national surfside shudder

[5421utopia]

Need help with my 2006 surfside 29A. I am having a problem with a shudder in the front end . it does not happen all the time. it feels like I am driving on a egg shell. It will vibrate to the point that I feel that I will lose control. New tires where installed when I purchased the unite 2 years ago. There is a total of 21,000 miles. I have it at the ford dealer now and they can not find a problem. It is on a ford 550 chasie. has anyone had the same problem?

Depending on exactly when the chassis was built (you are at the juncture between older F53 and current generation F53), you could have the older chassis with NO track bar/panhard rod in front or the new one with the bar.

Look under the coach for a bar going from the front axle on one side to chassis on the other. If not there, buy one.

Is there any odd pattern to the tread wear? A broken belt or tread separation will cause those symptoms.
