my troublesome xj6 tdvi with a vibration

[lionel399]

now starting to pull my hair out and thinking of selling my lovely XJ6 now. It's been in and out of garages for a vibration that you can feel through the steering wheel. It's mainly when you are doing around 65 mph. i have had new tyres front and back had new discs and pads had all suspension checked and had a front wishbone changed. Had all the balancing checked still no change .I have been told by a mechanic that it is not the drive shaft or the diff ..now been told it could be the tracking ? Would the tracking being out cause a vibration ..any ideas would really help thanks. Lionel

i have been told that it could be low on automatic transmission fluid and that could cause the vibration any thoughts on that please
