I think it's my brakes, what do ya'll think???

Lately I have noticed kinda like a grinding noise, but not really grinding, maybe like bearings when they are going bad?!?! I can hear it when going at a very slow speed and it speeds up when I do. If I hit the brakes to start slowing down tha sound goes away. I thought it might be because I needed new pads up front, which I did, so I replaced the pads. The rotors are only a year or two old and they had plenty of life left on them and were smooth. So after the pad install I still hear the sound up front only when moving, again, when I hit the brakes to start slowing down, the sound goes away, even if the tires are still rolling...... Any ideas from all you experts out there?? Thanks

Maybe the calipers?? Plus I lifted up the front end and spun the wheel but no luck on hearing the noise. Maybe it's gotta have the weight on it?!?!

Put the front up on jackstands and check for excessive bearing play at each tire. Put your hands at the 12 and 6 o'clock positions on the tire and try to move the tire back and forth. If you have too much play (let's say more than 3/8") then you may have a bad wheel bearing.

Does the steering wheel vibrate excessively at high speed?

while your checking thsoe other things also check the dust shield to be sure its not tweaked and touching the rotors or there isn't any tiny rocks or twigs stuck between there. That may not be the problem though since its intermittent and goes away when applying the brakes but its easy enough to check just to be sure.

I had a dust shield that was completely folded like an "L" on the bottom and when I bent it back the crease of the fold began rubbing the rotor and dug in a little. Made a scary grind and squeel but Joe fixed it

Good point, I forgot about the dust shield.

When you get out of your vehicle after afew miles do you smell anything? and is your rim hot at all? Go around the front two wheels and smell.

Doesn't sound like caliper problem to me.

I lifted the front end up and checked for play as you said, No play at all. Plus when I had it up, I spun the wheels and could not hear the noise I mentioned. Still hear the noise when rolling down the road though. I was kinda thinking maybe a u-joint up front but why would the noise stop when the brakes are applied??

No vibration at all.

Checked the dust shields and they're not rubbing at all. Didn't see anything stuck between them either.

Took her for a ride for a few minutes and got back and didn't smell anything burning around the wheels nor were they hot to the touch. I could still hear the noise when I slowed down coming in the neighborhood though dangit. I did check this on my truck though and the front wheels are pretty hot to the touch after riding for a little while. The back ones were not hot at all. What would this mean if the rims were hot???

Thanks again for ya'lls feedback. Anymore ideas?? Think the caliper piston could be staying stuck out a little bit causing the pads to slightly rub, then when I apply the brakes, the pads lay on down on the rotor, in turn making the noise go away?? Just a crazy idea I just had trying to brain storm. Could this be possible, or if the piston was stuck would I have other obvious symptoms??

When I was having a problem with my driver side caliper it made my rims so hot I couldent touch them. Few miles down the road they finally got so hot they locked up on me while I was going down the highway.

I had a "bearing" sound on my 99 (brand new at the time). Thought the exact same thing, thought was brake issue. Turned out had a bad front diff bearing. Put all fours on jack stands and put in 4H and have somebody put in gear and let'em rotate a little and see if it's coming from the diff, or better yet, maybe you can rule it out. I don't think it's good to do that very long though so be judicial. But what the hell do I know, that's just how my buddy found my problem and he's a DC ASE master tech, I was just a bystander. Good luck.

You could just wait until something breaks or falls off or until the noise becomes so loud it becomes obvious what it is.

when I call my mechanic, Joe, for advice on what to check about strange noises I'm hearing from my jeep he tells me to put it on jackstands and use the process of elimination like what your doing.

can you put the front up on jack stands and turn the front tires by hand to reproduce the noise?

removeing the front driveshaft and then take it for a test drive to see if the noise continues as part of your process of elimination.

then test if the noise is from the drivers side axle ujoints and pull the assembled inner/outers from that side and replace it with just a spare stub shaft and then test drive to see if the noise continues (or if you have fully assembled spare, swap those in)... if noise continues then do the same swap on the passenger side.

if you don't have a spare unit bearing you could buy one for around $75. It would be good to carry an extra one on trail runs anyway. Or buy two and install them and keep the old ones as spares (I actually did this cause my local shop was selling them for $60 each). You could remove one of the front unit bearings and replace it with the new one on that side... if the sound continues do the same on the other side with the new unit bearing.

You may also want to look for the noise at the rear of the jeep... with jeeps it can be very tough to discern where the noises are comming from while sitting in the drivers seat. so you may want to put the rear on jackstand and continue the process of elimination.

maybe youve just got a bunch clay mud sucked into the rear drums. with the front tires chalked and the emergency brake off, remove the drum (or hat if its a rear disc rubicon) and without removing the shoes, just visually check it out.

thats all I can think of at the moment.

What you described sounds like what happened with my Explorer. I was hoping it wasn't a bearing or anything like that, I started by having the brakes inspected. I was told I needed new pads and it was fixed never happened again, although I only had the Explorer for another 6 months. The guys at the shop said brakes have little indicators that will make noise when you are moving but stops when you hit the brakes. Maybe this is it maybe not.
