Repair 7

Chevrolet applied the S-10 prefix to two different vehicles starting in the 1980s: the Chevy S-10 Blazer SUV and the Chevy S-10 pickup truck. The S-10 prefix is most synonymous with the pickup truck, which sported the S-10 brand from 1982 until it was discontinued in 2004 and was often referred to simply as the S-10.

General Alignment Information of the Chevy S-10

The 2004 model year is the last year for which S-10 alignment specs are available, and the 2004 specs only apply to S-10s produced that year. When adjusting the alignment of a vehicle, it is absolutely necessary to ensure that the proper alignment specs are used not just for a particular model but also for the appropriate year. For instance, the alignment specs for a 1987 S-10 differ substantially from those for a 2004 S-10. In some instances, alignment specs vary from trim to trim of a particular vehicle in a given model year, and they can even vary based on optional suspension packages. The rear alignment is not adjustable on any trim of the 2004 S-10. All two-wheel-drive and four-wheel-drive trims of the 2004 Chevrolet S-10 shared the same alignment specs for the front end, but it is imperative to consult an owners manual, repair manual or certified mechanic to make certain the correct specs are used.

Caster

The caster angle on the front left wheel of the 2004 S-10 can range from +1.8 degrees to +3.8 degrees, with the ideal setting being +2.8 degrees, with a cross tolerance of +0.5 degrees. The caster angle on the right front wheel can range from +2.3 degrees to +4.3 degrees, with the ideal setting being +3.3 degrees, with a cross tolerance of +0.5 degrees. The difference in the two settings is intended to compensate for public roads being crowned at a slight downward slope toward the outside of the lane to facilitate drainage.

Camber

The camber angle on the front end of the 2004 S-10 can range from -1.0 degrees to +1.0 degrees, with zero being the ideal setting, with a cross tolerance of +0.5 degrees.

Toe-in

The toe-in on the front end of the 2004 S-10 can range from -0.1 degrees to +0.3 degrees. The ideal setting is +0.1 degrees.

Produced by General Motors in USA, the Chevy Blazer is a mid-sized sport utility vehicle (SUV). It could be equipped with several different types of engines. All Blazer SUVs require periodic adjustment, often referred to as "alignment." The factory specifications for the alignment are the same for all 1991 Blazer models. These specifications are given for a vehicle at curb height with one-half tank of fuel.

Camber

Measured in degrees, camber is the outward or inward tilt of the wheel in relation to the center of the vehicle. The Blazer camber angle should be the same on both left and right wheels. Camber angles must be +0.8 degrees with the measuring accuracy of 0.80 degrees.

Caster

Caster is both the rearward and the forward tilt of the steering knuckle from the true vertical. Caster is the measurement in angles that is responsible for directional stability. The Blazer caster angle should be the same on both left and right wheels. The angle must be +2.0 degrees with the maximum allowable difference of 1.00 degree.

Toe

Toe is the difference between the leading and trailing inside edges of the front wheels. Total angles on all 1991 Blazer models must be +0.15 degrees with measuring range of 0.10 degrees. Toe-in-left and right side should be set separately per wheel and steering wheel must be held in straight ahead position within 5.0 degrees.
