Excessive negative camber on my rear wheels

PCalc is a cool cellphone calculator app, has the trigonometry functions (including arctan). It displays like a basic calculator in portrait orientation, adds all the trig functions in landscape. Also has RPN (Reverse Polish Notation), which is irresistible once you pick it up, allows you to eschew bracket nonsense.

In the landscape, attached image, “tan-1” represents arctan.

might just be iPhone though.

 

Have more extreme negative camber (over -11.5°) on the drivers side rear wheel of my 2010 Prius. After hitting a very nasty pot hole about 2 weeks ago, I noticed what seemed like a bit more negative camber than usual, maybe 2-3 degrees a couple days after the pot hole incident. I was very busy with 2 pressing projects at the time, so I didn't pay a lot of attention right away. Now it's more than a week later and the camber has increased to the point where there is a 5" offset from vertical between the top and bottom of the tire. Did the math and it works out to over 11.7°. The tire is rubbing on the strut so I'll have to have to have the car towed to a repair shop.

 

New rear axle in your future? Lots of road salt, suspension rusting out?

 

I'm seeing the same issue on My 2005. I found a NOS one near me. Going to replace the hubs as well. Mine has no rust issues, just 190K worth of poorly maintained NY roads pounding it over the past 20 years.
