Our 2011 scab alignment through 68K miles was perfect - could take my hands off the wheel and run straight-line 'til lunch. But swapped it in on a 2015 SCREW, and at just over 2500 miles, if I take my hands off the wheel I make for the rumble strip right quickly. It does occasionally want to wander to the left, but mostly goes right.

Haven't been back to the dealer yet, but have a list for when I do go back.

Any others with same? Get satisfaction?

Mine is straight, you might try doing a tire rotation first and see if its a tire pull. More common that you would think.

 

After I had my level kit put on, I took it to a private shop. They spent hours trying to get it right with no luck. I took it to the dealer, he had no problems getting it straight as an arrow.

 

Good to know. Did they give you any hassle about warranty being you modified the truck?

 

No. My dealer installs them as well.
