I've had it with these Body Mounts!!
#32
Ok, I have read these posts about grinding the post and/or bushing changes. I have performed the grind fix with no good results. When I am driving over turbulent road I get a rapid clunk - clunking, not a squeak. The sound is comming from under my feet. Has anyone had good results with changing the whole $100 body mount assembly? Could it be they front sway bushings?

Also, I had no luck with the grinding method.
I replaced both upper and lower body mount rubber new bolt and new shim, torque to 87lbs. And NO Grease. This took care of my noise.
Don't know were your noise is comming from. But the usual body mount that fails first the noise would be down by your feet when driving.

Any update on the clicking/clunking noise if was the body bushing?
Did you ever figure out if it was the Body mount bushing? I am now having a "clicking" noise on take off and when almost at a complete stop (about 2-5 mph). I can reproduce this sound when stopping and in the first second of take off in reverse. Stop again and move vehicle forward a foot and a "click" when breaking again. I have replaced virtually the entire front end (upper/lower control arms/breaks/callipers/balljoints/bearings/sway bar bushings) and when I have my hand on the body bushings I "think" I can feel the clicking there. Just checking if your clicking/clunking was the bushing? Thanks!
I keep hearing the sound described as a sqeak but I get this deep, clunk sound... like something in the suspension loading up and then releasing. I've had the front end checked over numerous times to try and identify it but everything is tight. Could think occasional clunking sound be the mounts? Does anyone else have this deep rubbing/clunking?

Pulled the drive shaft down, lubed the splines, never heard the problem again.

Don't know if this would help since I haven't delved into the body mounts on an Excursion, but I used to have a Chevy Avalanche and Chevrolet had actually issued a TSB on body mount noise. Their solution was a really thin (couple sheets of paper thin) plastic washer (the washer was really thin so it was quite flexible). They were about 2" in diameter and just slipped in between the frame and the body. Super simple solution and they worked on the Avalanche. You might even be able to get them from Chevrolet and use them on the X.
