That's new!! but doesn't sound good!

Maggsie8 · May 21, 2019

OK... have now got a lovely tapping sound coming from what seems to be the gearbox to add to my abnormally loud fuel pump (working on sorting that out)!! A little distressing as its disturbing my enjoyment of hearing the thud of insects hitting the windscreen on these beautiful summer days or the sound of the portable hurricane force winds that appear from nowhere as I approach 50MPH!!

Any ideas?... clutch, flywheel, the whole gearbox or something else? the tapping is present in all gears (but louder in some), doesn't really disappear when dipping the clutch, but changes gears OK (can be temperamental after driving for a while and might need a little nudge, but hey its a defender!).

Its a 2000 TD5 so has an R380 and has only done 90K... yes I know I could have a professional come out and look at it, but I thought I'd ask those who understand these fine machines first, before watching somebody breath sharply through their teeth, rub their chin and mutter the words "it gonna cost ya"

Thanks as always

Does the tap frequency increase with engine speed or vehicle speed? Does the frequency alter as you change gear?

Yes it does seem to.

Which? Change with engine speed through the gears, or road speed? Or both!?

Seems to what ? go with engine speed ? Or gearbox speed ? Or constant with the speed of the truck?

Maggsie8 · May 21, 2019

Engine speed... when sat at lights in 1st it just a low tapping and then as you pull off and increase speed becomes more noticeable and constant

kermit_rr · May 21, 2019

What happens in neutral? When you're sat at lights?

Maggsie8 · May 21, 2019

No tapping present

kermit_rr · May 21, 2019

Ok has there been any other unusual noises. Even if brief?
Bearings usually whine or grumble, a uj wouldn't tap. If it was a damaged gear on your output somewhere, it would be rather frantic. Some damage on the intermediate shaft?
I'm not really sure without a good listen! Someone else might have a better idea

Can you record a video and upload to YouTube?

Maggsie8 · May 21, 2019

No other sounds... can record it and upload to YouTube (will do that tomorrow). Thanks

If there's no noise in neutral but there is with the clutch depressed and the gearbox in gear I would begin wondering about something towards the engine end of the drivetrain. For example a lot of my funny noises disappeared with the installation of a new dual mass flywheel. Moans and groans at low speed on a damp morning, especially with the clutch down, a tinny rattle at high speed and various other things were cured. On dismantling it was apparent that the dual mass flywheel was very loose and rattly. I'm not saying it's that, but if you're contemplating taking the gearbox off, it's relatively easy to check, before you actually start taking the gearbox apart.

Thanks... definitely something to look at.

I'd have a really good look at the ujs anyways, they can make all sorts of noises. It would be a cheap fix.

Dmf can cause what you are describing

That's where my thinking is heading... I think for peace of mind it might be worth fitting a new clutch & DMF, inspect the rest and hopefully not find anything else!! Can anybody suggest somebody decent around Surrey/ Kent areas who could do this and not rip me off in the process?

If your running a tuned td5 consider a lof clutch and a luk dmf

Thanks @Discodevon, that's a good point... it has been remapped by the previous owner (although might look at getting that looked at as not sure its a good one) EGR has been blanked and I'm planning on changes hoses, etc.

Discodevon · May 23, 2019

Buy the dmf on eBay, much cheaper than the lof website
