Re: WJ front propeller/drive shaft
 

You can just remove the driveshafts one at a time and drive it to figure
out if either is causing the noise.

Re: WJ front propeller/drive shaft
 

"Humming noise" is often a wheel bearing. I have heard propeller shafts
making what can be described as vibrations or humming, but only at higher
speeds than you mention. Take the shaft off and check for binding and play
in the joints. When u-joints start to go, binding may be apparent before
play. Before buying a new propeller shaft, check with your local parts
store to see whether the joint is rebuildable.
