help! 4wd hub issue.

terr5178 · Jan 12, 2014

Replaced d.s. hub and intermittent brrrrr noise went away. Seems as though the wheel sensor was bad on that one and kept activating the abs.
So now I'm back to square one. New hub on d.s but the original humming noise is still there. Gets louder when I turn right and lower on left turns. Rotated tires but didn't change anything. Verified 1/2 shafts are not engaged and transfer case in 2wd, front driveshaft spins free.
Humming Noise is loudest around 40 mph and causes a vibration in pedals and steering wheel... any other ideas?

Problem found. It was the rear drivers side hub causing the humming. It sounded like the front hub but after 3000 miles the humming got louder. At that point I was able to find play in the rear bearing that wasn't noticeable before.
For anyone replacing a hub. Do yourself a favor and buy a us made hub. I changed both the front and rear hubs with china made parts only to have to redo them again in 600 miles or less. The front abs sensor was bad from the beginning and the rear went bad at about 600 miles. I replaced both with timken bearings and no issues.
