Jack the car up so the wheel is off the ground.

Put a second jack under the air spring and jack it up a bit to take the pre load off the rear suspension.

You'd be surprised at what you'll find, it's not always the mileage that makes these suspension parts wear it's also the AGE of the parts, I have 72k and redid the whole front end last year, going to tackle the rear slowly this year.

If you note my post above there is at least one piece on my rear right that is worn bc my tech couldn't get my side closer than -2.9 degrees
