Clicking noise coming from front driver side wheel/tire as car is in motion. Sounds almost like there is nail/screw stuck in the tire. Upon inspection, i didnt find anything stuck in the tire. What is this clicking noise?

Wheel bearing is bad and will need to be replaced. This is a somewhat easy job if you are comfortable with mechanics, but you will need to remove a lot of parts to get at the bearing. You can get a new bearing at your local auto parts store. Please rate

A bad cv joint. Look under the car on the inside of the front wheel. There will be a shaft extending from the transaxle to the wheel hub with black rubber accordion boots on either end of it. Look for the boot for breaks or cracks. Look around the area for wheel bearing grease (very thick and sticky) to be splattered all over. Sometimes the boot is intact and the joint may still go bad but cv joint has an 8 hour life once the boot breaks. Replace the cv joint and boots. Buy a rebuilt one from your local parts store. They will be affordable and reliable.
