rear arm bearing?

[1-1dicky]

iv had this problem for a while now, when i go round right hand corners roundabouts ect i get a sort of knocking sound also when i brake doing over 55 ish i get a vibration coming from the rear left same side as the knocking, iv checked wheel bearing and all is fine, now im wondering if it could be my swing arm bearing?

thanks

do you have excessive camber on that wheel?

no i dont, it all looks fine, and drives fine,... well until i come to braking at roughly 55 then it shakes from rear left i had my car up on the ramps friday, couldnt see any thing out of place or feel anthing out of place
