Firm feel steering improvement?

Now you are doing exactly what I warned against.........making assumptions. There is no "inherent play" in worm gear systems any worse or different than any other type steering. If you are unhappy with the "play" you need to go back over the system and find out what "it is."

Also keep in mind that tires (the type, the size, the quality, etc) will make a TREMENDOUS difference in the "feel" of steering. Even with raidials, some tires give a "sloppier" feel to the front end and handling. Also keep in mind that REAR suspension problems can easily be mistaken for "front end slop". Something as simple as a loost/ worn leaf shackle.
