Warranty Information

Applicable Warranty*:
This repair is covered under the Toyota Comprehensive Warranty. This warranty is in effect for 36 months or 36,000 miles, whichever occurs first, from the vehicle's in-service date.

* Warranty application is limited to correction of a problem based upon a customer's specific complaint.

Repair Procedure

For reference refer to the Technical Information System (TIS), applicable model year 4 Runner Repair Manual: Exterior/Interior Trim: Roof Headlining Assy: Replacement.







1. Check passenger side second row seat back latch to striker alignment.

2. Determine if the striker is centered in the seat back latch by slowly moving the passenger side second seat back toward the striker. Visually check to see if the striker is centered in the seat back latch.

Wear marks on the top or bottom portion of the striker indicate a possible misalignment issue. If wear marks are found to be on top of the striker, the striker must be adjusted downward to remedy the condition and vice versa.

3. If striker misalignment is detected, continue with step 4.

If the striker is found to be centered in the seat latch and there are NO wear marks evident on the top or bottom surfaces of the striker, the following field fix will NOT be effective.

4. Remove the passenger side second row seat back striker and elongate the bottom mounting hole to allow striker adjustment.

(For necessary interior disassembly instructions to access the second row seat back striker, refer to TIS, applicable model year 4Runner Repair Manual: Exterior/interior Trim: Roof Headlining Assy: Replacement: steps 1 - 23).

A. Remove the three bolts that secure the second row seat back latch striker to the vehicle body.









B. Remove 1 mm of striker plate material from the top and bottom of the bottom striker plate bolt hole to elongate the hole and create striker adjustability as shown in the illustration.

5. Reinstall striker to vehicle body and adjust striker to center of seat latch.

A. Install the passenger side second row seat back striker by threading each of the three (3) bolts into the body. Do NOT tighten the three (3) bolts at this time.









B. Rotate the seat back toward the striker and align the striker in the center of the seat back latch.

C. Tighten the three (3) bolts to secure the striker in place.

6. Reassemble the vehicle interior in reverse order of disassembly.
