my suspicions are the spacer got stuck to the bearing and I threw it out when I changed the bearings. I have just check Noah's suspension guide and have seen a pic of the spacer and I am missing it.
So it looks like I will be ordering a pair from VW tomorrow, hopefully pick them up friday and then fix it over the weekend.
I do hate it when these things happen.
cheers guys for your help, I'll let you know how I get on
