Loud front bang !
I have a 2002 Fleetwood on a W22 chassis. In the past few weeks while driving down the road and hitting a few bumps or dips, I get a loud snap on the passenger side. My wife says it feels like it is coming through the floor boards. My mechanic and I have checked the shocks, springs, etc: without finding anything. Could it possibly be in the bushings in the square torsion bar? If so where can I get new bushings?

It sort of sounds like the elastomeric snubber (that yellow thing on each side) is hitting and bottoming out. It may be that the shocks are worn and letting it hit too hard.
Mine did that on the drivers side until I got new shocks.
By the way if you still have the 2 inch stabilizer (torsion) bar I would replace it with the 2 1/2 inch bar WH started using in Sep of 03. It makes a great difference in roll and sway. That will also give you new bushings.
I did the job myself (easy to do) and I think the total cost including renting a 500 foot pound torque wrench for a day was about $150.
This is an email I got from Workhorse:
"The installation is very straightforward. Remove 4 retaining nuts while supporting bar, remove bar, hold new bar in position, reinstall 4 retaining nuts, and torque to specification (275 foot pounds). This procedure is NOT meant to replace the service manual, but is a generalized procedure.
The upgraded stabilizer bar has been shown to provide the following benefits:
1. Reduced Body Roll when cornering.
2. Reduced "rocking" when passed by or passing large vehicles.
3. Reduced "rocking" when traversing bumps on an angle."

Your noise sure sounds like the one I had several years ago on my W22.
There is a kit available from Workhorse for missing teflon type spacer bushings on the spring hangers. The kit number is 2943. Do a simple search in the search box at the top of this forum, for more information. Just put in "front spring pop".

A slight chance it could be a heat shield flexing.

I had a similar noise coming from just below the back of the passenger seat. Took some searching, it turned out to be a part of the flat steel cross joist supporting the floor had a crack in the bottom, where the flat joist was punched out probally to provide the passing of wiring etc. Just remove your engine cover and with a flash light, look down and behind towards the rear of the coach, that flat steel crossmember joist is about a foot back, mine was cracked/broken open at the bottom edge. A little bit of JB Weld and voila, fixed, noise gone.
Hope this is helpful. Edouard.

The sound is just like what I was hearing on the passenger side and my wife described it the same as yours. I really only heard it at slow speeds on uneven surfaces. Mine turned out to be a broken weld that attached the front cap to the frame and a broken weld that attached the box to the frame. Both could be viewed from the front wheel well, forward and aft of the tire. After having them welded, no noise....knock on wood. Here is one photo and I can probably find a pic of the second area too. http://www.irv2.com/forums/f22/front...se-105770.html

I had that problem when the rubber bushing on one end of the stabilizer or torsion bar cam out for some reason. That allowed the bar to hit the frame or hanger. It really sounded like fast taps on the metal frame with a hammer.

I've seen broken stabilizer bars too and they make noise. The weld split and the 2 ends worked against one another.

"Loud Front End Bang"
Thanks to all the responses to my problem with my 2002 Southwind Motorhome. We found the problem! It was a 1-1/2" square tube that is part of the support for the passenger side of the house and framework for radiator and etc: It was broke completely in half. All welded and we are back on the road.

Yes indeed, Thanks for the update. We have seen broken framing members here before but those are very rare.
