Banging Noise from Front of F-550 chassis ?

[Catoff]

Hi. My father-inlaws tripple e commander 2002,only 12,000klms. Has been in storage many years and i have the job of bringing this RV back to life :). I am hearing a loud banging noise when im driving slow? I have greased all points of the chassis i can see. Swaybar links,bushes look intact and check for broken bolts,i removed the lower bolts from the Bilstein shocks and they extended normaly without delay or noise,Checked front wheels bearings for play.
If i jack up either side of the front of the vehicle and then release the jack quickly i hear this noise the same as when driving slowly.

Has anyone heard of or had a similar issue like this ?.

Not many things would be common to both sides except the sway bar.

My brother in law just told me his "noise" story and it turned out to be the wheel simulators. He pulled them off and found something that was loose and making noises...

Sway bar bushings may be bad. These are the rubber bushings that are in the middle of the sway bar, where it attaches to the frame. There should be two of them.
The bushings can be bad at the end of the sway bar also, at the links, but I think you said you checked those.
