Really wierd one this fellas...can you help?
 

Car is a 99 turbo. All is fine and dandy APART from this:
Car runs ok from cold. clutch judders a bit in the cold, seems fine after a bit of a drive, read loads abou this and recons that is normal.
Went down the Gatwick last week from Nottingham and when i got there going in to the car park slowly going round the tight bends around 5 mph all i can hear and feel is a bump, bump, bump, straightened out the car and it goes away, same in reverse, cant really tell if its the front or the rear just underneath !
Obviously the cars hot, and didnt clog it as had the mother in law in the car, recon we stayed about 80 all the way so no hard driving.
Also got a lot more judder when it was hot too.
Had the clutch done around jan this year so wouldnt think its that?
Feels like some one is banging the underside of the car ! When you turn the wheel for a tight low speed corner ie parking up it thumps and lerches slightly.

Sorry to ramble on but its really wierd. Read in here about the diff oil and cv;s etc any help greatly recived.

Any one?
