How can you tell if your lower ball joint is bad on a super duty?

    I took both of my trucks (06 250/5.4, 01 250/7.3) in to a couple places to check front suspension see if anything is in need of replacement.

    Belle tire says...front passenger lower ball joint on both ($500 ea)

    Harolds Frame shop....everything is good

    Master Auto...01 passenger lower ball needs replacement

    How do I know who is right and who just wants my money?

    Check your warranty first. I had mine go out right at 36,000 miles and the dealer replaced them for free. I also raised hell with them because there was no grease fittings on any of the ball joints. As far as I'm concerned that's a big no no for maintenance purposes. So they put aftermarket ones on (with grease fittings) for free.

    Jack up the front axle so the wheel is off the ground, try to move the wheel left and right, then try to move it back and forth/up down. it shouldn't have any give or play to it. if it does you know they're bad. Also as a result of the ball joint being bad, if it is bad, the inner part of the tire will start to wear and there might be some vibration when you drive. hope that helps

    Or take a 6' breaker bar and pry up on the wheel with the tires slightly off the ground, may be hard to diagnose by hand. I've had sets last 80K, one set had to be replaced at 20K. You can rent the tools for free at Autozone; not a hard job at all. You'll be a pro after one side, lots of good write-ups online.

    This is the quickest and easiest way.
    Tire shops do it all the time.

    That's the way to check them. Also, support the truck on the axle so the suspension doesn't move when you pry. Raise the truck so the tire is only an inch or two off the ground for good prying leverage. Have someone watch both the upper and the lower while you give the wheel a good up and down jerk with a long bar.
