Camber Adjustment Bolt Package Installation

CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION (WITH ACR PACKAGE)

NOTE: The following procedure should only be used on the front suspension of vehicles WITH the ACR competition package. For installation of the adjustment bolt package on the ACR rear suspension, refer to CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION (WITHOUT ACR PACKAGE).
The camber adjustment bolt package contains new bolts and nuts for attaching the strut clevis bracket to the steering knuckle. The bolts contained in the package are slightly undersized allowing for movement between the strut clevis bracket and the steering knuckle. The movement allowed by the undersized bolts provide approximately two degrees of camber adjustment per side of the vehicle. Additional modification will also be necessary to gain a proper camber setting for ACR competition. To modify the strut, install and adjust the camber adjustment bolt package, follow the procedure below.

CAUTION: There are separate camber adjustment bolt packages for the front and rear of the vehicle. Be sure to use the correct package for the front suspension.

1. Raise the vehicle until its tires are not supporting the weight of the vehicle.

CAUTION: The knuckle to strut assembly attaching bolt shanks are serrated and must not be turned during removal. Remove the nuts while holding the bolts stationary.

2. Remove the wheel and tire assembly at the strut requiring modification.
3. Remove the original upper and lower bolts attaching the strut clevis bracket to the knuckle.
4. Separate the knuckle from the strut clevis bracket.

NOTE: The following two steps must be performed to gain the necessary amount of negative camber for ACR competition.





5. Draw an imaginary line from the center of the clevis bracket upper bolt hole down through the center of the clevis bracket lower bolt hole. Pivoting the line at the center of the lower hole, move the upper end of the line inward so as to follow an arc past the inner edge of the upper bolt hole approximately 1.4 mm (0.056 inch). Mark the bracket showing what area of the surface needs to be removed to form the elongated hole. Remember, this elongation must follow the arc. Repeat this step on the opposite side of the clevis bracket.
6. Using an appropriate grinding tool, elongate the upper hole as indicated by the markings until the necessary material is removed. Repeat this step on the opposite side of the clevis bracket.
7. Place the knuckle back in the clevis bracket.
8. Install bolts from the adjustment package into the holes where the original bolts were removed. Install the bolts from the rear.
9. Install a nut provided in adjustment package on each replacement bolt. Tighten the nuts until snug, but still allowing the knuckle to slide in the clevis bracket.
10. Reinstall the tire and wheel assembly.
11. Perform the above procedure to the remaining front strut as required.
12. Lower the vehicle and jounce the front and rear of the vehicle.
13. Adjust the front camber to the preferred setting by pushing or pulling on the top of the tire. When camber is set to specifications, tighten the upper and lower strut clevis bracket bolts. Again jounce the front and rear of the vehicle, then verify the camber settings.
14. Torque front strut clevis bracket-to-steering knuckle attaching bolts to 53 Nm (40 ft. lbs.), plus an additional 1/4 turn after the torque is met. Torque the rear strut clevis bracket-to-rear knuckle attaching bolts to 95 Nm (70 ft. lbs.).
15. Once camber is within specifications, adjust toe to meet the preferred specification setting.
