This noise only happens after I've driven a mile or two, and I only hear it at speeds slower than 40 miles per hour. It's kinda like "ga-RUNK, ga-RUNK, ga-RUNK." The sound is most noticeable at speeds under 15 miles per hour, and it's really, really annoying.

I think it's got something to do with the brakes, because when I push on the brakes, even just a little bit, the noise stops. As soon as I let off the brakes, though, the noise kicks in again.

I replaced my front brake pads about a year ago. I had some trouble getting the calipers to cooperate. The noise is new, though. Maybe I fouled up the right front caliper? If so, what do you suggest I do next?

I'm committed to doing as much work as I can on the Jeep by myself. Handing over cash to mechanics is not my idea of fun as a Jeep owner! I wanna learn how to wrench on this thing!

might be a wheel bearing . drive it around and see how hot it gets .

or the caliper is seized , do you feel a pulsation in your pedal when you press on the breaks , if so the rotor is warped .

Jack it up til that tire is off the ground and grab it at 9and 3 and wiggle.. If it wiggles .. Check your balljoints.. If not. Grab it at 12 and 6 and wiggle.. If that has some wiggle.. You need to replace your unit bearing...

the hub should feel hot as Brad said after a drive.. If its bad....

i should add in don't stick your tung on the bearing , in fact use some one you don't like . seriously they can get glowing , use the back of your hand to feel for heat or spray some water on it .

wiggling the tire like swampy said works well and you don't have to waste gas . Smile especially with that dahm new carbon tax coming out pissed dahm you liberals .

you could also try greasing everything under your front end , i have had a lot of annoying noises go away and even thunks just by greasing everything .

I did this test on my own zj and it appears to have some wiggle in the 9 and 3 position. The 12 and 6 has none whatsoever, so I am guessing that the 3 and 9's small play is bad, is that correct?

I've also notice that the jeep seems to 'wander' on the road - could my ball joints need replaced?

sounds like one of the brake pads has come loose
pop that wheel off and see, before you need a $100 rotor

hope this helps

You should have someone wiggle the tire while you look from behind. If there is no movement at the ball joints, you have bad bearings.

Isn't a wiggle at 3 and 9 o'clock, but none at 6 and 12, an indication of bad tie rod joint's, rather than ball-joints or bearings? I mean, a bad bearing should cause a wiggle in any position, and the ball joints, being located at 12 and 6 o'clock positions (approximately) should cause a wiggle in that position, unless I'm misunderstanding something?

Pretty much, that's why I suggested just looking to see what's moving.
12 and 6 is a ball joint check not 3 and 9.

Well I will be inspecting my tie rod joints tomorrow then. Kinda sucks that they wheel end joint isn't changable - that you have to replace the whole thing if it is bad... anyone done a work-around for this?
