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