wheel bearings

[sickvrcommodore]

hey ppl i just brought a 1995 vr v8 commodore berlina wagon it had a few little niggles like the bushing in the z bar and brakes..i replace all that and now i find because the z bar bushing where so screwed so bad for so long that all the weight and pressure from applying the brakes has nearly collapsed the passanger side wheel bearing do u think i should replace just the bearing or the entire hub?

its a sealed unit...replace bearings = replacing hub
