Not in my experience. Bushings were making noise after a while because the grease would slowly disappear somehow. This was just an easy way to refresh. Checking brakes between track days is just a convenient time to do it & prevent the noise from ever happening. Reinstalling a sway bar every few months seemed like a ridiculous waste of time to me. Spray force is like WD40 so it's not going to push anything out. Plus this is the same lubricant that came with the sway bar just in spray form so they play nice together.
The OEM rubber bushings do not need to be greased. Aftermarket sway bars that use polyurethane bushings like this one come with a silicone based lube with instructions on how to use it. If you don't lubricate polyurethane bushings they're going to squeak like crazy & slowly get damaged over time. The sway bar has to move around a little in bushing for it to work. ua-cam.com/video/3O9rK8tKCTI/v-deo.html
The purpose of those bushings is to keep the sway bar anchored onto the frame. It doesn't defeat the purpose of the bushing at all if the sway bar rotates independently of the bushing.
From my understanding the movement of the bar separate from the bushing is necessary because the opposing forces on the bar need to be able to transfer energy from one side to the other. Hence a torsional spring.
Bare minimum I would do is loosen bolts then push in silicone grease in to either end, the re torque bolts back up
Wouldn’t spraying to the bushings push out all the remaining grease and cause more noise?

Not suppose to grease those... they don't need to slide back and forth... defeats the purpose... seriously Mr. shadyside of the tree
