2004 Chevrolet Colorado drivetrain & axles problems

The first and ongoing problem grinding in front left, driver, side wheel area. Many attempts have been made to fix this problem, they started out changing the whole front end, along with alignments, after some adjusting the problem will seem to go away only to return with in 2 months second, tires worn from inside out alignment, new tires, I was told one reason was the truck was dirty. I do not feel this is a reason for tire wear. New tires same problem. Third, truck not engaging when shifted into gear.
