Okay, now I'm not sure what to do. I replaced both hubs with Moogs and the drivers side CV was in good shape and a replacement from NAPA, the pass side CV axel looked OEM so I replaced it with a Duralast gold. I'm still getting that same damn noise! I'm starting to think a rotor might be warped, I've replaced brake pads, but I didn't do the rotors at the time. Anyone have ANY ideas at all!? This is driving me and my wallet bonkers!
Get your alignment checked out. I had a situation before where I got a weird noise and vibration between 45-60 MPH before, and it went away after getting an alignment. Could be an out of whack alignment.
Okay, so I was reading some other threads, and I think it might be my e-brake. It doesn't seem to be fully disengaging when I release it. This is my best guess right now. When I pull it, there is a lot of play for the the first 1/3 of the pull.
My suggestion as far as the E-brake and adjustment of it is as follows. This is what I did when I replaced my rear rotors and wanted to make sure my E-brake would hold.
1: Remove rotors
2: pull up e-brake.
3: using either a flathead screwdriver or e-brake adjustment tool [I honestly found the screwdriver easier to use], rotate the small gear on the spring. Try to find which way fans the brakes out and which side brings them in.
4: utilize the gear to reach a point where you can't quite slide the rotor back on due to the e-brake being out too much.
5: Release the e-brake
6: Try to slide rotor back on. If it slides on easily, congrats! it should be perfectly adjusted to hold when engaged only. If it still scrapes the E-brakes a bit, my suggestion is to rotate the gear one tick at a time until you can, then remove the rotor, engage the brake, and try to slide the rotor on. If you can';t quite slide it on while engaged at this point, it should be good.
7: Reassemble, find a small incline, and test by putting jeep into N and pulling up E-brake. if it holds, viola!
I can't get the damn rear rotor off! Is there a way to disengage the e-brake manually? I really think that's what's keeping it on! (No, I don't have it pulled up)
find a rubber hammer or mallet and give the rotor a good few whacks. Sometimes it gets stuck in position. A could whacks is usually enough to break it loose.then, it's just a matter of tugging it off.
Additonally, you can adjust the e-brake with the rotor off. if you look on the back side of the rear hub, you'll notice a small rectangualr hole. inside that hole is the same gear I mentioned earlier. You can fit a screwdriver in there to turn the gear tooth by tooth. This can compress the e-brake further to help, but i'd first try whacking the rotor a few times.
Okay, so I got that all done. I took the ebrake shoes off both wheels, left them off, and drove it on a private test track (for diagnostic purposes) and the noise is still there!!!! What the hell could it be!?!? PLEASE! Someone throw out some ideas!!
Are the tires new or old?
I know that some brands and some tirepatterns make it sound like you have a bad bearing somewhere.
My cooper discoverer m+s has such a loud roadnoise that you think that the bearings have just quit and walked away from the jeep..
It's weird that you say that. This all started after I bought 2 new tires for the Jeep. The put the rear tires on the front and the new ones on the rear. I thought about it being road noise, so I got the alignment done and it continued. The only thing keeping me from chalking it up to road noise is at crawl speeds (like parking lots) there is a "rotating" squeak or chirp coming from the front end. At high speeds it sounds like road whirring up until 65-70 then it goes silent. So I'm just flat out baffled as to what is going on.
I have the same problem. I have replaced both hubs & axle shafts. rebuilt both front and rear drive lines. just did a np231 trasfer case swap and the noise is still their. next is a front diff carrier bearings. pull off the front diff cover and see if their is any muck in their. yours might be the same?
I don't think this is one to ignore. It just sounds wrong. It's getting worse even at low speeds. I tried to get the sound on video. See if you can hear it on this.
I have heard that sound before and that time it was not a bearing.
It was a u-joint in one of the driveshafts that was bad making it "clunk" like in your video.
Does it vibrate when accelerating? do it stop vibrating if you let go of the gas?
Have you checked your driveshafts for any play?
I know you posted a thread about a squeal when driving, it might be that the thing that was causing the squeal has gone really bad by now.
Also while you are under it check the pinionbearings for any play by grabbing the yoke and try to move it any direction, if its good there should be almost no play at all.
Checked the driveshaft, I found zero play. About to check pinion bearings. A friend of mine (ASE Certified) says it could be the differential after he drove it. I'm guessing my diff is a Dana 30
Funny that you say that the driveshaft has no play in it and then post a vid of a driveshaft with play in it..
Or was it me not having the right name for the shaft that goes from the trans/transfer to the axles?
But fix that and everything should be quiet again (or as quiet a jeep can be)
Replace all 3 u-joints while you have it off to fix the bad one, and dont forget to replace the centering ball thing that sits between the 2 rear u-joints.
It also needs to come off to get the front one of the double u-joints to come out.
Because why not its already off the jeep at that point, might just aswell do everything at once to make it new again and not having to worry about it for a few years.
I probably said it wrong. I consider the drive shaft that long cylinder that goes from the transmission to the rear diff. I didn't think about the front shaft to the front diff. Sorry about that, but thank you for the help. Get prepared for even dumber questions on my part.
