Yeah CV joint, get on your knees at the front of your car and look near the inside of the wheel.
I rekon you will have a busted CV boot and it's gotten dry and is now clicking.
The reason it is clicking is because the barings in the CV joint are getting hot and knocking into each other as it tries to spin I believe.
Fix it, a busted one is an MOT fail and it's not a big job.
