Just replaced wheel bearings and ball joints on my 97 jeep GC larado and have had a hum ever since only in drive not reverse put old wheel bearing back in and still hums this is driving me nuts trying to figure it out any ideas?????
Look on the shaft of the drive axles about where they go into the axle tubes. Do you see a rubber grommet looking piece on the drive axle?
If so spray some penetrating lube on that area and then drive it. If the noise is gone it is those things rubbing.
Otherwise are the front tires cupped on the inner or outer tread? if so rotate the tires and see if the noise moves to the rear.
It might not hurt to double check the backing plates to make sure they are not rubbing. Along with that make sure it is not the brake indicators on the brake pads rubbing.
If nothing else you will need to get all four wheels off the ground and run it in drive to see if you can isolate the noise that way.

Hi my name is Allen!
I work for a Dodge Dealership. There are no torque specs for the upper or the lower ball joints on any of the Chrysler Vehicles. As long as you get them as tight as you can they will be fine, don't worry they are held in by road force anyway. Note: Be careful that you don't strip-out the nuts by getting them to tight.
For further asistance you may reach me at FixYa!

Hello Jake.
Seen this a few times in my shop.
Check the steering damper/stabilizer.
If the fluid has leaked out it will allow a kind of harmonic to take place and it won't stop until you slow right down.
The damper is like a shock absorber and it takes out that harmonic.
Undo one end of it and push/pull on it. if you feel any free play at all....replace it.
Get a good quality one as you know how important it is now.
This should cure your problem if all else is good.
Take care.
