Alignment specifications for all 1987 GM passenger cars are being published in this bulletin due to some recent specifications changes. Many of the recent changes have been reductions in toe for improved tire wear. The chart below (also attached) replaces and supersedes the alignment specification chart printed in the November 1986 Service Guild.

Four-wheel alignment is recommended whenever rear suspension is adjustable. Four-wheel alignment equipment, such as in the GM Dealer Equipment Catalog, is recommended. Alignment equipment must be calibrated on a regular basis.

1987 GM PASSENGER CAR ALIGNMENT SPECIFICATIONS

Front Wheel Drive (FWD)
NOTES: All specifications, including toe, are in degrees. All toe specifications are total (sum) toe with appropriate steering wheel or thrust angle requirements. (Individual toe may be obtained by dividing total toe in half Ex: .1~ +/- .2~ total toe = .05~ +/-.1~ individual toe). Positive toe is toe-in. Cross caster equals left caster minus right caster. Cross camber equals left camber minus right camber. Thrust angle is the angle between the path the rear wheel will take and the car's centerline.
