Inspection [06/2015 - ]: Procedure

2016 Scion iM Automatic CVT TransSECTION Procedure
WARNING: This page is about a different variant/trim than selected.
  1. INSPECT FRONT DIFFERENTIAL CASE ASSEMBLY WITH RING GEAR 
    1. Using SST, rotate the front differential side gear as shown in the illustration.
      • SST: 09528-52010 
        1. 09528-05040

      Standard

      The front differential side gear does not lock when rotated in either direction.

      • If the front differential side gear locks, perform all of the following inspections.
      • If the front differential side gear still locks after replacing the malfunctioning parts, replace the front differential case assembly with ring gear.
  2. INSPECT FRONT DIFFERENTIAL SIDE GEAR THRUST AMOUNT 
    1. Secure the front differential case assembly with ring gear in a vise between aluminum plates.
      NOTE:

      Do not overtighten the vise.

    2. Using SST and a dial indicator, measure the front differential side gear thrust amount.
      • SST: 09528-52010 
        1. 09528-05040

      *a Front Differential Side Gear Thrust Amount

      Front Differential Side Gear Thrust Amount

      0.08 mm (0.00315 in.) or less

      HINT: 

      • Measure the front differential side gear thrust amount while slowly rotating the front differential side gear.
      • Make sure to measure the front differential side gear thrust amount for both of the front differential side gears.

      If the result is not as specified, replace the front differential side gears, front differential pinions and conical springs.

  3. INSPECT FRONT DIFFERENTIAL PINION BACKLASH 
    1. Install SST as shown in the illustration and tighten it.

      *a Turn *b Hold
      • SST: 09528-52010 
        1. 09953-05010
        2. 09528-05020

      Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) 

    2. Secure the front differential case assembly with ring gear in a vise between aluminum plates.
      NOTE:

      Do not overtighten the vise.

    3. Install the front No. 1 differential pinion shaft to the front differential pinion as shown in the illustration.

      *1 Front No. 1 Differential Pinion Shaft
    4. Using a dial indicator, measure the front differential pinion backlash.

      Standard Backlash

      0.20 mm (0.00787 in.) or less

      If the backlash is not as specified, replace the front No. 1 differential side gear thrust washers with washers of a different thickness. Use the table below to select a front No. 1 differential side gear thrust washer which will ensure that the backlash is within the specification.

      HINT: 

      Select front No. 1 differential side gear thrust washers of the same thickness for both the right and left side.

      Front No. 1 Differential Side Gear Thrust Washer Thickness

      Mark Thickness mm (in.)
      14 0.95 (0.0374)
      02 1.00 (0.0394)
      15 1.05 (0.0413)
      03 1.10 (0.0433)
      16 1.15 (0.0453)
      04 1.20 (0.0472)
  4. INSPECT FRONT DIFFERENTIAL PINION THRUST WASHER 
    1. Using a micrometer, measure the thickness of the front differential pinion thrust washer.

      Minimum Thickness

      0.92 mm (0.0362 in.)

      HINT: 

      Measure the most worn portion of the front differential pinion thrust washer.

      If the thickness is less than the minimum, replace the front differential pinion thrust washer.

  5. INSPECT FRONT NO. 1 DIFFERENTIAL PINION SHAFT 
    1. Using a micrometer, measure the outer diameter of the front No. 1 differential pinion shaft.

      Minimum Outer Diameter

      16.982 mm (0.669 in.)

      HINT: 

      Measure the most worn portion of the front No. 1 differential pinion shaft.

      If the outer diameter is less than the minimum, replace the front No. 1 differential pinion shaft.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
