Q: Vehicle pulls to the right/left

I have an issue with my 2009 Hyundai Elantra with 111000 miles on it. The vehicle pulls to the right constantly and I need to use some light force to keep the steering wheel from drifting. I also noticed that it is harder to steer in the left direction. But the issue does not end there, sometimes the vehicle also pulls to the left and I have to recenter and hold the steering wheel to make it go straight. I had the wheels aligned twice, rotated the tires etc. but the issue still persists. I the took it to a local mechanic who looked underneath the car and told me that there was no problem. I did notice that when the car is lifted with the wheels of the ground, the front left wheel doesn't move as freely i.e it jerks when I try to move it. I dont believe its the brakes since they were recently replaced and also hard braking doesn't cause the vehicle to drift. I cant pinpoint where the issue is. Could you give me some pointers on where to have the mechanic look?
