Loud squeaking over driver area, mainly in city when swaying side to side. Tried silicon spray over cab on outside, no help. Have overhead bunk. 2018 chatuea 28z.
Our WS31 drives me nutz! Sounds like a styro-foam ice chest riding in the back seat of the car! High pitched squeak, squeak... squeak! Usually at highway speeds and different road surfaces also. Concrete with joints is the worst! I don't know where it is coming from!

Ouch...
It's time to get another pair of ears on board, and try to figure out where the squeaks are coming from...
Get someone to ride along, who isn't afraid of moving around a bit inside a moving coach. Take the rig someplace where you can get it "rockin' & rollin' a bit...
Let them use their ears to find the source.
Once you've got that figured out: it's a matter of figuring out what will do the job. (And that will depend upon what the source is!)
Good luck!

Look at the front springs where the front half mounts to the spring hanger, if rusted the squeaks are probably when your driving the leaf's are rubbing together, check u bolts and hanger bolts and use some chassis grease on them same applies to coil springs they sit on a urethan base and no one ever greases them.

So I tore apart the overhead cab area since not covered by extended warranty. Took several hours, found the squeaks coming from loose and broken screws that hold the cab to the Thor overhead bunk. Replaced broken screws and added a dozen more between them and also added caulking between the steel cab frame and the outside cab. squeaking comes from the Styrofoam rubbing against the loose screws and loose cab overhead structure. Several hours work but squeaking is gone! Saved $600 by doing it myself, old handyman guy.

Squeaks and Noises can drive you crazy. I had what I tought was a wind noise coming from the drivers window. Turned out to be the sliding glass on the pass side was not closed all the way.
Still have issues with a few squeaks still, but warranty is handling that slowly.
Did the soundproofing under seats and Doghouse, and finding more squeaks, LOL...
I have squeaks as well in our 2017 ACE 30.2 Driver side only. Sounds more like wood squeaks. Started a few months ago going around corners and rough roads.
