AXLE AND DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY: REASSEMBLY; 2013 MY FR-S [03/2012 -] (Continued)

25. INSPECT TOTAL PRELOAD

(a) Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.





Total Preload (at Starting):





If the total preload is not within the specified range, adjust the total preload or perform repairs as necessary.

26. INSPECT DIFFERENTIAL RING GEAR BACKLASH

(a) Set a dial indicator perpendicular to the end of the differential ring gear face.

(b) While holding the rear drive pinion companion flange, rotate the differential ring gear and measure the backlash.





Standard Backlash:

0.13 to 0.18 mm (0.00512 to 0.00708 in.)

27. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY

(a) Using a dial indicator, measure the vertical and lateral runout of the rear drive pinion companion flange.









Maximum Runout:





NOTICE:
Measure the runout of the rear drive pinion companion flange horizontally at a position 30 mm (1.181 in.) away from the center of the differential drive pinion shaft.

If the runout is more than the maximum, replace the rear drive pinion companion flange and differential ring gear.

28. STAKE REAR DRIVE PINION NUT

(a) Using SST and a hammer, stake the rear drive pinion nut.





SST : 09930-00010

29. INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT OIL SEAL Replacement

30. INSTALL REAR DIFFERENTIAL DRAIN PLUG

(a) Using a hexagon wrench 10 mm, install the rear differential drain plug and a new gasket.

Torque : 49 Nm (500 kgf-cm, 36 ft-lbf)

31. REMOVE REAR DIFFERENTIAL CARRIER SUB-ASSEMBLY

(a) Remove the rear differential carrier sub-assembly from the overhaul stand.





32. INSTALL REAR DIFFERENTIAL BREATHER PLUG OIL DEFLECTOR

(a) Clean the seal packing attached to the rear differential carrier and the rear differential carrier cover using a scraper and wire brush. Then, remove the oil with a non-residue solvent or equivalent.

NOTICE:
Do not scratch the sealing surface.

(b) Install the rear differential breather plug oil deflector to the rear differential carrier cover with the bolt.





Torque : 8.0 Nm (82 kgf-cm, 71 in-lbf)

33. INSTALL REAR DIFFERENTIAL CARRIER COVER

(a) Apply seal packing to the rear differential carrier cover as shown in the illustration.









Seal packing:

Toyota Genuine Seal Packing 1281, Three Bond 1281 or equivalent

NOTICE:
* Apply the seal packing in a continuous line, approximately 2 to 3 mm (0.0787 to 0.118 in.) in diameter.
* Overlap the seal packing at least 10 mm (0.394 in.) at the beginning and end of application.
* Install the rear differential carrier cover within 3 minutes of application.

(b) Install the rear differential carrier cover with the 8 bolts.





Torque : 47 Nm (479 kgf-cm, 35 ft-lbf)

NOTICE:
Do not fill the differential with oil or drive the vehicle immediately after installing the differential carrier cover. Leave the vehicle for at least 1 hour. Also, avoid sudden acceleration and deceleration for at least 12 hours after application.

34. INSTALL REAR DIFFERENTIAL BREATHER PLUG

(a) Install the rear differential breather plug to the rear differential carrier cover.





Torque : 21 Nm (214 kgf-cm, 15 ft-lbf)
