I hate that (losing track)
The mystery
Some of those mysteries are good
We had a Taurus under base warranty, not my ticket but we all got involved. It vibrated so bad at freeway speed; it would shake your fillings out. They did everything, balanced the tires, replaced the CV joints and wheel bearings, they even had the trans guy R&R the trans and replace the final drive bearings. That's when they gave it to me (the alignment guy). I drove it and told the tech to balance the tires again. He squawked but we both went and did it. The LF tire was only .25 oz. out of balance. I told him to spin it again, it was 4 ounces out, we spun it again and it was 3 ounces out. I told him to break down the tire and lets see. Damn thing was full of three cans of fix a flat.
