Side Case Replacement
WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the rear differential (see REAR DIFFERENTIAL REMOVAL )
- Remove the rear differential front mounting brackets (A) from the rear differential (B)
- Disconnect the rear differential fluid temperature sensor 2P connector (A), then remove the rear differential fluid temperature sensor cover (B), the rear differential fluid temperature sensor (C), and the O-ring (D)
- Disconnect the left and right solenoid 4P connectors (A)
- Remove the ground cable bolt (B) and rear differential harness bracket D, then remove the rear differential subharness (C)
- Remove the rear differential left side case (A) or the rear differential right side case (D), and the 10x12 mm dowel pins (E) from the rear differential center case (F)
- Remove rear differential harness bracket B and rear differential harness bracket C
- Replace the rear differential left side case or the rear differential right side case
- Remove the ring gear (A), the needle bearing (B), and the 60.2 mm shim (C) from the differential side case (D)
- Measure the distance (1) between the end of the rear differential side case (A) and the 60.2 mm shim contact area (B) of the planetary gear with a straight edge (C) and a depth gauge (D) Measure at three locations, and average the reading
- Measure the distance (2) between the end of the rear differential center case (A) and the ring gear contact area (B) of the tapper roller bearing with a straight edge (C) and a depth gauge (D) Measure at three locations, and average the reading
- Measure the distance (3) between the needle bearing (A) and the tapper roller bearing contact area (B) of ring gear with a depth gauge (C) Measure at three locations, and average the readingNOTE:
- Carry out the measurement at normal room temperature
- Clean all parts thoroughly before measure
Shim Selection Formula
- Select the proper 60.2 mm shim from the table Follow the example below, and use the measurements you made in step 10 to 12
(Basic Formula)
(1) + (2) - ((3) + 0 19)= shim thickness
0.19 mm (0.007 in) middle of the standard clearance
Standard Clearance
0.14-0.24 mm (0.006-0.009 in)
(For example)
(1) = 6.12 mm (0.241 in)
(2) = 153 mm (0.602 in)
(3) = 19.56 mm (0.770 in)
6.12 + 15.3 - (19.56 + 0.19) = 1.67 mm
Select the 1.60 mm shim from the table
60.2 mm shim
PART THICKNESS CHARTNo Thickness A 1 10 mm (0 043 in) B 1 20 mm (0 047 in) C 1 30 mm (0 051 in) D 1 40 mm (0 055 in) E 1 50 mm (0 059 in) F 1 60 mm (0 063 in) G 1 70 mm (0 067 in) H 1 80 mm (0 071 in) I 1 90 mm (0 075 in) J 2 00 mm (0 079 in) K 2 10 mm (0 083 in) L 2 20 mm (0 087 in) - Place one strip of plastigage (A) on the 60.2 mm shim contact area (B) of planetary gear Install the 60.2 mm shim (C), the needle bearing (D), and the ring rear (E) Measure at three locations as shown.
- Install the 10x12 mm dowel pins (A), the rear differential right side case (B) or the rear differential left side case (C), and the mounting bolts (D) onto the rear differential center case (E)
- Tighten the mounting bolts in a crisscross pattern in several steps, then tighten the bolts to the specified torque
- Remove the rear differential left side case (A) or the rear differential right side case (B), and the 10 x 12 mm dowel pins (C) from the rear differential center case (D)
- Remove the ring gear (A), the needle bearing (B), and the 60 2 mm shim (C) from the differential side case (D)
- Measure the widest part of the plastigage Measure at three locations, and average the reading
- If the clearance exceeds the standard, go to step 9
- If the clearance is within the standard, go to step 20
Standard Clearance
0.14-0 24 mm (0.006-0.009 in)
- Install the 60.2 mm shim (A), the needle bearing (B), and the ring gear (C) onto the rear differential side case (D)
- Remove the dirt and oil from the sealing surfaces Apply liquid gasket (P/N 08717-0004,08718-0001, 08718-0003, or 08718-0009) to the sealing surface Make sure you seal up to the inside edge of the bolt holes to prevent oil leakageNOTE:
- You must assemble the housings within 5 minutes after applying the liquid gasket If you applied liquid gasket P/N 08718-0012, the component must be installed within 4 minutes If not, the sealing surface must be cleaned, and the liquid gasket reapplied
- Allow the liquid gasket to cure at least 30 minutes after assembly before filling the differential with fluid
Left side case/Right side case
- Install the 10 x 12 mm dowel pins (A), the rear differential right side case (D) or the rear differential left side case (E), and the mounting bolts (F) onto the rear differential center case (G)
- Install rear differential harness bracket B and rear differential harness bracket C
- Tighten the mounting bolts in a crisscross pattern in several steps, then tighten the bolts to the specified torque
- Install the rear differential subharness (A) and rear differential harness bracket D, and install the ground cable (B)
- Connect the left and right solenoid 4P connectors (C)
- Install the rear differential fluid temperature sensor (A) with a new O-ring (B), and install the rear differential fluid temperature sensor cover (C)
- Connect the rear differential fluid temperature sensor 2P connector (D)
- Install the rear differential front mounting brackets (A) with new bolts (B) on the rear differential (C)
- Install the rear differential (see REAR DIFFERENTIAL INSTALLATION )
- Do the SH-AWD differential clutch torque memorization (see SH-AWD DIFFERENTIAL CLUTCH TORQUE MEMORIZATION )
