Bad Front hub bearings OR ball joints?

Hi all,

I have play at 6 and 12 on my front tires, 3 and 9 is fine.

Is that the hub assy or ball joint?

From what i can tell its the hub assy but i want to be sure before i get to work.

I would go with hub assy. It's alot easier to do that first over BJ's too

You might as well pull it apart and then go from there. My vote is actually for the ball joints...if they are bad you should be able to tell once you have everything stripped down to the knuckle.

I would say ball joints too, but it's hard to know until you get down into it.

If there is play at 12 and 6 it sounds like a BJ or two are bad. But it could be the hub.

hub is side to side, bj's are verticle for the wiggle test.

gonna have to say it's a balljoint or two.

stripping it down to the bj's is easy enough and you can get a good feel for them with nothing on there.

Not necessarily. You cannot say its the ball joint if it wiggles while holding at noon and 6. It could just as easily be the hub.

Best thing to do is have someone else wiggle the tire while you watch where the slop is being introduced. If its bad enough, it will be obvious.

Something else that can sometimes help diagnose a bad hub - try rotating the tire by hand and see if you feel or hear anything abnormal.
