***PLEASE HELP***2001 expedition with shrudder/rumble strip noise

[n.shift]

I have a 2001 expedition rear wheel drive with 113k miles. it has what sounds like rumble strip noise but only at very slow speeds or accelerating from a stop and turning left or right. its worse when turning right.. I had a bad tie rod on one side and bad ball joint on other. I went ahead and changed all upper and lower ball joints and inner and outter tie rods. had alignment done. noise is still there. It seems to get a lot worse the more you drive it. So I'm assuming heat is making it worse. Any info would be greatly appreciated. thanks in advance

Check your tires for evenness.

i also get a bad vibration in front end over 60 mph. under 60, it pretty smooth. I also put 4 new shocks on it

Rear diff and/or axle bearings

To test front wheel bearings drive down the road with it making the noise. Jerk the steering wheel left than right , if the noise gets better one direction and stays the same or worse the other direction probably bad bearing.

I have an 01. Had a similar problem. Ended up being bad U-Joints on front driveshaft. Not sure if yours is 4×4. But it fixed my shuttering issue.

Sounds like Torque Converter Chatter... what is the status of the Trans fluid?

Check your tires for evenness.

Agreed. I had same noise and feeling on mu Silverado. It was a huge bubble on the inner side of tire

Guess I was under the assumption the noise or vibration was coming from the rear, and you were also getting a bad vibration in the front secondary from another issue. Is it only coming from the front, or is it running through the entire vehicle? Do you feel it in the steering wheel or more through your seat? If you feel in the steering wheel then look at some of the suggestions listed in this thread. If you are feeling it though you seat then look closer at the driveline, rearend, or axle bearings. When your turning is the noise/feeling coming from the rear or front?
