[Closed] Whyte bearing replacements

Got a 2011 Whyte 146S, over the last 5 months there has felt like a knocking noise in the rear wheel...you can wiggle it back and forth and it feels like there is a knock. New bearings and axle in the wheel and tried on another bike and there is no knocking...put it back in the 146 and there is the knocking is back. I think the bearings in the suspension are needing replaced.

The shop I got the bike from is no longer a Whyte dealer...does the warranty replacement need to be done by a Whyte dealer?

I'm assuming so, but if that is the case, I've got a drive to Glasgow or Edinburgh to get done...which is slightly less convenient than the 2 minute drive to my LBS.
