Suspected blown motor mount 300tdi

Have a new vibration on the rover, I'm thinking motor mount (I guess technically possible its a trans mount too) due the the excessive vibes really being bad while on the go pedal and me recently greasing all the propshaft ujoints.
Thoughts?

The engine mounts don't usually give lots of vibrations through the vehicle, unless the rubber piece has totally dissapeared and it's "metal on metal"


What does give vibes though, are the UJs when they're on their way out.... eventhough you've just greased them, if there is a duff bearing in one of them, then that'll cause issues.

Also, check the sliding joints, but i'd go for the UJ's myself.

Danny, chock the wheels and put the transmission and transfer case in neutral and release the hand brake. Get under the truck with a pair of gloves on and push/pull on the driveshafts, making sure they rotate freely (any binding will make them feel tight when they are not). If your u-joints are going bad you'll feel play. It should be pretty obvious if you are feeling it under acceleration.
