For those of us plagued by a monkey banging under the floorboard, I offer this as a possible solution in as much as, for now, it works. The left driver side floor board mount develpoed the klunks like everyone else has experienced. After trying all suggestions, I took it to the dealer---twice. Today, it started again  The idea someone mentioned about the bolt possibly hitting the body housing came to mind. As I recall, someone tried grinding a place on the frame or body. I thought perhaps I could insulate the bolt as it goes through the body and the upper mount (technically it's called an "insulator" for yhos who care). I finally saw a possible answer sitting in the garage after a box of "stuff" fell off a shelf. There before me--Golf club grips! Yes--I'm not crazy--Rubber golf club grips. I played around with sizing but basically I cut the grip right below the top (butt end) and started fitting it as a sheath over the bolt. I finally settled on a length that was approximately the length from the top of body bolt hole down to the top of the lower insulator. There are no threads at all in the upper insulator. Once I could fit it where it would go down and engage the first part of the threaads, I trimmed a bit more and started tightening. I torqued it to 65 ft-lbs (not 105 as when I got pissed and decided to tighten the hell out of it) I took it out and put it into hard circle turns---No More Noise! Again, who knows if the demon as been tamed but at least I have a reprive! Good luck!

David,
Is this the same issue that causes the "creak" every time the weight shifts? I can literally sit at a stop light the gas it just a tad and hear the creak. When I apply the brakes it does it again. Turning into my driveway (small bump) the frame twists and I hear it again. Drives me crazy! Feels like a popcorn machine under my left foot! |

Okay guys, I have listened to this noise as well and it is getting old. A mechanic friend of mine fixed it temporarily by lifting the body off of the frame a tad and lubricating the body mount bushings. This worked for a few weeks but the noise is back! Will replacing the body mount bushings fix the problem? Should I use the factory bushings or polyurethene? Do I need to make good use of an old set of golf clubs or is this just a fluke?
Thanks,
Roger |

I had the noise, I pulled the carpet, used an electric impact wrench with a U-joint, pulled the bolts, both sides, wire brushed them, made a heavy rubber washer, installed that under the flat washer on the bolt, so that the washer makes contact with the floor board, re-installed the assembly, presto, the noise is and has been gone for a month or two.
I wonder how many Ex'es have been traded in because of this annoying noise...
It's about a three beer job, do it and relax.
Take care, Oz. |

Yeah Matt--what you describe is the dreaded clunk! After a few days of my bolt condom, the clunk came back. Not to outdone, I went after the last area I had not touched, the area between the lower insulator and the body mount. I cut a plastic washer aout of a heavy thickbess bucket (cut a lit in it so you can get around the connector housing and bolt)so I could loosen the body mount and slip it between the top of the connector and the body. I also made a rubber washer out of a medium thickness rubber door jam--like you use going from carpet to tile, etc. (I know they wonder what the hell I'm doing in Home Depot strolling around forever looking for something I can modify.) After this, the noise is gone and has stayed gone. After this, my guess is that after time the opening in the mounting strut from the body gets slightly "wallowed out". There is a Hex interlock between the upper and lower insulator but it has a good bit of play. I'm guessing after having 7700 lbs torquing it, you get some play between the two insulators that you can't fully torque out with the standard set up. Another fella also put a plastic washer between the upper mount and the body. The dealer tried 3X to fix this and could not. I don't think there is such a thing as over kill on this monster. Maybe we make more right turns , or there is more weight on that area or maybe it's the angle of the mount--all guesses. ANyway this works! I have been amazed how much quiter the whole X is with this *&^%^%$*^%$^%(* noise gone.  |

Oh I used the same thing Ozzie did with the rubber washer under the flat washer next to the floor board at the same time I did all this other stuff. Like I said, I don't think the word "overkill" applys to this  thing! |

New installment--same aggravation with body mount noise. The lower mount has been replaced 3X...last time being by dealer today. They did a test drive after changing transmission fluid--and it is still there. Hell I pulled the lower mount this past weekend, took the bolt out and it made the SAME noise--all of which suggests the lower bushing and/or bolt are not responsible in my case. The dealer sent in over to the body shop so we'll see what happens. I let you guys know if they find the "magic bullet".  |

David,
I have a 2000 Limited V10 and I have the same problem. The sqeaking is driving me crazy! I haven't had the body mount bushings replaced yet because I am afraid that it won't fix the problem. We put man on the moon 36 years ago but there isn't a concrete solution to this problem it seems.
Let us know what you find.
Thanks,
Roger |

Glory Halleluiah Praise da L  awd!!!!!!!!!!!!!!!!
Gentleman--the clunk f romHELL is now gone!! If you will note that my last post on this edition of body mount torture started two weeks ago. Tomorrow I finally get the X back. After screwing around and revisiting all the stuff I had done--even THOUGH I TOLD THEM AND even THOUGH I told them to take off the lower mount and the bolt--it would still make the same noise-----FINALLY they replaced the upper mount. Before I took it in, this is what I observed. It appeared the upper mount had partially collapsed-as it was smaller in height compared to the right side. There is a metal sleeve in the upper mount that the lower mount locks into. It appeared that the mount had collapsed enough to force the metal sleeve beyond the end of the mount and thus it had a piece of metal scraping back and forth in the frame bracket. No matter how tight you made it. it could not stop because the upper mount had lost some of it's rigidity and loading it would torgue the internal metal fitting so it would scrape against the frame. I am TOO tired to tell em "I told you so!" Just glad it's over!  
Any who dare tread in my footsteps--may God have mercy on your souls!  |

Hello first post new to these forums as i just bought my 2000 excursion last friday. Ive been a ford tech working in a dealership for ten years now and thought i might throw some knowledge out there on theese noises. Typically the pop under your feet during body flex was the cab mount bolt(under your feet) contacting the body on the nonthreaded portion of the bolt just under the washer. What we would do to fix is remove the bolt take it to a grinder and grind away on that nonthreaded portion of the bolt about till the washer ould come off. then with a die grinder and tapered stone bit hog the hole in the body out a bit sot there is now space between the bolt and the body. Then finally we put anti-sieze on the bolt nonthreaded portion just in case then slap it back in. I probably did this to atleast 200 pickups and excursions as it was a common problem on the first few years of these vehicles. As for a squeek noise the front leaf springs have plastic bushings on both ends between the leafs that wear out and then are very noisy on umps. Ford has a revised kit that replaced the existing bushings and adds a second thicker stacked bushing on top to extend the life of the bushings. Hope this helps someone!
