    Default Front end "CLUNK" on a 2006 Rubicon

    Hi,

    My name is Matt and Ive got the clunk. Its started about a year ago.... I was driving around and everyday I came home as I entered the driveway I would hear the "clunk". At first I tried to deny it, then I started to notice it more. My clunking has been goin on for some time. Ive gone to several places for help to see if the can fix the clunk and they just take my money and Id drive home and the clunk would still be there.

    In all seriousness I am trying to come up with a strategic approach to begin eliminating what it possibly could be. I have already replaced the the sway bar bushings with poly and upgraded the connectors ( http://zoneoffroad.com/blog/wp-conte...onial_008a.jpg )

    So my intention currently is to keep the jeep mostly stock as its a daily driver (and on my budget I should be driving a 1985 nissan sentra) I was thinking a complete poly bushing upgrade on everything and then start to zone in on the steering components.

    This is not the death wobble. Its just a clunk mainly when I hit a good size bump and or turn right. Ill see if I can get some pictures up to better clarify hopefully within the next day.

    Thanks again! I think this is an awesome forum!

    Matt

    If you turn right, is it just one clunk, or a repeating clunk? Is the bump clunk the same as the turning clunk? Can you identify where it's coming from (general area)?

    I have the same clunk when I come to a stop or turn sometimes. I fixed my death wobble and the clunk stayed. When you find out what it is let me know since i've been at a loss.

    Axle u joints, track bar, control arm bushings.... I would think those would be your main culprits

    Do you still have the factory ball joints with no grease fittings?
    I'll bet thats your clunk. Lift the the front by the axle, Then put a heavy rod under the tire and lift up,
    If the ball joint are lose they will make a clunk.
    Mine did out of a 2010 JK with only 9 months old.
    Good Luck

    Seriously, I had "the clunk" and it turned out to be some bolts in the steering that were not torqued correctly. Check your torque on your bolts and see if that fixes it.

    this list may help some, bvut check your service manual to see what you may need for your model jeep.

    Just gives a rough estimate. I cannot remember where I saw it, but had it saved on a txt doc just incase. Pretty sure I had it from when I was looking up the torque for the steering stuff on my 06 LJ. As always, someone should double check, but if you cannot double check this may get someone close enough to be safer than if they just tightened without checking the torque at all.

    Hey Sven, Its coming from the front right tire or so it sounds. Its usually combined meaning that if I hit a bump in a turn it will "CLUNK". When I am on flat pavement either still or moving crank the wheel every direction on flat pavement no "CLUNK". The "CLUNK" is getting louder. I may need to upgrade my stereo!
