Got to pin it down closer. Rear could be calipers hanging up, rear diff (check gear oil level), u-joints, and then check trans fluid and front transfer case fluid, then the engine and front end open up many possibilities.

Alright, the u-joints are fine, all fluids are topped off, the brakes are all good, just replaced the upper and lower ball joints, pitman and idler arms, tie rods are fine, fresh alignment, tires are a bit worn(but unrelated), could it be wheel bearings? Its not in the first 20-30 minutes of operation, but then after that its consistent after any stop and feels like the rear wheels just want to stop turning, like they want to catch and seize. The rear diff was low, but i did top it off. Help! I have to drive it to Oregon on Thursday!

3 common things are the hazard/flasher relay behind the glove box, the heat shield on the cat converter, and the most common is the PCV on the drivers side valve cover. The PCV may be dirty so replace it or the throttle cable has a broken plastic tie on the rear of the upper intake so it now contacts or rests against the PCV so resesure with a plastic zip tie to the little bracket on the intake (was a push pin type on the cable) - common after any work on the intakes and really annoying. Good time to check the vac lines that T off the PCV area and run over to the drivers side - 5/32" vac hose and always rot out - your hands will be very dirty when you touch them (heat destroys them).

You said the buzzing sound comes from under the truck but you did not mentioned if it was under the hood or under the truck itself, if it's under the truck close to the rear wheel on the driver side that is the fuel pump if it's making an horrible buzzing sound maybe it's time to change it, if it's under the hood, then check all vacuums hose and PCV Valves, also check every relays.

so weird - I've started noticing a buzzing noise coming from my 98 Jimmy as well in the last few weeks. I'm not sure if its the tires I put on a few months back and I've just started noticing it, or if it's the brakes hanging up or what. But very annoying indeed. Sounds like it's associated with the wheels or tires or something, because it only happens when the vehicle is rolling.

Gotta get a better description as no buzzing from the drive train- grating, grinding, clicking etc. Buzzing is all electrical or PCV related.

Turns out the noise was the front wheel hubs. Both of them were completely shot. The parts and labor were $966. But at least its quiet now.
