    Before connecting the lower ball joint to the knuckle, degrease 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. Never align the castle nut by loosening it.
    Install a new lock pin on the castle nut after tightening.
    Use a new spindle nut for 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.
This details will help.
