Hi,
Both my TD5 Engine mounts were stuffed and I changed them out. How smooth it is now, gearbox clunk gone as well when it changes gear but then I realised that I had a "Drone" as well.
Back under the Disco I discovered that the exhaust had what I thought was too much East - West movement when pushing the tail pipe and the main muffler. This led me to the rubbers that suspend the exhaust system.
Two of them had splits in them allowing excess movement and I heavily suspect, resonation of the exhaust system at certain revs. Also since I fitted the new engine mounts lifting the motor back to correct position in the engine bay the bend in the pipe going over the rear axale could actually knock on the Watts linkage nut on the passanger side.
This now explains a intermittant knocking sound that I had when turning right that I have been trying to pin down.
An oxy down at the local tyre shop on the back pipe bend and a bit of pressure along with some new rubbers to suspend the exhaust system and all I hear now is "The wind rushing past the cabin".
Oh, so quiet and an absolute pleasure to drive, along with the two new engine mounts my sanity and love of my Disco has restored.
I need to also point out that the origional centre muffler has already been replaced on my Disco with an OEM "Vortex" muffler. This mod alone gave a 20% reduction in fuel usage plus added more power to the Tombraider ECU Remap plus it was as quiet as the origional.
Now to the, dare I say it...no I won't....Shopping Trolley (front end reco needed, what fun).
One extra happy, Disco II TD5 driver :D
