Probably a control arm bushing, possibly a strut mount or stabilizer bar bushing. Mine was the control arm bushing, 2001 Windstar Sport pkg.
The stabilizer bar rotates on the stabilizer bushings (usually 2 bushings required) be it front or rear of vehicle.
its a bar that gose over the suspention and keeps the rear wheels ballenced with each other and the fornt wheels too. i broke my front stabilizer bar jumping and i cost my like 145 to replace it.
The bar is called the stabilizer bar and the small rod at each end are called stabilizer bar links. The stabilizer bar links attached the stabilizer bar to the lower control arms. This assembly reduces vehicle roll during cornering. This is good information for you, call Strutmasters they can help you with any of your suspension needs on this vehicle.
Sway Bar
sorry to hear your problem .. i had similar problems .. try changing your front stabilizer's bush or change the whole bar ..
Generally the stabilizer bar end links break before the bar does but the bar can break. You will have to physically inspect the system to find out why it is loose. Worn/damaged stabilizer bar bushings could also be the cause.
Never saw a shock on a sway bar. A shock mounted to the steering linkage would be a steering stabilizer.
Have the tie rods, and trac bar checked for play.
You didn't mention front or rear, the rear is much easier, the front one is one pain.
Which would be evidence of price discrimination at a local bar called the Stabilizer
It's intended to prevent excessive leaning when you go around corners. When one front wheel starts to get the extra weight of going around the corner, the sway bar/stabilizer transfers some of the weight to the opposite side spring.
