2003 Chevrolet Suburban Alignment Specs

Introduced in 1935, the Chevrolet Suburban is one of the longest-running vehicle models in history. While it has gone through numerous redesigns and adopted countless innovations since its early years, the Suburban remains a popular full-size SUV. The 2003 Chevrolet Suburban came in Suburban 1500 and Suburban 2500 trims. The two-wheel-drive and four-wheel-drive trims of the Suburban 1500 had different alignment specs, while all trims of the Suburban 2500 shared the same alignment specs for 2003.

The 2003 2WD Suburban 1500

The caster angle on the front left wheel should be set at +3.9 degrees, but the caster angle on the front right wheel can range from +1.0 degrees to +4.7 degrees, with a cross tolerance of -0.8 degrees for the left wheel and +0.75 degrees for the right wheel. The camber angle can range from +0.25 degrees to +0.50 degrees on each of the front wheels, with a cross tolerance of zero to +0.5 degrees. The front toe-in can range from +0.1 degrees to +0.2 degrees. The rear end alignment is not adjustable.

The 2003 2WD and 4WD Suburban 2500s

The caster angle on the front left wheel should be set at +4.5 degrees, but the caster angle on the front right wheel can range from +1.0 degrees to +4.75 degrees, with a cross tolerance of -0.25 degrees for the left wheel and +0.75 degrees for the right wheel.
