what kind of noise do bad rear wheel bearings make?

Yep, increases with speed. If it goes away when you lift, it probably isn't an axle bearing (There are no bearings in your wheels) It could be a carrier or pinion bearing.
I'm not familiar with the 8.25 rear, is it a c-clip axle?
Ah yes of course, axle bearings, should have known better! Well the hood decal calls it a 8.25 but the FSM says 8 3/8" or 212.72mm for our frozen friends up north!
Yes it is a c clip type, same as the 9.25
OK, that helps constan noise with vehicle speed probably axle bearings.
Sigh, I guess that means it is the rear output shaft roller bearing in the trans. The one part I didn't replace,ugh. Guess whatI am doing this weekend?
Cheers to all
Bad "wheel" bearings on a 8.25 can make a groaning/grinding sound as you come very close to a complete stop. If your bearings are making said noise, have a good time at the scrap yard grabbing some new shafts. I just went thru this, but other than tracking down new shafts, it isn't that hard. All you need is a bearing puller (slide hammers work great) and something to drive the new ones in with.

Ick! I hate trudging through junk yards. Although thiis did give me an idea. I wonder if a rear axle out of a 94+ Ram 1500 (disc brakes!) would fit (width etc) under a RC? Sure new spring perches maybe have to figure out how to swap the Ram leaf spring ans shock mounts in, plus a new driveshaft, hmmmmmmm
If you are going hunting for a new axle to swap in, do yourself a favor and look for an early '70s (74 & earlier) truck with the 8 3/4. It's the only rear axle Dodge ever put in a 1/2 ton truck worthy of the Dodge name. The 9 1/4 has too many issues for me. It was originally designed as a C body car axle.
As for bearing noise, you can sometimes catch it early if you listen close. Frequently axle bearings will make noise on one side when going around a turn. If the left (driver's side) rear bearing is bad it will normally groan when turning to the right while driving. Regardless if one one is bad, it's time to replace them both. By the time they are making noise all the time while driving, you have probably damaged the axle shafts and can damage the housing as well.
Also, the noise I have heard most times is a groan with a vibration, similar to the sound of a set of very aggressive mud tires like Boggers. (Which is another reason I won't own another set of Boggers, they drown out all sound!) A howling noise from the rear that changes pitch with speed and depends on if you are on the throttle or coasting is frequently the usual backlash slack in a 9 1/4 or a pinion bearing that has lost preload because of the crush sleeve.
