Noiseyrumble from backendhave had new bearings fitted?
Check your lugnuts first. Then jack your vehicle and grab the tire and try to determine if there is play in the new bearings. Spin the tire to see if there is a wobble in it. This would indicate a lopsided installation of the bearing. A cupped tire is another possibility; the tires surface wore unevenly from the worn bearing. You could also have a lopsided rotor which is the result of a bad bearing race.
If you do not have a one piece Sealed Hub, you have to grease and install the new bearing and race properly. If someone used a socket to draw in the bearing nut to seat the race, or forced the new bearing into place with a socket, there can be damage to the new parts.
The new bearing or race can be scoured from this improper installation. There are tools which can be loaned from Autozone or Oreillys, for proper installation. Sometimes you can use the old race to drive in the new race. Once this is installed, the bearing can be turned finger tight and finally use the bearing nut and socket to torque the new bearing in place. Usually tighten the bearing until there is no slack and back off 1 notch on the bearing nut. Then feel for slight play. There should be some play.
If you paid someone to do this job for you, take it back. You can check the tires yourself. If in doubt, change a rear tire with the spare and see if the noise goes away.
