Just bought a 1995 Dodge Dakota 4x4 in Feb and it started making a humming noise in the front end and gets worse as the speed increases. It has 110,000 and a 318 motor. Tried revving the engine while not moving and it makes no noise so not the engine. Tried putting it in neutral while moving and it still hums. Seems like its coming from the front wheels? The front drive shafts still turns when it is disengaged. I know Chevy 4x4's don't do this but I don't know that much about Dodge. The tranny fluid is about 1/2" above the full line. Could this cause a problem? It is REALLY noticeable when on the highway. The higher the speed, the louder the hum. Only makes the hum when the wheels are moving. When you take your foot off the gas tho, there is no drag. It just coasts along but still hums. Any ideas as to what it could be? I just replaced the front brakes and it has new tires (only 3 weeks old for both?).
I have a 2002 that does the same thing and they tell me it's the front wheel bearing. On mine I have to replace the whole hub assembly which runs about $175 I'm getting this done on Monday not really hard to do but I don't have the time myself. I also have a bad boot on tierod end. My problems started when factory replaced that ball joint under recall also. Hope I helped I'll let you know if that took care of my hum in a few days.

Yes, someone else also told us it was the front wheel bearing. I need a larger size socket to take it off and will be doing that this weekend. So you say the whole hub has to be replaced? Thanx - will look into that. If I can't do it I've got a good repair guy I can take it to.

Just returned from shop and that's what was my problem causing the hum. The hub -- which I was lucky wasn't ABS brakes - cost me $150 and while he was doing that I had him replace the outer tierod end also which had a broken boot. Whole job cost me $300 I can live with that. They had a hard time getting the old hub off (lot of heat and a BFH) but that is a good place to start

Yes, that was what was wrong w/my truck too. Replaced it yesterday. Wasn't that hard to get off but it cost $197 for just the hub for the 1995! Oh well, at least it's quiet now!

I have to replave my hubs because of broke studs for the wheel and found them for $96.00 at am-autoparts. Com and will replace myself. But it is usally the bearings that are making the noise check to make sure you replace the hubs for no reason just the bearings. Have them show you the wear on the hubs first before replacing you will save a ton of money.
