2017 Toyota prius sounds like a wobble behind it.

Given the mileage and symptoms, a worn shock absorber is a top suspect. Have this checked first. A "wobble" often points to a worn damper (shock absorber) that is no longer controlling the spring's movement properly, leading to an oscillating or bouncing sensation. If shocks are leaking or bushings are cracked, replacement is necessary.

 

tyre?

 

I'm not sure what a "wobble sound" sounds like and I don't know what "resources in the suspension system" means? We can all guess at what your trying to allude to. There's plenty of parts to pick from in your rear suspension system - but you'll need to be a bit more specific in your problem description.
You should probably take it to a professional because it seems that your a bit out of your depth here.

Was this an AI generated problem description???????

 

my guess: resources = rust sources?

 

This bolt in particular (from second of OP’s pictures) is evidently adjustable:



That said, barring a curb bump or similar, I don’t think they just slip out of optimum alignment, more likely something rubber, bushing or tire as mentioned.
