What i was wondering... and hoping you'd be able to help me with is, the ?bushes? i guess they are... with the steel centres move about freely like they are a ball joint or something... and in the hub that failed the warrent guy marked the one circled in red as the problem... it seems to move just the same as another second hand one i have kicking around.
The question is are these supposed to move and is it just the bigger bush (circled in blue) that is causing my problem...?
This is what the hub looks like from the back...

And the front
