  Q: How to service and repair the steering knuckle on Lincoln MKX?

  A:

  Start the steering knuckle service procedure by removing the tire together with the wheel. To stop halfshaft rotation apply the brake before going ahead with any discarding of either the wheel hub nut or washer. Remove the wheel hub nut in addition to the washer and halshaft hub seal while discarding the seal itself. Extract the wheel speed sensor bolt from the knuckle then set the sensor to the side. Secure the caliper by supporting it with mechanic's wire to prevent damage to brake hoses before removing the two anchor plate bolts. You should now use the Front Hub Remover to split the halfshaft from the wheel hub after taking off the Brake Disc. Divert each component of the tie-rod end including the pin and nut while utilizing the Tie-Rod End Remover to remove the part from the knuckle structure but never hit the part with a hammer. Begin by removing the Shock Absorber lower nuts together with flag bolts then proceed to remove lower ball joint bolt and nut which should also be discarded. The wheel knuckle receives its position after which the mechanic installs a new lower ball joint bolt and nut then tightens the nut to 55 Nm (41 lb-ft). Use the same tool to tighten new shock absorber lower flag bolts and nuts to 225 Nm (166 lb-ft). Place the tie-rod end while installing a new nut and cotter pin and tightening to 48 Nm (35 lb-ft). Secure the wheel speed sensor bolt at 7 Nm while using 62 lb-in as torque measurement. The brake disc installation should be followed by placing the Brake Caliper and anchor plate assembly while tightening its two bolts to 133 Nm (98 lb-ft). The crew must seat the halfshaft inside the hub with the original wheel hub nut and washer while tightening it to 350 Nm (258 lb-ft) before disposing of the nut and washer. Start tightening of the wheel hub nut combined with its washer to 350 Nm (258 lb-ft) within a five-minute deadline from initial thread engagement to activate locking chemicals. Put on the wheel and tire before performing necessary checks on the front end alignment.
