if only one tire stopped, the tcase isnt bad, the front diff is open, one tire can stop, and the one with more load on it will stop

Try greasing the front bearing on that side. I'm with the above, sounds like your bearing is dry or shot.

I have the same problem on my 04 edge, 2wd. The hum seems to begin at the 40 mark and builds as the speed does. freeway speeds seem to rattle the truck pretty good. Tires have been rotated since the beginning of this problem, no cure. Bearings have been checked and regreased, no cure. However, when making a left turn the hum and vibration stops. troubleshooting this has became a PITA.

Putting a running truck on a lift is not dangerous. I had mine on the lift yesterday while it was running.

I would say wheel bearing. When you are turning right, you are loading the right front and unloading the left front so the bearing has very little load on it-hence the sound goes away. Does it get worse when you turn left? Turning left would load the bad bearing even more and make it make even more noise.

My truck is doing the same thing. Sounds like I have mud tires on it, sound gets softer when turning right and gets a lot worse turning left. And there is very little play with the tire. I don't get why, but there isn't. I'm 95% sure that it is the wheel bearing.

are we going to analyze this until the wheel falls off? or is the bearing being replaced?

Bearings for my truck are like $10-15 for one, but I would need an inner and outer. I do all the work myself so I don't get labor charges and I can get deals on parts. I also have the TTB and you have IFS so the bearings are total different designs. The op I believe that I read that he also had mid 90s so he too would have the ttb.

Sorry Dr. Ranger. I'll consult you first next time. You seem to have all the answers.

Yup I know it's a wheel bearing. I would recomend replacing both sides at the same time. I jacked up my truck and tried to look for movement and found NONE. Replaced the passenger side, cause I thought that was the culprit, because when I turned left it got louder, turned right it would dissapear. Even though I change the bearing the sound didn't go away. Thought my front diff was effed, but then the drivers side failed on the way home from work. No I didn't end up in the ditch, but it was scary as hell to get the truck home. Ended up trashing the driver's side caliper, rotor, and chewing up my outter tie rod. My recomendation, if you go the sealed 300 dollar variety, go to ebay and buy them NOW, and change them. If you got the cheap ones, go to you local store tomorrow and change them. If you don't, you will cost yourself a bunch more money in the long run.

I know it's been a long time, but I finally replaced the front right bearing ***. last night. The sound is still there. It was a huge PITA, turns out the bearing is like a double bearing for the floating axle, and the inside ones were kaput. The bearings that hold the wheel on are fine, which is why my wheels aren't wobbly. The little needle bearings in there grenaded and jammed themselves in the retainer clip groove.

Now I'm scared to take the other side off for fear of the same thing happening. I'm going to have to track down another bearing just in case. My oreillys only had one in stock, and now that one is on my truck.

I have pretty much eliminated everything except the front passenger bearing though. That is if it actually is coming from the front and it's not the rear axle.

Troy -
I also just replaced my bearings. the hum is still loud as ever. Builds as speed progresses, goes away when I turn the wheel to the left... Had someone else drive as I put my ear to the floor and it almost sounds like it comes from the rear half of the vehicle. I have no clue where it can be coming from...

I'm about to just take the truck to a shop and pay them to diagnose. But that means I have to find time and take off work.

If tried changing wheels/ tires, 4wd/ 2wd, removed rear drive shaft, and it always ends the same. Same hum that goes away when I turn right.

On a side note, my ABS quit working the other day, I don't know if it's related but it is really annoying.

If anyone has any clue, suggestions are awesome.

well when the hub goes really bad the abs sensor gets screwed too. hope you find out what's going on. I got a similar problem so reading this thread made me realize what I need to do, even though the stealership done it twice, I am going to them myself. Good luck man.

I've ordered another bearing, this time from ebay for $122 instead of oreillys for $278, so I'm waiting for that to come in. Should be here in the next few days, I'll see what that does.

4x4 w/ front abs to be specific. The non-abs bearing assemblies are are a bit cheaper. The assembly has the abs sensor in it.
