Re: FRONT END CLUNKS WHEN TURNING

U Joints arent turning if your in 2wheel. But It might be the bearings? Do any offroading (hopefully the answer is yes) Do you hear the noise when your creeping slowly forward? OR only on turns? What side of the jeep? Underneath? Alittle more particular? LIFT?TIRES?AXLES?ECT. I'm sure someone can help.

Re: FRONT END CLUNKS WHEN TURNING

Here is a real easy test that will help you, and the board help you solve this problem. Go out and jack up one front tire. Spin it around a few times, does it bind anywhere, can you hear the noise at all, does it grind? When you are done spining it grab it at 9 and 3 and give it a wiggle, is there any play? Then grab it at 12 and 6 do the same, any play there? Then check to see if the break calaper is on tightly. It could be that you have a bolt that worked loose, that would be a pretty easy fix. Do the same at the other tire. If you still don't find anything out of the ordernary, then repete the same procedure with the wheels turned. With the info gathered in that test your problem should be much easier to figure out.

Oh and welcome to the board !!

Re: FRONT END CLUNKS WHEN TURNING

Check your spring u-bolts. My CJ, with OME YJ springs, clunks in the front when the u-bolts are loose, especially after driving through water. Sometimes I get lazy and reuse the u-bolts after I have pulled the front end for repair or added a spring leaf or .... you get the picture. Replacing the u-bolts usually cures it. My old Rancho lift never did this but the OME springs have done it from the beginning.

Re: FRONT END CLUNKS WHEN TURNING

I had a shackle bushing that was worn out and it did the same thing. I bugged the hell out of me until I finally found it. I tried u-joints, u-bolts and even bearings. [img]images/graemlins/crazy.gif[/img]

Re: FRONT END CLUNKS WHEN TURNING

Klunking is a pretty serious sound. When that front axle's rotating a bizillion miles a minute and is freezing up at the same time some very serious problems can occur. Klunking is the symptom... but it won't be the end of the matter.

Soon, if it's not fixed, you're going to start seeing the front fender lifting and falling as the joint gets worse.

My simple <font color="red"> Rule of thumb for sounds for the front end</font color> :

Klunking:
Over bumps = Ball Joints or Pitman arm Joint.
On Turns = Front Axle U-joints.

Wheelbearings tend to rasp and grind, especially corners and at low speed.

What more have you done to diagnois the sound?
