My '96 EB 4x4 emits a loud humming sound from the front end that is loudest between 40 and 50 mph. The sound goes away when I steer to the right, but is unaffected when I steer left, so I figured that it must be the bearing and hub assembly on the right side of the truck (steering to the right unloads the right side bearings). I replaced the assembly, but the noise is still there. Since my tires were getting close to the point where I'd have to replace them, I went ahead and bought a new set of Michelins...no luck.
I'm stumped at this point. Any suggestions? I did check the lubricant level of the front diff, and it's fine.
Thanks! KJ
