Rear axle moves back & forth

Yahoo Message Number: 108505
My 2007 Inspire under hard acceleration from a stop will cause the rear axle to move out of alignment. The same thing can also happen under hard braking. The result is the coach will "dog track" until it rights itself again. Does anyone know what is broken or loose that is causing this problem? Wayne

I went to Junction City last spring. I had several things on my coach that needed Kevin Waite's attention. His chassis inspector Bryan found 2 loose nuts and 2 nut completely missing on the drive axle suspension. I had 47,000 miles on this coach. I believe Bryan saved me from a possible disaster. I would get that looked at by a competent Rv mechanic or truck shop ASAP.

Get it into a competent chassis shop, inspected, and fixed. This could be a real safety problem not just for you, but those around you on the roads too.

Not trying to preach at you, but could be a real dangerous. (Or maybe not - but until the problem is determined, you will not know.)

Best of luck to you. And please, report back what you find out, as it could help others down the road:)!

Wayne,

Look under the coach on the passenger side and just ahead of the outside of the tire. You'll see a very large bracket that is bolted to the frame at the top and has a large bolt at the bottom. You can see this without climbing underneath the coach. Look on the large bolt at the bottom and there will be a large washer under it (Everything is large under there). There is another washer on the inside. These washers must have some tack welds to the beam that runs front to rear and underneath the differential. I suspect the welds have failed or were removed by someone. This is where the adjustment for the thrust angle is located. Sounds a little Mickey Mouse I know but knowing that many large Class A's have no adjustment at all this is not too bad.

If this is your problem you will need to get it to someone that has the equipment to adjust the trust angle then place a couple of small welds between the washers and beam. Just tightening the large bolt will not hold the thrust adjustment by itself.

If pictures would help let me know.
