Tie rod
Worn front axle and/or front end component.
Could be the CV joint is dry or has failed.
Assuming this is an older car a knocking noise on turning could mean one of the drive shafts is worn. Other things to check - are the bolts tight on the front wheels, if a very high mileage it could be worn wheel bearings.
A knocking/clicking noise when making a turn is a sign of a torn CV boot. In this case it's the driver side boot that is torn.

Could be a bad CV joint or bad wheel bearing C.V. Joints need replacing
i have a grinding noise on the front left wheel. i have taken the calipa off and i have one brake pad that is shot. could it be that or can it still be the bearing. how can i find out.
Turning right loads the left front wheel of the vehicle, so if you hear the knock when you turn right the bad CV joint is on the left, and vice versa.
a dog
It could be the bearings on your front driver side wheel.
check wheel bearings and cv joints if applicable
A front popping on the left of a 98 Blazer could be the brakes, steering, or wheel bearing. Check all three to find the cause.
