal when the clutch is depressed they usually vibrate on tick over when there's an problem
& the vibration disappears when the clutch is depressed.

When you pull it apart to inspect it use a 22mm piece of household copper pipe to align the clutch ;)

Maybe not squealing, but thy're perfectly capable of moaning, groaning and rattling. I'm not saying that's what it is, but just to make the point that they can be a source of noise, some of it more the stuff of low budget horror movies than anything one would associate with a transmission.
 
The percentage now seems to be in favour of spigot bush then, what a sod!

Release bearing usually only makes a noise when you depress the clutch, until it is fully released again. Bearings inside it are knacked but only have to turn once the clutch pedal is depressed. When released it turns with the clutch, flywheel, and input shaft so no need for the bearings to move.
Suppose spigot bush noise must come into the same sphere of influence, and be heard under the same circumstances, although I am intrigued its noise goes away again once the clutch is fully depressed, as mentioned by @tilly2. I have heard of the noise from a release bearing going away or getting better as the whole driveline warms up, maybe this is what is happening inside the spigot bush but does that have bearings in it? Needle or otherwise? Not sure I have ever seen one with bearings in it, to me a bush is a bush, but I don't know it all!
Others will jump on with this info, but still dying to know whether OP has changed release bearing or not.
 
Well thank you all for your help, it is much appreciated.:D It would seem the spigot is the issue (that will teach me to not read the manual first before starting a job)... I am lucky enough now I can take it off the road for a period of time and take my time, I will get as spigot bearing firstly and if I find the thrust bearing has thrown a wobbly (it shouldn't as it hasn't done many miles since I changed it) then I can await its arrival. I found a usefully video on the Tube of You which all though of an American origin :p helped to explain how the spigot bearing works and while it makes its noises.

Guess now I have to decide if I do this pig of a job again :mad: or pay someone £600+ to change a £1.35 part.... Maybe I can convince the misses this is a good excuse for my to buy an engine crane :)

Thanks for the confidence boost I will post a couple of other questions on separate threads, hope to see you again. I will add my findings to this thread once I have come out the other side.... don't want to leave some of you guys on tender hooks :cool:
 
I agree completely that this issue is the spigot bush.

I've never done the clutch on a D2, but I'm assuming it's the same as the previous LR's and will want a soak in light machine oil overnight before fitting - it's an oilite bush ( sintered bronze ) so has pores to store the oil .....
 
Thanks for reminding me, I remember reading that somewhere before.... heaven for bid I have to do this job again after missing something else :confused:
