hello and thanks for the replies
after much consideration i decided to give it a go myself. I thought anything i take off i can put back on so i cant do much wrong. I also (just out of interest) phoned a few garages for a price. The tyre place I use quoted me £15. few local gargaes said no more then £20, National tyres made the oooo errr noises and then said 2 hours labour £90. REDICULOUS. Only problem with the cheaper prices is they could not do it till friday.
Anyway at 3.30 yesterday afternoon the car got jacked up and by half 5 i was done. Although most of this time was spent searching for tools and how to's on here, cups of tea and talking to neighbours. so all in all a good day
and for anyone wanting to know the stud cost me £2.46
Thanks to all who replied
Joe
