Please Help Angry Sparrow Type Sound

Hello everyone I have an angry sparrow type sound coming from my jeep predominantly sounding like driver front area. I thought it sounded like a wheel bearing so that is where I started. The sound is only heard from 25ish-45ish MPH. It does not matter if I brake, turn, put in neutral and coast or accelerate it is still there as long as the jeep is rolling in that speed sweet spot. I tried sitting in neutral and raised the RPMS to around 3000 and it was quiet as a mouse so it has to be suspension drive train related I would imagine. The Jeep is my only ride and I have my one year old with me all the time so I really want to make sure she is safe with me. So far I have replaced


1. Driver Front Wheel Hub Assembly
2. Driver Front Brake Caliper
3. Front Rotors / Pads
4. Removed Front Driveshaft and drove around still made the sound
5. Removed Wheel Center caps and drove around still made the sound
6. Also checked shields around rotors and they do not appear to be making contact but that is the sound I imagine this would be similar to


Any and all advice is welcome. Thank you in advance

Maybe a dry wheel bearing? You mentioned removing and replacing a few things but I didn't see where you removed, inspected, and greased the bearings.

Dang I thought he OPDA was not an issue prior to 04? The front axle U joints appear to be in good order seals visually in tact, no clicking or binding, no free play from what I can tell. I plan to remove rear drive shaft and run it in 4hi to rule out the rear shaft tomorrow. The front driver wheel bearings have been replaced I guess I should just replace the passenger too. I think the rear are fine I can't produce any play or sound from them and they are much more labor intensive to just shoot in the dark VS front hubs I can do in hour or less.

Fill out Jeep Information in Public Profile. I believe there is a sticky at the top of the page that explains it.
