I have had a slight thumping sound coming from up front. it is noticable when hitting small bumps / ripples. It sounds like it is coming from the driver and psngr side. I have been thinking sway-bar or leafs. Put new shocks on within the past year. I took it to a local ford house. They changed out the ball joints. but the thumping was still there.
3 months later took it back to have all the fluids from the rad back to the rear diff changed and to check the sound out again. Nothing found.
After this service not only was the thumping still there, but a noise and vib randomlly starts (various speeds)that is very similar to the noise and feel of driving over a grooved concrete roadway. This seems to be coming from under the driver seat - floor pan forward. Back to the ford house where they now replaced the new ball joints, steering box gear assy, & drag link - n/c.
The roar / vib as well as the thumping are still there. The roar/vib clears if I switch to 4hi, slow to about 5mpg (stops like like a switch turing off light), and sometimes hitting a bump. It has also ben triggered by hitting a bump. I had to use the X today and felt and heard a small pop, like something unbinding, when slowly turning into a drive. .
I will be getting it back to the shop but it has to be something that changes state when
when transitioning to 4hi but can also be influenced by bumps or by slowing to a very low speed. I wouldn't think a bump or jarring culd influence the xfercase and/or front diff . Would a problem with the d/s clear/stop so abruptly when nearly stopping? This issue started after the fluid service.

Hi there Chris,most if not all 4x4 Excursions came with the front sway bar and if your X does have one I'd take a swing at purchasing replacement OEM sway bar bushings or get the Energy Suspension polyurethane bushings.
Perhaps Landyot or Eric will chime in with their input as they're more deep into suspension than myself

I have not been under my X in the front end yet, but on my Jeep I have U-joints instead of CV joints on the front end that have gone out twice. Had clunking and poping sounds from them when I hit bumps or was making turns. From the other things like hearing it at freeway speeds, this may not be the problem, but it does not hurt to check.

Hinckley,
I just had to have my hubs replaced because of that vibration. When you said it was like driving over grooved concrete I knew what you meant. Or maybe like driving on a tire with a broken belt or severely out of balance. It's actually the bearings but you can't just change the bearings, they don't sell them so you have to replace the whole hub, $400 + a piece. The cheater way is to remove the old ones (?) and look at the part number then get the new ones pressed in. I personally had the hubs changed.
