Swaying bus

Check the radius bar bushing 's . ALL radius bar suspension's work the same way. Mis- installation can and normally will cause proposing  or wallowing...rdw

Did you replace the front sway bar bushings?

Don -

No front sway bar on a 4106, only a rear.  But a front bar off a 4905 will fit on an '06 with a little bracket fabrication.

What air pressure are you running in your tires?  Excess pressure can sometimes cause unusual behaviors.  Run your coach across a CAT scale in "ready to roll" condition (full tanks, groceries, clothes, etc.) to find out how much weight is being carried on each axle, then go to your tire manufacturer's website and find the inflation tables for the tire size on your coach.  On my coach, once weighed, I dropped the air pressure 15 psi/tire and the ride and handling changed quite a bit.  Much nicer ride being the major difference.

Totally agree with Dan about the front wheel caster and alignment settings.  Radial tires also require 0^o to 1/8^o toe-in per most manufacturers. . .

Finally, a "rock 'n roll" side-to-side ride is not uncommon in air suspended coaches, especially the earlier models where the air bellows are mounted inside the tires (like your 4106), as opposed to today's models, where the bellows are just behind the coach's outer skin.  Eagles, with their Torsilastic suspension, tend to "porpoise" with a gentle front-to-back motion, which can get really bad if the front shocks are shot.

FWIW & HTH. . .

I had the same rocking side to side motion on my 4106 when I purchased it.  The two rear height control valve links were egged out, causing it to flop to one side while the other side's air bag deflated, then it would flop to the deflated side..... over and over.

New delayed action valves and links solved the problem.

Also, ditto on positive caster.  4106 needs lot's of it especially if it has power steering.  The specs in the manual are for manual steering, not full power steering.

I talked with Luke he advised lowering coach position some , It helped tremendously ... I still have a lil but not nearly as bad . I will check back air valves and hardware also . Thanx for all the advice!

Dumb question... Is all the info you are giving for a 06 basically the same for an 07?  I have a 4107 and I'm just wondering.
Thanks
