warranty holdings experience

[jodypress]

i am having difficulties with the non-tvr dealer i bought my griff from re my rear diff. (technically it was a pre -existing condition) .it klonks when i reverse. i have been told by one dealer (who serviced the car days b4 i bought it) that it is a characteristic of the diff (griff 500 1996/7) and is just play, but have been to mole valley and towerview and both say diff needs to be replaced. my dilema is:- warranty holdings will only inspect if diff is stripped.
so do i take the risk or wait till it fails?

cheers

hi all
thanks for the info, have been out of the uk so no change in situation yet. i have had the car for about 3.5 months and have covered about 2500 fun and exhilerating miles.
will be in contact with warranty holdings to confirm their standing, and have had plenty of bad experiences with other warranty companies before and if they can find a way to get out of paying they will.
cheers
jody
