  Q: What are the crucial steps to follow when servicing the steering knuckle on Mercury Grand Marquis?

  A: During steering knuckle servicing it is mandatory to replace suspension fasteners with new components that use either identical part numbers or equivalent quality standards to prevent component failure that triggers large service costs. The correct retention depends on strictly meeting torque specification requirements during reassembly procedures. You need to switch off the Air Suspension system electrical power to stop unexpected air spring inflation or deflation which may cause vehicle shifting during hoisting, jacking and towing. Before continuing with the operation vehicles with fire suppression systems must have their depowering process initiated. Perform the procedure on a hoist with the vehicle in NEUTRAL positioning until you remove the wheel bearing along with the Wheel Hub. Enable holding on the stud when you detach the tie-rod nut for safety reasons until you reach 80 Nm (59 lb-ft) torque during final installation. Discard the upper stabilizer bar link nut before installing the new one by tightening it to 63 Nm (46 lb-ft). Remove first the lower stabilizer link nut along with the stabilizer bar link before installation when you should discard the nut and install your new one by tightening it to 55 Nm (41 lb-ft). Detach the wheel speed sensor wiring harness retainer from the steering knuckle before removing the upper ball joint nut for the replacement with the new one that requires a torque of 150 Nm (111 lb-ft) during installation. As the last step detach the lower ball joint nut and wheel knuckle then discard the nut before tightening the new one to 150 Nm (111 lb-ft). The service ends by checking front end alignment while following removal steps in reverse order. Repower the fire suppression system only if applicable.
