On my 1998 ford windstar there is banging noise from the front passenger wheel. Happens when you have the van on the ground and the wheels straight. When you move the slightly move the steering wheel to the right and then back to left. I have just replaced the lower control arm which included a new ball joint. Had to replace old one, the center rubber bushing was bad. I also replace the wheel bearing 2 years ago, could this be bad again? When you jack the van up the tire will not wiggle like it did when I had to replace the bearing.

If I understand correctly, the noise occurs with the vehicle's weight on the wheel, and you're turning the steering wheel. That can apply to an inner or outer tie rod end, but with the strut suspension system, it's more likely you have a binding upper strut mount. That's not a serious safety issue but if it gets bad enough it will lead to "memory steer" where you have to tug the steering wheel back to center after going around a corner. That can be miserable and tiring to drive.

To identify a binding upper mount, reach over the tire and wrap your fingertips around one of the coils on the spring, then have a helper slowly turn the steering wheel partway each way. The spring should rotate smoothly with the strut and wheel. If the mount is binding, you'll feel the spring wind up and build tension, then suddenly pop free and rotate.
