Front Bearings, w210

[notfarnow]

So, I'm commuting in & out of town all week. When I get home, my wife mentions that the car is making a funny noise. I take it for a spin, don't notice anything in particular. Then I stop to get the mail, and as I pull a u-turn it makes a funny "clunk" and then a horrible metal on metal sound. I limp home, about 2 blocks.

Question about front bearings: Is 1/2" play considered excessive?

Anyway, as per the attached image, the front bearing has completely disintegrated. Lucky it happened so close to home.

Will the standard bearing kit be enough?
