    Default Help Ball Joint Clunk ? I think ?

    I have a 99XJ, which has a 4.5" lift on it and I am running 35 inch tires. I have started to notice a clunk noise whenever I turn the seering wheel in the Jeep I was wondering if this could possibley be bad ball joints, and if anybody has ever change them on a XJ. Any help or advice would be much appreciated.

    I have a 98 that is completely stock and have started noticing a clunk lately when I turn as well, well only left turns though... So was thinking the same thing as far as possible failure of ball joints...

    Just a few tips.... use a good ball joint press. The harbor freight one probably won't cut it. An impact gun makes a world of difference. Replace your u joints while you're at it. You might even think about replacing your unit bearings since they'll be off anyways. Make sure you use a 12 pt 13mm socket to remove the bolts on the unit bearing. You'll have to hit the knuckle pretty hard a number of times with a bfh to get it knocked off. Get replacement cotter pins for everything you have to remove. Make sure you put the dust shield from the brakes back on properly. Your replacement lower ball joints will probably be greaseable.... if they don't come with a needle zerk fitting, you'll need to find a small bolt to plug the hole. The normal zerk fittings supplied will possibly get ripped off by the ujoint/axle joint area.
    Take your time. I think the 1st side took me just over 2 hrs to do. The other side was done in half that time.
    Oh, and the dealer wanted to charge me around $900 for the ball joints, unit bearings and u joints.... I got everything from napa for under $400.

    Here's a good write up:

    Thank u all for the help But I just figured out the problem, it wasn't my ball joints thank god it was the bushings on my lower control arm that were hosed, that is going to save me quite a bit of time and money! Money that could be spent on !!
    $63 bucks at the NAPA for the bushings as opposed to 400 plus for the above listed parts!!! Sweet

    Clunks can come from many parts under the newer Jeeps.

    Control arm bushings (as you found out!)

    Track bar bushings/bolts

    Tie-rod ends

    Axle U-joints

    Ball Joints

    I had one on my '99 XJ. Found 2! My RE track bar had a bad lower bushing (only $10 from RE!!)

    And I had a bad TRE ($46 MOOG)
