I knew that my car did shake a bit when travelling on uneven roads ( 19inch rs4 alloys ) but i noticed today after 50miles of driving in sunny weather ( for once) that my car was making a strange noise when turning left or right, it felt like something was about to snap from underneath! It also make weird noises over bumpy roads like never b4! (afterall it is a 2001 tdi model with 90k on the clock)

Can anyone tell me what the damage (driveshaft?) is likely to be and the rough cost of replacing the worn parts?

And why does it always happens wen you have a small budget aside to do your car up for summer!!!
