  Q: How to service and repair the Steering Shaft on Mercury Mariner?

  A: The repair or service of steering column shaft starts with removing the steering column opening trim and the left-hand instrument panel side finish panel. Remove the ground wire eyelet bolt through the side finish panel opening before placing the two ground wire eyelets and wires properly in position. Disconnect the two wiring harnesses on the instrument panel while you also detach the high-voltage jumper switch electrical connector (if present) and place all hardware to the side. Follow this procedure to gain access to the steering column coupling-to-steering column bolt during removal then discard it and tighten the new bolt to 55 Nm (41 lb-ft) when installing. Press the Ignition Switch to lock and remove the key so you can turn the Steering Wheel opposite to its original position while the column keeps itself locked. Steering column shaft rotation needs to be prevented when the lower shaft is separated from the installation as this movement will damage the Clock Spring; rotating the shaft requires Clock Spring recentering for repair. First detach the coupling between the steering column and column before removing three steering column dash seal nuts for new installation where final torque should be set at 8 Nm (71 lb-in). Passengers should move the dash seal up the steering column shaft from inside the compartment before discarding the steering column coupling-to-steering column shaft bolt. They must tighten this new bolt to 55 Nm (41 lb-ft) when installing it. Take out the steering column shaft and dash seal for inspection of the dash seal along with clip-type retainers for potential damage before getting a new dash seal if needed. The reverse steps of the removal process will finish this operation.
