Recently, I realized that my bike front wheel axle is making clicking sound.
Now, i am trying to resolve the problem.
Do I need to put a grease(special oil),
or I need to buy new front wheel axle,
or I need to change ball bearings.
I am a novice in this.
Lift the front wheel off the pavement and spin the wheel so that it moves freely. If you are hearing a clicking sound and/or the wheel visibly slows slightly in conjunction with the sound then you may have a bearing problem. You could open it up and repack the bearings. By repacking I mean clean out the old grease and put new grease on the bearings. There should be enough grease that the bearings don't fall out of their ring if turned upside down but no more than that. Do not use oil. Grease is what to use for bearings. Close everything up and reinstall the wheel. It should be a little bit sluggish for the first few spins because the grease is getting settled into place. Should be good to go from then on. Make sure you inspect each bearing for damage/rust. If either is found then you need to replace the bearings as well. Good luck.
