I changed mine with a slight 12/ 6 play. Changed the ball joints first, problem was still there. It helped reduce the wobble known on our vehicles at 70 mph.
A couple tips. Make sure your 34mm socket is 6 point instead of 12 point. Nut is hard to break and extra play in the socket doesn't help. Order a replacement nut ahead of time. The nut is suggested to be replaced when replacing the hub, but most auto parts stores don't stock them. Rockauto sells them for around $3. I went with a Timken replacement, very satisfied.
