Coil spring boosters are only for coil springs, NOT those found on struts. Struts are engineered to function in only their original configuration and should not be modified. Look into finding new struts that will fit your application.
Cars would use shocks or struts in front but not both.
on a vacuum type booster there is usually a vacuum leak. either on the rubber line that runs from the booster to the engine, or a hole in the diaphragm inside the booster. the rubber line is easy and inexpensive to replace so i would check it first. if you have a hole in the diaphragm the only way to fix it is to replace the booster.
The power booster check valve would be located where the vacuum hose is connected to the booster. The vacuum hose is connected to the valve and the valve is inserted into the booster. They are usually made of plastic.
That would be the power brake vacuum operated booster.
bad mastercylinder.
You will need a spring compressor for any strut installation job.
One possible answer: Loose bolts in combination with bad shocks or struts.
I would say a power brake booster or a brake booster would be the same.
Normally, you would get a booster shot in your arm.

Yes.
I would presume the young of an Impala would be a fawn, like the common deer
If struts are included, I would guess $200-400.
I had the same problem with my 92 voyager when I bought it. For me it turned out to be the upper spring plates on the front struts. Had them replaced and it's been quiet ever since. NOTE: You might have to do an alignment if this is you situation as well.
Power booster failure or vacuum supply to booster failure.

i would say that an impala is similar to an antelope. Also, it could be a Gazelle
