Driveway alignment

[kyleag89]

Hey guys I was trying to give my 2011 sierra 1500 an alignment in my garage and ran into an issue.  I usually use string line and some jack stands to create a perfect rectangle box around the 4 wheels to measure from but it doesn't work for my truck!  My rear axle is either crooked and/or off center enough that I can't get the front and rear tires to line up parallel with the string line.  Has anyone ran into this before?

Unless I'm doing something wrong if I line my front tires up with the rear it's quickly obvious that something isn't right and my truck starts driving hard right.  I ended up using my seat belt to hold the steering wheel centered and then adjusted my tie rods to center on the threads on both sides then adjusted toe by just measuring the front and rear of the tires with 2 tape measures.

Lots of GM trucks have a wider front axle than the rear

Take it for a proper computer alignment.
