Found today that I have quite a lot of play in the drivers side output from the diff, as in I can grab hold of the shaft and wobble it around!

It doesn't seem to be making any real noise, but are there any people/companies in the south (M4 corridor preferably) that could take a look at it for me? I'd have a go myself but I really want to get it sorted for the 25th June and I also have got quite a lot of other things to sort as well (including a possible new engine ).

Thanks in advance!
