  3. Raise and safely support the vehicle.
  4. Remove the right front tire assembly. Remove the right inner fender access cover.
  5. A flywheel holding device such as GM's J 37096 is required to keep the crankshaft from turning as the crankshaft balancer is being removed. Install this holding tool or its equivalent. Please see for more information.
