All of a sudden...click, click, click goes the right front wheel?

Hello all! Hope I can get some clues/help as to what is going on...

Wife took the cart for a spin and came back with the report that the front right wheel is clicking?

The sound is definitely from the front right wheel and clicks while in reverse and or forward.

Any ideas on what might be the problem?

Thanks!

PS- 2007 PDS cart 36 volt...used primarily on smooth asphalt and a dirt path for 9 holes of golf.
