rear wheel bearings

[haggard 2hundie]

my left rear wheel has some play and a wobble , so i want to change the bearings.
question: do the bearings have to be for an 86 or will any year work thanks

your rear bearings are axle bearing and would result in the whole axle having wobble. left and right. if its just your left tire then your hub is probably loose or something.
