Next question,where is the coach,maybe one of us is near to check it out?

John the Coach is in Sacramento California.
I am looking to buy it.
the coach has been idle for the last 3 years .
I own a Country coach and mine does not make that kind of noise when driving low speed trough the neighborhood.

There is a lot of open space between the bathroom floor and the underside of the coach. Might be worthwhile looking in the storage bays to see if there is anything loose that is banging around.

The noise reminds me of what it used to sound like back in the day when your car had a broken tail pipe or muffler hanger.

Brett is correct in my opinion. It not the third member and doesn't sound like a u-joint or bearing. Sounds like a shock mount or a suspension bushing to me. Best to get a good mechanic to look it over before you purchase. May not be a costly repair but best to know before it's yours.

Is it possible that the air pressure is not correct for the tag axle air bags? Pretty sure they require air pressure to keep them pushed down. When you raise the tag, push the "raise tag" switch on the console where the retarder lever is. See if they raise up, then push switch again to see if they lower.

I would ask the owner to ID the problem, then either fix it ,or reduce the sales price.
The coach will be hard to sell for top dollar with that Unidentifiable noise.

Had the seem problem a few years back. After a misdiagnosed expensive repair while 2000 miles away from home, Keith R at MOT discovered it was a combination of a bad shock on the tag and worn brake caliper pin. Sound was nearly identical as yours.

I actually raised the tag and left it raised to see if that noise would change when driving.
the problem is that everytime you get past 10mo per hours the tag drops down by itself.
it did it at every stop.
I would her it dump air on and off when stopping.

5MPR is the safety limit when driving with the tag raised

Yes it goes into Travel mode.
when the engine is on also Auto Levels.
I can also raise the coach(that's how my mechanic noticed that the Tag Air bags were deteriorating)

Travel mode only indicates 80+ lbs of air. It could still not be at ride height. However, I think you would notice it on the wheel wells first.

+1

One should visually verify that the coach is at ride height on all 4 corners.

I have not watched video but pretty certain it will be a slightly loose upper shock absorber mounting bolt, that is why it resomates thru the frame. The lower ones would not transmit the same.
Put a socket on it to test.

We have an inexpensive wired camera that we have used to find things under the coach while driving. Temp mount with wire ties and learn what moves around.

Update I took the coach to a local shop and they took off one of the torsion arms and the rubber is shot.
ordered new bushings they will have them here in few days and hopefully that this will improve the noise.
the mechanic said that the lower axel mount was also touching metal on metal I will post more pictures as we go trough it.
