Annoying popping sound under floor.....FIXED!

[Caloosahatchee]

Well, this seems to be a common problem on Excursions. I started to get an annoying creaking/popping coming from under the passenger's side footwell of the X. After doing some research I went ahead and ordered the sway bar bushings awhile back. Anyway, on install day, I took the sway bar off and drove it.... still there. So I tossed the bushings on regardless since its one less thing to worry about down the line.

Well, back to the drawing board. I had the suspension checked out at my buddy"s shop and while he was there he tightened all the spring shackle bolts. Now I knew the suspension mounting was tight but....noise still there.

Finally, I read about the body mounts sagging and causing noises so I investigated this possibility. I removed the bolt and pulled off the bottom of the mount. Then I cleaned the sleeves, shaved some off the upper sleeve, and lubed it all up. Noise went away for a couple of weeks, then started back up. So I got under there the other day and sprayed it down good with PB Blaster. OMG, it got 10 times worse! So I went to the hardware store and bought a few 1 inch washers and opened them up a bit so I could tap them on over the upper sleeve, I used 2. Reassembled everything and PRESTO, the noise is finally completely gone.

Just thought I would share this since it seems common.

I have poly mounts on order and am going to have the body lifted and all mounts replaced, but at least I don't have to hear it for the next 2 weeks!

I think I've heard this on the f series.

My Samsung SGH-I997 made me send this.

My popping noise is getting worse on my truck, and other than replacing the springs, my front suspension is fairly new. Where did you get your poly body bushings?

I was wondering if it was swaybar bushings or body mount bushings. thanks for the info - I know what I'll be doing soon

I bought the Daystar kit from XDP, they haave a really good price on the kit, from what I was able to find. Its not Excursion specific, but its for 99-07 Superdutys. I think I may have a 2 extra mounts on the Ex, I was unable to verify this. However, if I replace 8 of 10, I will be happy....esp those two under the front footwells.

7.3P, I will warn, if you try what I did that mount won't go back together nice and pretty like it was. The washers will not slide all the way down flush with the flange because the upper portion of the mount sticks out slightly. The washer will lie on that piece. Then I torqued it until I basically collapsed the lower portion onto the washer. Its not a "solid" mount, per se, but if I wasn't replacing them within a year or so (for example) I don't know if I would have gone that route. Although I have read about people removing the bottom piece entirely and using a solid mounting method so

How about doing a body lift? Would that take care of it like replacing the body mounts? How much was the kit u bought? I mean if I can get a body loft for around the same price as replacing the body mounts, I may go that route. I have seen a psd with a 3" bl and nothing on the intercooler piping was needed to be modified.

I was wondering what that sound was. I might have to. Look in to this.

Good question. That seems like it'd be a win win situation
