Alright, symptoms are a very loud banging - like a 10 lb. sledge hammer on the axle, springs or frame when hit a bridge joint, tar joint in road, slight flexing up and down from a very very shallow dip. It is very loud, and a very solid sound. Does not effect steering. It is the front right wheel. I spent about 1/2 hour under the front to see was there a spring bolt loose, had a shock came loose, was there any loose bolts on the hub or wheel attachment.
Two months ago, I took it into local WH authorized shop. They spent 3 hours and $285 later to tell me one of the 1/8" X 1" brace that goes from the front frame to the bottom front fender opening was loose on the front frame, and that is what I heard banging. They tightened it up, and said they fixed the problem.
OK, don't believe it, but drove the MH 6 trips 30 to 120 miles, and no noise at all. But last time we were out, 60 mile drive, 2/3 the way into the trip on an interstate off ramp it starts again. Every single crack in the pavement, be it concrete or asphalt, very very loud noise. I immediately stopped and again got under front end, and can't find anything. Called to find a WH authorized shop (MH is NOT under warranty), and was going to say, forget the camping, take it directly to WH. No, I'm only a few miles from camping, I'll go there and then go to WH garage.
Leveled the MH, which took the front wheels up, almost off the ground. "Broke camp" early to head out to WH and no noise. Wait a minute. I took a short cut across a rough state road, and still no noise. 60 mile drive home and no noise at all.
I'm really concerned a wheel is going to fall off or something. I really would like educated guesses, as I'm going to take it back to WH and show them the frender brace is good and tight, and there is a loud noise.
Please I'd like your feedback.
It is an early '04 W22 chassis.
