    10.  
    11. While the brakes are applied, loosen and remove the hub nut on the end of the driveshaft.
    12.  
    13. Release the brakes.
    14.  
    15. Remove the front disc brake caliper and adapter as an assembly, and the brake rotor from the steering knuckle.
    16.  
    17. Remove the nut attaching the outer tie rod to the steering knuckle. To do this, hold the tie rod end stud with a wrench while loosening and removing the nut with a standard wrench or crowfoot wrench.
    18.  
    19. Remove the tie rod end from the steering knuckle using Remover, Special Tool MB991113.
    20.  
    21. Remove the tie rod heat shield.
    22.  
    23. Remove the nut and pinch bolt clamping the ball joint stud to the steering knuckle.
      CAUTION
      The strut assembly-to-steering knuckle attaching bolts are serrated and must not be turned during removal. Hold the bolts stationary in the steering knuckles while removing the nuts, then tap the bolts out using a pin punch.

    24.  
    25. Remove the 2 bolts attaching the strut to the steering knuckle.
      WARNING
      Use caution when separating the ball joint stud from the steering knuckle, so the ball joint seal does not get cut.

    26.  
    27. Separate the ball joint stud from the steering knuckle by prying down on lower control arm and up against the ball joint boss on the steering knuckle.
      NOTE
      Do not allow the driveshaft to hang by the inner CV-joint; it must be supported to keep the joint from separating during this operation.

    28.  
    29. Pull the steering knuckle off the driveshaft outer CV-joint splines and remove the steering knuckle.
      NOTE
      The cartridge type front wheel bearing used on this vehicle is not transferable to the replacement steering knuckle. If the replacement steering knuckle does not come with a wheel bearing, a new bearing must be installed in the steering knuckle. Installation of the new wheel bearing and hub must be done before installing the steering knuckle on the vehicle.

    30.  
    31. If the wheel bearing and hub need removal. Do not reuse the wheel bearing.
