Hey guys just recently changed my brakes on the rear of my 2010 and realized that I had a lot of play on my right side. I was wondering if I needed to replace the whole knuckle or just the bearing and if any has any DIY on it.

 

is the play just left to right or is up and down as well? if up and down as well it would be your bearing

 

It moves all around

 

Sounds like you need to do suspension refresh. control arms first. Then see if hub giving you issues. If you still have play, bearing next. Alignment critical after any suspension work.
you should have no play holding wheel 12/6 or 3/9 locations.

 

I ordered a used knuckle off ebay, the car activates multiple faults such as abs/chassis/psm which I'm sure the bearing has kicked the bucket. All other suspension parts look good upon inspection.

 

Wheel bearing was definitely shot, decided to also go with a lower mileage spindle. All system faults see gone and there is zero wheel play. In case anyone wants to prevent this before you're without a car, my warning sign was a weird scraping noise I couldn't figure out where it was coming from after encountering a dip in Denver. Mileage is 111k+.

 

thanks for the update
