Truck makes a knocking noise and feels like its drifting

HI.
I have been having an issue with my tacoma prerunner. It involves a knocking when backing up and turning. I have taken it to several shops, including toyota, and every one keeps saying they don't know, or what it "could be," however, I have a video (Diagnosis?) of the underside which shows damage to parts, (that I don't know of) and I'm trying to figure out what these parts are, and if they could be contributing to the knocking/clanging.

I have already replaced the driver side sway bar links (so to see it torn again in a matter of months is odd) however there was no mention of it or the other things he pointed at, in the report at all, it just said I needed my windshield wipers replaced, which clearly is not the main issue here.

Any Help would be greatly appreciated.

 

Can you take a video of the truck backing/turning with the sound?

And i'm assuming by drifting you mean it's pulling to one side, not drifting like the below?

 

Yes. It feels like it's pulling to the left side.

 

How long has it been pulling to left? If at least a few thousand miles, it should be evident in the tire tread.

But typically a pull will be an alignment issue. Either a suspension component like ball joints has more play in it than it should, or something like a pothole changed/bent something

 

it's been pulling for about a week now.
Thanks for recommendations also
