    I think my upper right ball joint is going bad. I can grab the tire and it moves just a little bit. I can't really see where on the knuckle it's moving, but it seems to be from the top. It does need an alignment, but I'm not sure that's what it is. I had 3 bad ball joints on my Jimmy and you could almost shake the wheel off the axle it was so bad. This isn't that bad, but I want to be cautious.

    i believe if you can grab the top of the tire and the bottom and wiggle it that way then it's the ball joint. If it wiggles in the same direction that the wheel turns then it's something else. i hoped i explained this well enough so you can understand. [​IMG]

    If the tire moves in and out or top to bottom in ANY way your ball joints need to be replaced. Like what was said before jack up the front and then grab the top and the bottom of the tire and then push and pull to see if the tire/knuckel moves. It is not supose to move at all in this direction if it does your ball joints are worn.....

    if you are goin to have it apart might as well do the ball joints...that was one of chevys bright ideas...a ball joint you cant grese...."i dont understand why it would go bad?? hum greese dosent make that much of a differance??"...sometimes i wonder what the designers a GM were thinkin when they put that together...

    Its a all day project but it will be worth it in the end...and nice to know that your wheel wont go flying off your truck while you are goin down the freeway doin 80 or more..

    FYI, there can be some movenent, it is the accepable play in the wheel bearings.

    GM did not do the design, they bought the front axle from Dana(Spicer). they may of had a chance to change
    the ball-joints when they came out with the GM Corp. 10 bolt front axle.

    Greaseable ball joints are available. Plus, if you have just a little play that could also mean they need grease :-)

    A good way to check is to put a finger in there so that it's touching both the knuckle and the axle mounting point at the same time. That way you have a contact on both sides of the ball joint. It helps then to have someone else wiggle the tire up and down, but you can get it by yourself with one hand and a hip-check. If you feel any movement between those two parts, the joint is bad. This helps to differentiate between wheel bearing play and ball joint play and lets you know for sure whether it is the upper or lower that it bad.

    It only makes sense while you're in there to replace both the upper and the lower. Autozone will loan you a ball joint press that makes the job much easier, too.

    If you can't feel the play between the knuckle, check to see if there's play in the hub. It could be a bad bearing.
