  16. Remove the driveshaft outboard joint (C) from the knuckle (D) by tapping the driveshaft end (E) with a plastic hammer, then remove the knuckle.
    NOTE: Do not pull the driveshaft end outward. The inner driveshaft joint may come apart.
  17. Separate the hub (A) from the knuckle (B) using the special tool and a hydraulic press. Hold the knuckle with the attachment (C) of the hydraulic press or equivalent tool. Be careful not to deform the splash guard. Hold onto the hub to keep it from falling when pressed clear.

  26. Install the knuckle in the reverse order of removal, and note these items:
    • Be careful not to damage the ball joint boot when installing the knuckle.
    • Tighten all mounting hardware to the specified torque values.
    • Before connecting the lower ball joint to the knuckle, decrease the threaded section and tapered portion of the ball joint pin, the lower arm connecting hole, the threaded section and mating surface of the castle nut.
    • First install all the components and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
    • Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
    • Install a new lock pin on the castle nut after torquing.
    • Use a new spindle nut on reassembly.
    • Before installing the new spindle nut, apply a small amount of engine oil to the seating surface of the nut. After tightening, use a drift to stake the spindle nut shoulder against the driveshaft.
    • Before installing the brake disc, clean the mating surfaces of the front hub and the inside of the brake disc.
    • Before installing the wheel, clean the mating surfaces of the brake disc and the inside of the wheel.
    • Check the front wheel alignment, and adjust it if necessary (see WHEEL ALIGNMENT ).
