Thread: TD5 vibration 2500-3500 rpm

I have just bought a Disco 2 Td5.
Vibration that seems to cause concern to many owners and my self.
Seems to be coming from the the exhaust header.
Construction is stainless steel, this is very hard and brittle metal.This is the cause of the vibration problem the header is acting like a speaker.
Looking at the way it is mounted it is a long way between supports.
When time permits i will be experimenting with some extra braces.
I would suggest possibly 2 braces horizontally fixed at the 3 and 9 Oclock positions. Utilux clamps and the original rubber hook arrangements will work fine i think.
If it works a visit to an exhaust fitting center could weld a more permanent fixings in place.
As stainless heats up and cools hundreds and thousands of times it hardens even more as the metal looses its malleability it tends to resonate even more.
A new header and flex joint should solve the problem as well at a cost though.

iv got a td5 and iv had both engine mount replaced and front propshaft and it still vibrates at 2200rpm any one got any ideas

Ok,
With mine the Rattle as it is better called.
I tried this.In park no hand brake on rev your engine up till you hear your rattle (mine about 2150rpm-2250rpm) hold the revs and now pull on your hand brake.
It should be adjusted so that by the 3rd click it is full on (nice and firm).
My rattle is not present if i do this, obviously i cant drive like this so on further investigation i have found that lots of the parts in the hand brake mechanism are worn this it seems is due to the vibration over the years.
I have just ordered new drum shoes and a full spring retainer kit.
I believe the noise comes from the shoes rattling on the inside of the backing plate, if you look in there you will see considerable wear at the points that it all rattles on.

It is definitely NOT as i stated in an earlier post the exhaust flange.
I have changed my engine mounts ($260) and it made it worse than before all be it at a slightly lower RPM.

Yes!
go to The Good Oil Forum!

Ok up date on my findings.
I have now replaced my hand brake backing plate and brake shoes and all the springs in the hand brake arrangement.
THE RATTLE IS GONE.
As i found on previous looks under the hand brake drum i noticed without disasembly that things were worn from the vibration of the engine (particularly the backing plate).
Now that the parts are out and on the floor in front of me it is quite obvious what was causing the rattle.
If you want the rattle completely gone you will need to replace all the components under the brake drum.
