96 Lincoln continental. suspension problems????

A lot of noise when turning left or right, two pieces hanging from the assembly near the tire. Not sure if it's cv joint issue or ball and pinion

Pretty sure that it is a stabilizer bar link. Easy to replace and not expensive.

Air suspension in front since I bought it 3 months ago it was working fine but about two weeks ago stopped working and the front end was down so far it was hitting bottom. Last Thursday it looked like the front end was up again so I drove it around fine until I went grocery shopping and after we emptied the car
the front end wouldn't come back up. Is there a place to add air to the air suspension unit for the front end in my 1996 Lincoln Continental, thank you
