When I'm going along at a decent speed and hit a bump on the road even if it's very tiny this rumble strip noise starts and the noise doesn't go away until I almost come to a complete stop. Then the noise goes away until the next bump...any one have any ideas what this could be?

Sounds like front wheel bearings. If the rumble goes in and out when going like at 45mph And you steer back and forth changing the load the front tires give back to front spindles then front bearings went out. If you have already had the front rotors resurfaced 3 times might as well get new rotors with races already presses in. and also get new bearings and new seals.


DRIVE IT LIKE YOU STOLE IT.

If it is a noice that changes based on bumos most likely ball joints or shocks or sway bar.

If noise changes based in wheel rotation it is wheel bearings for sure.

I am having a similar issue on my 1998 b4000, in 2wd I am getting a rumbling noise, it stops when speed is reduced to 20mph.

Here is what makes it unique.
I just changed both front wheel hubs(they have like 500 feet on them). If I engage the T-Case, into 4h, or 4l. the noise disappears, and to make it more unique, I do NOT have any sort of locking hubs on at the time(warranty has not replaced them yet) but this noise started before I removed the manual lockers(rugged ridge)

Could this be a transfer case issue? could it be not fully disengaging? I am really scratching my head right now..
