Uneven steer tire wear

[MPDiagnostics]

You should also check for excessive play in the wheel bearings and kingpins. Something I like to check for when looking at uneven tire wear. Its not hard. Jack up the wheel in question at least 1-2 inches off the ground. Insert a pry bar under the tire and lift up and down with the bar. Have someone else watch the steering knuckle joints for any movement. There is an acceptable amount but I usually like to see no play at all. Have seen this cause issues before. If you can feel play but see no movement in the kingpins then most likely you have bearings that need to be looked at. Another tip is to try checking the kingpins before you grease them. Sometimes the grease will take up the play and can give you false readings.
