    Torque:
    15 N*m{155 kgf*cm, 11 ft.*lbf}
    NOTICE:
    Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench (YARIS_NCP93 RM000000UYX0BYX.html).


6. INSTALL REAR RH FLEXIBLE HOSE
HINT:
The installation procedure for the RH side is the same as that for the LH side.

    RH Side
    *b
    LH Side
    Length of shock absorber:
    220 mm (8.66 in.)
  1. Fully tighten the 2 bolts.

    Torque:
    90 N*m{918 kgf*cm, 67 ft.*lbf}


11. FULLY TIGHTEN REAR SHOCK ABSORBER LH
  1. Fully tighten the shock absorber (lower side) with the bolt.

    Torque:
    49 N*m{500 kgf*cm, 36 ft.*lbf}


12. FULLY TIGHTEN REAR SHOCK ABSORBER RH
HINT:
The installation procedure for the RH side is the same as that for the LH side.


13. INSTALL REAR SEATBACK ASSEMBLY (for Fixed Seat Type)


Yaris. Ncp93, 131.Rear Suspension.Rear Suspension System (For Sedan).Rear Coil Spring (For Sedan)  Installation
  1. Remove the rear seat outer belt from the rear seat shoulder belt guide.

    HINT:
    Use the same procedure for both sides.
  1. Remove the rear center seat outer belt from the rear center seat shoulder belt guide.



    Yaris. Ncp93, 131
  1. Remove the 3 bolts.

  1. Disengage the 3 hooks and remove the rear seatback.



14. INSTALL REAR SEAT CUSHION COVER PAD SUB-ASSEMBLY (for Fixed Seat Type)
