your bump stops look to be in bad condition or non existent . your shocks need replacing (if you look at the top end at the rubber bush they are wet) and your exhaust manifolds are missing shields which usually coincide with you might have cracks or missing exhaust bolts. ask me how i know lol. also check your stabilizer bushings and link bushings

 

Adding to that already said, some of your zerks need grease.

GM considers shock wetting like this normal. Ask me how I know….
Just do a bounce test. I bet they may be ok.
There is a split plastic boot on one shock. Not critical for function.
It keeps splatter and dirt off the piston rods for longer life
If it was me, I would change them. But I am a perfectionist.

Tire rub on front sway bar is normal. OEM tire do not clear it on full lock.
