    An engine stethoscope goes a long way in these situations, especially since you can reproduce the behavior. They are pretty cheap at auto parts stores, and will help you determine the exact location of the noise. Since it only happens under weight, and as Bierpower noted, it times with the axle shafts, I wonder if it's a bearing or gear alignment flexing in the diff.

    I had swapped rotors and ceramic pads and didn’t lube the clips. Lubed the pins. Brakes work great. A few months later squeaking like crazy. Took all apart cleaned. Lined new clips. All quiet.

    I'm actually in the market for wireless mechanic's ears. That'd make this whole issue easy to find.

    I slowed the video down and the funny thing is that it's close to the wheel speed, but not exactly. I fully cleaned and lubed the entire brake system and swapped new clips and pin boots. So far, quiet this morning. We'll see if that holds up or not.

    My guess was brakes because mine sounds like that. I already know that I need front brakes.

    I did a full brake job on the front and the sound still exists. Pads are almost new, everything is greased, new clips, new boots on the pins, but the noise is still there after everything warms up. I'm stumped.

    I threw the JK up on stands last night to investigate further since the noise is getting worse, or at least more consistent. I was able to reproduce it for the first time with the weight off of the driver's side. I also removed my front drive shaft a couple days ago to eliminate it as a possibility.

    So, I'll try to do a Babe Ruth and call my shot. I'm 95% sure it's the pinion seal contacting the pinion/flange based on where the noise is coming from. It's definitely the differential, not the brakes or unit bearing.

    It'll be up on the lift for diagnosis tomorrow, so we'll see what a couple professionals conclude.

    Turns out my assumption was correct. I replaced the front pinion seal and the issue is gone. Back to quiet... at least for a while.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
