the 3 k was for him to basically take out every single bit of the internals and replace em all with new bits, something which i never asked him to do, when i got the estimate i rang and asked what the fook , when he told me that my own stuff wasnt going to calf (fall apart) over the next 12 months i told him to leave well enough alone, i only sent it in because of getting different wheel speeds on the dyna pack to which he replied that it was the viscous coupling was fooked and was causing the wheel speed difference,
so my point was 280 quid labour on top of 280 quid to do the viscous, fair enough he had a look inside perhaps and checked the gears etc but he wasnt asked to do that

dunno maybe i am being over the top
