I recently purchased a 70-200mm F2.8L USM lens and when I hold the shutter button half way, the lens is just focusing back and forth, and not finding anything to focus on. If it does focus on an image,80% of the time the image is out of focus. I’ve tried it on a T5 and an 80D but the problem still exists. Manual focus works great and the pictures look good but the AF is basically focus hunting.I’ve attached videos/pics in the links. Could also be user error 🤦♂️. Thanks I’m advance for your help.

Looks like your lens is severely damaged.

Yes, I know that the collar is missing. The seller had mentioned that it was missing but didn’t mention that the first group lens was missing so I had to purchase/install one since canon can’t service the lens.

I suspect you have a Canon EF desk ornament/paperweight. Can't even call it an EF-L paperweight since it doesn't have the red L ring.
It also looks like the area behind the element is damaged.

Unfortunately replacing parts is only part of the work required to repair an AF lens.

Sorry sir, but you bought a lemon. The "bargain" is no longer a good deal. "Seller didn’t mention that the first group lens was missing" Red Flag.
You can try sending it to MidWest Camera dot com and hope it's not a money pit.
