F53 front end shimmy

It is for sure in the steering. Not an engine miss

"Shimmy" usually makes reference to a front end/tire problem. Could it be that you are chasing a "vibration" from another source, like engine misfire or drive train?

Shimmy is still there. Not all the time, but very noticeable.
6 brand new tires and balance, no runout issues, toe is set to 1/8" in.
Put 400 miles on it today. No tire wear or issues, but still have the shake.

This is a 2008 Damon Daybreak F53 chassis.

Any ideas?

I had something similar. Although the vibration wasn't bad. I could feel it on the steering wheel. It didn't pull toward any direction. I had them check the drive shaft and all the possible wheel problems. No answers. I asked on the boards and still no fix.
Then one day I was talking with and old time mechanic and he asked if it did it more when I was going slightly up hill and the engine was working harder. I told him yes. He said it sounds like your missing a plug. Sure enough, a bad spark plug. Fixed it and problem solved.

Start by checking tires for RUN-OUT. Any tire dealer can do this in a matter of minutes.

Sorry, 2008 F53.
No bent wheels, brand new (This week) tires and balance. Nothing bent or damaged.
No tag axle.
Just noticed the shimmy earlier this year. Happens around 45 MPH.

There was no 1998 F53 chassis. Is your coach on a 1997 or a 1999 chassis. If a 97 chassis with 16" tires, have the damper on the tie rod replaced.

If it ever hit a curb or pothole, it could possible have a bent front wheel.

Possibly some of the rubber front end bushings are worn out or rotted, or have been aten on by a rat?

Maybe the steering stabilizer shock is worn out or leaking?

A tire could be out of balance?

Does it have a tag axle?
