Vibration / humming noise - need help
I have a vibration / humming noise coming from the front. It gets worse when I turn left and not quite as bad when I turn right. I can feel it through the steering wheel. I am thinking passenger side wheel bearing or power steering pump. Is there any way to tell for sure what the problem is?
It's a 1999 Durango 5.9L 4x4.

It sure sounds like a wheel bearing due to the getting louder and getting quiter depending on which way you turn. Can you tell if the ps pump makes any noise at idle? While in park rev to about 2000 RPM and and turn wheel side to side and see if the pump whines at all. If it is 4 wheel drive you can lift the vehicle, put it in 4 wheel drive and drive, and let the wheels turn while you listen with a stethoscope at the wheel bearing. Listen to both sides and see if there is any difference in the volume of nosie being produced and if there is any abnormal noises. If you can get the front two tires off the ground you can unlock the steering wheel and shake the the front end down. If you don't have access to a hoist lift from lower control arms. Grab wheel at top and bottom and shake up and down. 2 wheel drive should have very minor movement up and down while 4 wheel drive should have none. Any questions hit me back. Good Luck!!!

The rear end is a limited slip. You do this and you will take the diff out!

Yes it's true. The drive shaft can be removed on the rear but should be marked for correct installation. The front is a open diff.
Yes, you don't want to do that to a limited slip. Talk about raising hell with the gears. The idea is great but not the best thing to do on the diff's. It is better to move only one wheel at a time. Just do it manually. There are many ways to see if the bearings are going out. Heat marks, bearings, heat, movement, and just plain take it off and feel its movement.
