Front Seat Track Motor: Installation
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
- Position the new and old seat track motor assembly side by side. Position the new seat track motor assembly stub shaft flat spots (splines) in the same position as the old seat track motor assembly flat spots. If necessary, apply power and ground to the new seat track motor electrical connector as shown during removal to obtain the same position.
Install the seat track motor assembly to the upper support assembly.
- Install the seat track motor assembly pivots through the front and rear height adjustment gear brackets.
- Apply multi-purpose grease to the motor pivots.
- Mesh the seat track motor assembly gears to the front and rear height adjustment gears.
NOTE: Make sure the motor is positioned right side up.- There should not be a gap between the upper support assembly gears and the seat track motor assembly housing.
- Install the seat track motor assembly pivots through the front and rear height adjustment gear brackets.
- Install the support straps.
- The support straps must fit flush against the front and rear height adjustment gears.
- Check to make sure the index marks on the outboard track C-channel and plastic coated slide are still in alignment.
- Position the pinion cage onto the outboard track.
- Install the outboard track.
- Position the track studs through the seat track motor assembly.
- While sliding the track studs through the seat track motor assembly, position the pinion cage opening around the seat track motor assembly gear.
- Fit the support straps and seat track motor assembly gear bushing alignment pins into the track openings.
- When assembled, make sure the outboard track, support straps, front and rear height adjustment gears and seat track motor assembly all fit flush against each other.
- Make sure the support straps and seat track motor assembly gear bushing alignment pins fit into the track openings.
- Install the two bolts holding the seat track motor assembly to the outboard track.
- Install the two nuts.
- Install the outboard retainer clip.
- Check to make sure the index marks on the outboard track C-channel and plastic coated slide are still in alignment.
- The index marks on the outboard track C-channel and plastic coated slide must align at this step. If the index marks do not match up, repeat Steps 1 through 9.
- Check to make sure the index marks on the inboard track C-channel and plastic coated slide are still in alignment.
- Assemble the seat track motor assembly, upper support assembly and inboard track together.
- Align the drive tube to the motor stub shaft. Tap the nose of the inboard track gear toward the seat track motor stub shaft.
- Positioning a block of metal or wood behind the motor gear can aid assembly.
- While tapping the parts together, simultaneously engage the front and rear lift links to the inboard track.
- When the lift links are up against the inboard track, with the bushings through the hole and seated, the drive tube is fully engaged.
- Align the drive tube to the motor stub shaft. Tap the nose of the inboard track gear toward the seat track motor stub shaft.
- Install the nuts holding the inboard track to the upper support assembly lift links.
- Check to make sure the index marks on the inboard track C-channel and plastic coated slide are still in alignment.
- The index marks on the inboard track C-channel and plastic coated slide must align at this step. If the index marks do not match up, repeat Steps 11 through 13.
- Position the seat track in the vehicle.
- The left and right front mounting feet holes should align with the floor pan mounting holes, without pushing or pulling the seat track to force alignment. Check the witness marks (indentations) in the carpet. The tracks should line up closely with them.
- If the seat track does not align to the vehicle, check to make sure the index marks on the inboard and outboard track rails and guides are still in alignment. Repeat the necessary steps until the index marks align.
- Using suitable tools, support the seat track gear rack on each side of the roll pin location as shown. Install the roll pin into its original position.
- Attach the seat motor wire harness to the seat track, then position each of the three memory seat position sensors (if equipped) and rotate clockwise to install.
- Position the climate controlled seat module onto the bracket and install the two bolts.
- Position the electrical connector bracket and install the two bolts.
- Position the memory seat module and install the two bolts (if equipped).
- Position the seat track position sensor and install the two bolts.
- Position the two side shields onto the seat track and install the two rear pin-type retainers.
- Install the two front pin-type retainers.
- Install the seat track. For additional information, refer to FRONT SEAT CUSHION - DRIVER or FRONT SEAT CUSHION - PASSENGER .
- Install the seat and activate. For additional information, refer to DRIVER SEAT .
- Cycle the seat in its full range of travel in all directions.

NOTE:
This step is critical in getting the inboard and outboard tracks in alignment. Otherwise, when installing the seat in vehicle, the holes in the track mounting ears will not align to the holes in the floor pan and the seat track may prematurely fail due to binding.
NOTE:
The front and rear height adjustment gears do not have to mesh with the seat track motor assembly gears at the same teeth as when disassembled.

WARNING:
The support straps are load-bearing components during a crash event. The support straps must be correctly installed during assembly of the seat track. Failure to follow these instructions may result in the failure of the seat to perform as designed with resultant risk of personal injury to the vehicle occupant.
WARNING:
The pinion cage is a load-bearing component during a crash event. The pinion cage must be correctly installed during assembly of the seat track. Failure to follow this instruction may result in the failure of the seat to perform as designed with resultant risk of personal injury to the vehicle occupant.
CAUTION:
Do not overtighten or damage will occur.
NOTE:
When assembled, a small gap between one of the gears and the drive tube may exist.
CAUTION:
The seat track gear rack must be supported during installation of the roll pin.
