93 ZJ "clunk" in front axle
Hello all,
when I drive through a rut or a pot hole with the front passenger wheel I hear sort of a "clunk". Yesterday I pushed (with my foot) the top of the wheel inside and heard a pop (just bearly heard it. So I am wondering, is there a bearing there that's worn out what does that ? Well actuall what I am asking is.. How can I determine what it is ? thanks, Ron |

Oh also,
when driving at 40-60 mph, if I hit a bump just right, .. the whole frontend starts vibrating, resonating, and doesn't stop until I slow down a lot.

I'm guessing track bar bushing might be shot.

Ball joints might be going, too. Get thee to a repair shop.

You should be checking this out sooner than later, if it's a ball joint
failing your tire can fall off, same if a wheel bearing blows out. You can jack up the front and if it's a wheel bearing the wheel will be flopping around. You can go under while someone cuts the steering from side pin to side pin and watch the top and bottom ball joints. If you see vertical movement in their joints or if their is rust coming out around the rubber boots, they are about to fail. While doing the above side to side with the steering, watch the track bar that goes from a bushing on the passenger side axle up to a ball joint on the drivers side frame. If the bushing is bad on the axle, you will see movement, same for up at the frame ball joint.

That is called the death wobble....
Yes it can be caused by a bad track bar bushing or ball joint and all the other things mentioned including a bad steering damper shock.

ok...
Is that something that something you can easily fix yourself ?

Ron Croonenberg did pass the time by typing:

Something I'm not to unfamiliar with. :/ Try it at 85-90MPH. Let me guess.. hitting a bump "just right" is at a diagonal. It only gets worse. You need to take care of this before the wobble scallops your front tires or you dribble off the road. ^_^ Here is the list. (besides having too high a tire pressure) 1) tire balance/rotation/alignment (even a bad tire) (a badly balanced tire/thrown wheel weight leads to DW) If you have a bad tire move it to the back where it does less harm. 2) dead stabilizer/damper (this shock, located on the drag link, helps reduce steering vibrations) http://www.revbeergoggles.com/temp/front-suspension.jpg 3) dead shocks. If your shocks are original then they may be gone. without good shocks the suspension in a ZJ is not stable. 4) Antisway bar mounts cracked or failed. This has the effect of not damping both sides equally. http://revbeergoggles.com/swaybar/ 5) Control arm bolts loose. Check the eight bolts (four on the body four on the front axle). This takes a torque wrench to check since even if they feel tight they may be loose enough. At any rate, I'd have someone check the runout on your tires. -- -- DougW -- 93 ZJ 4.0 http://members.cox.net/wilsond HESCO Supercharger - 300W IASCA Stereo - Edelbrock IAS Shocks Gibson Exhaust - rear DCpower - custom gauge install - Stillen Rotors Banks Header - and BEER, in the fridge! |

Yes. The axle end bushing is replaceable. If the ball joint end up at
the frame is bad, you have to replace the whole bar as far as I know. That's how the rest (TJ, XJ) work anyway. Still not a difficult job. If it's a wheel bearing, that's an easy fix too, you just replace the hub on those. The ball joint is best left to a pro, it's an SOB to change.
