Slight clunk when rocking the wheel

[kalum0101]

Good afternoon

Have a slight issue with my Vectra where when you rock the wheel back and fourth while stationary, it's makes a slight clunking sound. I've also heard it when parking when I'm turning the wheel slowly.

I had my track rod ends inspected the other day and while the garage said one was a little stiff, they didn't seem worn out. Could it be this or something else. Any help is greatly appreciated.
