Rack and pinion play
Turn the engine on. Check for leaks. Repeat the lock-to-lock turns roughly three times and return the steering wheel to center. Cut off the engine. Check the ps reservoir. Any air in the system should have been purged and turned the ps fluid slightly frothy. When the trapped air is gone, re-check the ps reservoir's level and top off as necessary. Repeat procedure with the engine on until all air is purged from the system. Once you completed this procedure, just check the ps reservoir's cold level periodically to make sure that you're not losing fluid during normal driving.
Good luck!
