Corvette (1970-73) (Rear Wheels): Toe-In

Rear wheel toe-in angle is adjusted through use of variable thickness shims inserted between torque arm and frame side member web at forward pivoting joint. Shims are slotted to slide over bushing pivot bolt on either side. To adjust toe-in, loosen pivot bolt, shim outboard gap as necessary to obtain solid stack-up between outer end of torque arm bushing and inner wall of frame side member, and when adding shims to inner side of control arm do not use thicker shim than necessary or force insertion of shim as this may cause toe-in setting to change. After shims are securely installed, tighten pivot bolt to 40-60 ft. lbs. (1963), 45-55 ft. lbs. (1964-69).

Caster and camber adjustments are made by adding or removing shims at upper control arm inner shaft and mounting bracket bolts. After adjustment is completed tighten shaft bolts to 100-150 ft. lbs. (1964 Exc. F-85), 60-85 ft. lbs. (1964 F-85), 75 ft. lbs. (1965-67), 50 ft. lbs. (1968-70), 50 ft. lbs. (1971-72 F-85), 75 ft. lbs. (1971-72 88, 98 Series), 50 ft. lbs. (1973 Omega), 85 ft. lbs. (1973 Cutlass, 88, 98 Series).
