Need help fixing front wheel assembly

[radius2000]

Hi,

I got this lawn mower about 10 months ago: Craftsman 160cc Honda engine, 22" Front Drive Self-Propelled

Today it hit a rock and one of the front right wheel assembly got lose. The wheel still moves but it does not stay in its place (height wise).

I've attached few photos. Any idea how to get this fixed?

Thanks!

Can you get a pic of the lever that snaps into the detentes and holds the wheel at the selected height?

I can't see anything wrong in the pics. Does the lever still have strong tension against the bracket where the holes or notches are? I think you're going to need to remove the wheel to see what's going on.
The right front wheel on my exmark did this when I first got it. I had to take it all apart and rebend the lever in order to get enough tension to hold the pin in the lever in the holes in the bracket.

Take that adjustment lever and just bend it in, it will be even stronger then before

I took apart wheel assembly and discovered that bearing assembly is broken.
