Verify which rear seat exhibits the condition. In the Repair Order, document which seat, along with the seat track position for/aft, where the noise occurred. Also verify whether both seat tracks are locked in by wiggling/pushing/puling the seat back. Observe and document in the Repair Order whether the seat jumps/skips when releasing the towel bar to slide the seat for/aft. Pictures above are examples of areas to evaluate. You may find other affected areas as well. 2. Loosen the affected right and/or left rear seat bolts. Refer to Rear Seat Removal and Installation in SI. • Adjust the seat to full rearward position. • Loosen the outboard front attachment bolt to un-clamp the joint, then the inboard bolt. • Adjust the seat to full forward position. • Ensure that both seat tracks are locked. • Loosen the outboard front attachment bolt to un-clamp the joint, then the inboard bolt. 3. While front and rear bolts are loose, with the seat in the full forward position, pull/push on the inboard and outboard corners of the cushion to ensure inboard and outboard tracks are locked in. 4. Tighten the rear seat bolts. Refer to Rear Seat Removal and Installation in SI. • Ensure seat is in full forward position. • Ensure both seat tracks are locked evenly in place and synchronized. • Tighten the rear inboard bolt to specified torque. 45 N*m (33 lbft) • Tighten the rear outboard bolt to specified torque. 45 N*m (33 lbft) • Adjust the seat to full rearward position. • Ensure both seat tracks are locked evenly in place and synchronized. • Tighten the front inboard bolt to specified torque. 45 N*m (33 lbft) • Tighten the front outboard bolt to specified torque. 45 N*m (33 lbft) 5. Check that the seat is not out of sync by sliding the seat forward (not to full forward) and lift/release towel bar. Confirm that either corners of the cushion are not jumping/skipping. If the seat jumps/skips, repeat steps 1–4. If there is no jumping/skipping, proceed to step 6. 6. Verify noise has been eliminated. If noise persists, replace the affected rear seat track, following the previously noted torque sequence procedure. Parts Information No parts are required for this repair.
