97 Blazer Alignment Specifications
Chevrolet introduced the Blazer in 1969 as an SUV version of its full-size pickup truck. The early Blazer evolved into the Chevy Tahoe, and Chevy applied the Blazer name to a new mid-size S-10 SUV in 1983. Chevrolet introduced a newly-designed second generation of the S-10 Blazer in 1995, and the Blazer remained basically the same for the next 10 years. The 1997 Chevy Blazer came in two-wheel-drive and four-wheel-drive trims, but the alignment specs were the same for both. Chevy discontinued the Blazer in 2005.
General Information
The caster, camber and toe-in were adjustable on the front end of the 1997 Chevy Blazer, but not on the rear end because the vehicle came with a fixed rear axle.
Caster
The caster angle measures the forward or rearward slope of the line between the upper and lower steering pivots on a vehicle when viewed from the side of the vehicle. The caster angle on the front end of the 1997 Blazer can range from +0.5 to +3.0 degrees, with the ideal setting being +1.75 degrees with 0.5 degrees of cross tolerance.
Camber
The camber is the vertical angle at which the front wheels of a vehicle lean when viewed from the front of the vehicle. If the the top of the wheel leans out, the camber angle is positive. If the top of wheel leans in, the camber angle is negative. The camber angle on the front end of the 1997 Chevy Blazer can range from zero to +0.5 degrees, with the ideal setting being +0.25 degrees with 0.5 degrees of cross tolerance.
Toe-in
The front wheels of most vehicles are set so that the fronts of the tires will angle slightly toward one another to help take tension off of the wheel bearings. This slight angle is known as the toe-in. The toe-in on the front end of the 1997 Chevy Blazer should be set at +0.1 degrees.
