During a recent 'snow/ice storm' in Portland and frequent use of the 4x4 hi and low, I wore out my passenger hub bearing unit. I knew it was from the 4x4 because after the thaw, I had a severe wobble/clank from that wheel.


Long story short, replaced it, it went away. Now, when In 4hi, the drivers front wheel hums, even at a low speed. Not the type of hum you get from freeway speeds, but as though there is some sort of tension that's creating noise. Again, it's only when 4x4 is engaged. I'd like to know if it is the hub or if it's the 4wheel drive itself.


There's minor play in the steering at high speeds in 2wheel from my control arm that desperately needs replaced but no play in the wheel itself when it's in the air and I wiggle it back and forth. I would reaaaaallllyyyy like to avoid the shop since just last week I had the tranny rebuilt ? Any insight is appreciated. P.s., there's 240k miles on this rig...except the trans!
