Or ice pucks. The poor mans body lift from the 80-90's.

 

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?

 

It's more of a creaking noise, if it's the body mount.

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.

 

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!

 

From your description, it sure sounds like the body mount.

 

...or the bumper has been removed/replaced or the PO slid into a snow bank and that pushed it up or...or...or...

 

Check the splines on your drive shaft too. When you start/stop, the axle moves ever so much from the torque, and that has the drive shaft change length just a little. There is a boot in the middle where the splines are. I had a clunk when stopping and when starting and sometimes when letting off or on the gas at low speed.

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

 

Sounds like sway bar bushings.

 

Had anyone ever tried putting some glue on some doorstops and beating them in between the frame and body?

 

Thanks! Does anybody recomend the stock rubber ones or the polyuerythane for replacements?

 

Daystar KF04050BK Body Mount

Will this at least address part of the problem?

 

I just sold the 02' had over 50k on new oem mount with oem shim and no noises...

 

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.

 

Ford had same resolution, with a plastic shim.

 

Bought 4 "kits" to replace the 2 under my feet and the 2 behind it. Lasted a year and started creaking again. I love the truck, but the creaking is making me hate it. I had the "grind down" done, but that only made it worse. I feel like there is ultimately no cure. Just venting.
