Lift it, take the wheel off, and remove the steering arm tie-rod (use a Big F%@&ing Hammer). Attach a spring scale to the hole in the steering arm and record the pull required to keep the knuckle assembly turning after starting from the initial straight ahead position. The pull should be between 20 and 25 lbs in either direction. Adjust the balljoint by removing the upper balljoint stud nut and turning the adjusting sleeve. Reinstall the nut and tighten it to 50 ft-lbs. Than put everything back. This has all been plagiarized from a Haynes manual. Maybe you should buy one. lol
