Vibrations and bumps :-s

Noticed a strong vibration when accelerating in my 300tdi, vibration as in buzzy and rattling the rear view mirror and dash. Sounds almost like a rear tyre is rubbing, but I've looked for signs on the tyres and there ain't none.

Also noticed when driving along that if I let off the accelerator and press it back on again that there's a split second of nothing and then a huge 'clunk' before the drive carries on.

Help!

Is it serious?

Would that be the likely cause for both issues? I kinda guessed the clunk thing would be something along those lines but the buzzy vibrations got me stumped.

yes , the clunk would be the play being aken up and the vibration would be the propshaft running ecentric

Thats ya problems, both of em , needs changeing asap before it does any more damage, ie breaking completly and letting the prop swing around

You're a star and I shall have to buy you a pint should I ever meet you.

One more question though, can I buy this part and change it by hand on my driveway or do I need specialist tools?

Ie. somebody informs me that it will require an Engineer shop to press it on.

Is that correct?

Hello flex.. I've never changed one on mine but I did recently change one on a 3 series Beamer. It did'nt need any special tools and it was very straight forward. Access was the only problem, but on the Disco there seems to be loads of room. I suspect you would'nt even need to jack it up.
Good luck.
