  Q: How to Properly Service and Repair a Control Arm on Mercury Grand Marquis?

  A: The replacement of upper control arm suspension fasteners must incorporate new parts that match the original numbers or equivalent standard since poor substitute parts will produce major system breakdowns. The correct reassembly occurs when you follow given torque values to achieve proper retention. Maintenance should begin with turning off the air suspension system electrical power because air spring inflation or deflation could result in unexpected vehicle shift. All vehicles with fire suppression systems require the system to be placed in a depowered status. The technician should position the vehicle into NEUTRAL on a hoist before removing the shock absorber and spring assembly. First detach the wheel speed sensor retainers from the upper arm then remove its two nuts and two bolts while disposing of the old parts. The fasteners on the new upper arm must be tightened to 150 Nm (111 ft. lbs.). The initial step involves tightening fasteners on both upper arm-to-crossmember attachments along with shock absorber components only until the entire installation process concludes and wheel assembly weight activates. The front end alignment requires checking after final installation completion. The driver needs to activate the fire suppression system power after the service work ends.

  Q: How to service the Sway Bar Link on Mercury Mariner?

  A: Vehicle positioning on a hoist in NEUTRAL mode is required prior to service operations on the sway bar link. The hex holding feature can stop the ball stud from rotating while you take out the upper sway bar link nut that needs to be torqued to 63 Nm (46 ft. lbs.) for installation. A second application of the hex holding feature will let you remove the lower sway bar link nut before tightening this fastener to 55 Nm (41 ft. lbs.) during installation. Check the wear of sway bar link ball joints and boots before changing the parts to new ones. Last, achieve the removal of the sway bar link then install either new parts or inspected components simply by reversing the disassembly process.

  Q: How to Ensure Proper Functionality of the Seat Switch in a Mercury Cougar?

  A: Service and repair of the power seat switch requires a waiting period of at least one minute after disconnecting the battery cables to avoid accidental air bag deployment while disconnecting electrical connectors from the electronic air bag control module or any supplemental restraint system electric connections. Start repairs by disassembling the front seat yet retaining the outer seat base cover requires unscrewing hardware followed by cutting the retaining clip above and which needs to be unlatched alongside the front retaining clip. The next step includes disconnecting the electrical connector after removing the wiring harness from under the seat body. You should remove the power seat control switch by using a trim tool to uninstall the control knobs followed by removing two retaining screws found at the back of the seat base cover. When installing replace all parts in the opposite order of removal.

  Q: How to Inspect and Repair the Air Bag Supplemental Restraint System (SRS) After a Collision on Mercury Marauder?

  A: A thorough examination and repair of the supplemental restraint system (SRS) becomes necessary whenever it has deployed in a collision. The SRS should be deactivated before service work allows the installation of restraint system diagnostic tools. Reconnection of the air bag modules takes place after system activation so non-deployment incidents during subsequent collisions are prevented thus preventing personal injury. The driver air bag module removal procedure requires the disposal of original bolts with new hardware for installation while respecting that initial build vehicles might have shorter bolts than the supplied parts. All restraint system diagnostic tools should be taken out from the vehicle after finishing the diagnostics or repairs to SRS and seat systems prior to vehicle operation. The vehicle cannot be handed over to the customer unless the SRS operates without issues. Replacing the RCM becomes mandatory when deployable devices such as the driver air bag, passenger air bag, seat side air bag or safety belt pretensioner become deployed while triggering DTC B1231 (Crash Data Memory Full) in the RCM. The repair process requires attention to both impact sensor mounting points and hardware components when such elements display symptoms of damage. The replacement of a new Clock Spring remains necessary in cases where the driver air bag module needs to be replaced. Check the vehicle thoroughly to find all damages starting with the steering column then moving to instrument panel knee bolsters and their mounting points followed by instrument panel braces and brackets leading up to instrument panel and mounting points before inspecting seats and their mounting points and safety belts and supporting components including safety belt buckles and retractors with SRS wiring as well as harnesses and connectors. The inspection should be followed by replacement or repair of damaged components.
