    Default Clanking Noise--Suggestions?

    My front end has been making a clanking noise lately, but only when it is in 4wd and when I give it gas. It doesn't always make the noise. Sometimes its there and then it will go away. It happens at all speeds. What could be doing this? Any suggestions would be great.

    Type of rig? Suspension?

    If it has coils and control arms, it could be bad/loose upper control arm bushings.

    Would usually only make noise in 4WD.

    Its an 04' Rubicon. 4" procomp lift. 33" tires. I don't think it has anything to do with control arms. Only hear it when i give it gas and in 4wd. Bad bushings I would think I would hear at anytime.

    Turn the stereo up louder, or never shift it into 4WD!

    Ok, serious now. Have you checked the U-joints in the driveshaft and and axleshafts?

    Aside from that, just crawl under there and tighten every nut/bolt you see!

    Good luck!

    Front driveshaft U-Joints. Also take a look and see if you have any excess play in the pinion.

    In 4WD, the axle housing tries to rotate opposite the wheel spin, and a loose bushing can cuase a clunk that's not apparent in 2WD.

    But (now that I reread it) since it's a 'clank' and not a 'clunk' I'd vote pinion also. Some TJ's had a problem with the pinions getting loose up front.

    The ball in the cardan joint is servicable. They can be greased (some have a zerk for this, others have to be taken apart)

    You can also buy repair kits, with new ball and spring.

    Usually if it's the ball, they 'chirp' like a bird.
