Grab the tonearm by the base with one hand and with the other the tonearm tube and giggle it slightly on the vertical than horizontally . If you feel no play or movement your good to go . If there is play in one plane or the other bearings need to be checked . Thats all to it . Rewiring is another thing .
Another way of checking bearing integrity ( normally the bearings are the only thing that needs to be checked ) is to put the tonearm on zero tracking force and while its floating give it a very slight push . If you see while its moving it gets slightly stuck it needs its bearings to be checked . If it just keeps on moving fluidly bearings normally are ok . Your good to go .
