Hi All,
I have a 2001 2.5 DHSE P38 and have recently noticed that on declaration at about 20 mph downwards there is a wobble/vibration that is felt through the car. It disappears when I provide the engine with some revs.
Could this be a wheel balance or something? Any ideas? I have changed the fan belt which broke and the idler pulleys and belt tensioner arm + pulley. I also changed a wheel but it was fine until the mechanical work was completed.
Regards,
Brakes maybe? Wheel imbalances seem to cause issues from 50-60 up, so prob not an issue when you are declerating. If just received deceleration without braking then diff will cause change in sound, but probably not the vibration.
Propshaft UJ?
don't the diesels have a rubber block as a universal with three bolts in it . it sounds like a tail shaft problem thou.
That's true, the diesel has a rubber donut on the output of the transfer box, could be that starting to break up.
The donut on the rear driveshaft on Disco 2’s are a very common vibration point.
When my front prop-shaft U/Js went I got a vibration at around 30MPH. There was no discernible play in the U/J until I loosened the mounting bolts. It then became quite apparent.
