Right rear axel makes noise - 1999 Land Rover Range Rover

You need to jack it up, And put it on jack stands. Its a safty thing. Next spin the tires with the engine, Put it in drive. let the Brake off slow. Don't forget to block the front tires with a brick, or a 4x4 or 2 pieces of fire wood. Put one under each front tire. Now run the engine 30 to 35 miles per hour.With the tires still on your Rover. Pay close attn to the noise as the tires spin. Now pull the wheels and pull the rotor or drum off. Now if its a bearing you will here it. Be sure to let off the gas pedal very slowly so you won't hurt the drive train. We checked wheel balance, Wheel bearings, Brake noise, even out of round tires can be spoted while running the tires on and off to do the test. its like driving it down the road but you can get down there and look and hear things. I sure hope this is helpfull to you.

Jack it up, and see if there is play in the wheel bearing. Do this on a flat surface with the car in gear, jack up the car, release the handbrake, grip the wheel and see if the wheel wobbles slightly. alternativly, spinn the wheel, and try to track down the source of the noise.
