Where's that noise comming from?

When I bought this WJ it had a rubbing noise somewhere in the front. It sounds like the passenger side wheel. It's not a constant noise, it increases in speed as the vehicle speed increases. I just changed the CV joints up front and had the wheel bearings off. They were smooth as silk, no noise. Yet I still get this strange noise. The weird thing is, it's more pronounced when coasting, almost nonexistent when on the throttle. It's not a bearing noise, more like a rubbing pulsing noise. On the highway it can be quite loud, under 30mph it's barely audible.

When I replaced the CV's I saw the caliper slide pins had rust on them, could the brakes be dragging on the rotor? I know my rotors are warped, and I have the Teves calipers. Could the brakes dragging make this noise? I do have to hold the steering wheel slightly to the left to keep it moving straight, I thought it just needed and alignment, but now it seems more likely that the passenger side pads are dragging. but it's weird how it doesn't make the noise as much when on the throttle.

I can get a camera tomorrow and try to record the noise on the highway. It's just hard to explain the noise. It's a pulsing rubbing type noise.

There are no dust shields on it.

I'd say it's possible that a caliper is dragging. Can you tell any noticeable difference in pad wear? Any leaking brake fluid on that side or anything?

I'm looking through Napa's site and they have "Caliper hardware kits" The front kit appears to include two rubber slide pin boots, and two metal pieces. I have those metal pieces on my rear calipers but not my front. Are those supposed to be on my front Calipers? What do they do?

These are the metal pieces.

They help hold the brake pads in if I remember right, but I don't remember which calipers they are on (Teves or Akebono)

When I took the front calipers off, the pads on that side just fell out. I thought that it was strange nothing holds the pad in, but figured it was just how it worked. If nothing is holding the pad will that cause it to rub on the rotor?

Hmm, I know they are supposed to sit really close on the rotor and ideally they adjust themselves as the brake pads wear but if they are too loose in there then I'd say it could cause problems. I want to say they usually slide around a little though so I'm not positive on that

Does anyone know for sure what those metal bar things do? Should I go buy them and install them?

It's dark now but if you don't have an answer I'll try to remember to check tomorrow after class if I have them and remember what they do

I found a thread on Jeepsunlimited,

http://www.jeepsunlimited.com/forums...d.php?t=732726

And I did go out and check my calipers and I have two holes where that bar should be. You won't have it because you have Akebono calipers.

I still don't know exactly what they do though. I guess I'll buy these and lube up the pins tomorrow to see if that helps with this rubbing noise I'm getting. I talked to kolak and he wants $260 for new Akebono calipers, hardware, and pads. It sounds like a pretty good deal, so I'll probably buy that kit when I have some cash.

Sounds good, glad you found the answer. I did the brake job on my Jeep and my mom's 02 WJ (which had Teve's) at the same time so I couldn't remember which one of us had the stupid clips :

If that kit isn't too expensive it may be worth it anyway, I know those slide pin boots get brittle over time
