Question 1

How to replace the Differential Seal in a rear differential on Toyota Land Cruiser?

Accepted Answer

The process to disconnect and replace rear differential seals and gaskets begins with marking the propeller shaft and companion flange for alignment then unfastening the 4 nuts, bolts and washers before properly supporting the shaft when it comes loose. First use Special Service Tool: 09330-00021 to hold the flange while unstaking the nut with a chisel and hammer until removal. Then use Special Service Tool: 09950-30011 together with 09951-03010, 09953-03010, 09954-03010, 09955-03030, and 09956-03040 tools to extract the flange. Afterward drain all hypoid gear oil. Special Service Tool: 09308-10010 enables the removal of the oil seal followed by the oil slinger and the front bearing removal procedure is completed with Special Service Tool: 09556-22010. Use Special Service Tool: 09308-00010 to remove the bearing outer race while carefully protecting the taper surface and after that remove the bearing spacer. Use Special Service Tools: 09318-60011 (09316-00011, 09316-00021) together with a hammer to install the bearing spacer before installing the bearing outer race. The repair procedure involves applying hypoid gear oil on the periphery of the new oil seal before installation with Special Service Tool: 09214-76011 and a hammer to achieve a depth of 0.5 mm (0.020 inch). After oil seal installation, coat its lip with MP grease. To install the drive pinion flange secure its threads with gear oil then tighten it to 245 Nm (2,500 kgf-cm, 181 ft. lbs.) while stabilizing the part with Special Service Tool: 09330-00021. Reconnect the rear propeller shaft using the drive pinion preload adjustment followed by drive pinion nut staking then bolt the 4 components along with their washers and nuts with 106 Nm (1,080 kgf-cm, 78 ft. lbs.) torque while matching marks. The last step requires filling the differential with hypoid gear oil but only API GL-5 without LSD or hypoid gear oil LSD API GL-5 with LSD. The oil viscosity should match SAE 90 above -18 degrees Celsius (0 degrees Fahrenheit) or SAE 80W-90 or 80W below -18 degrees Celsius (0 degrees Fahrenheit). The differential capacity is 3.20 liters (3.38 US qts, 2.82 Imp.qts) with differential lock or 3.30 liters (3.49 US qts, 2.90 Imp.qts) for others.

Question 2

How to replace a Differential Seal in the front of a U151F on Toyota Sienna?

Accepted Answer

The front differential oil seal replacement (U151F) starts with front wheel removal and Engine Under Cover No.1 detachment along with automatic transaxle fluid draining through drain plug removal followed by gasket replacement and plug torque direction of 49 Nm (500 kgf-cm, 36 ft.lbs.). The differential side bearing retainer oil seal replacement process starts with removal of both the front drive shaft assembly LH and Special Service Tool: 09308-00010. Add new oil seal through Special Service Tools: 09223-15020 and 09950-70010 (09951-07150) followed by hammering the seal to reach a depth of 0 + 0.5 mm (0 + 0.020 inch) before coating its lip with MP grease. Install the front drive shaft assembly LH together with engine under cover No.1 and front wheel by applying torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.). The technician needs to check the automatic transaxle fluid while inspecting its condition along with verifying front wheel alignment and ABS speed sensor signals. The necessary procedure for additional disassembly includes removing both engine assembly with transaxle and front drive shaft assemblies LH and RH together with the transfer stiffener plate RH and automatic transmission with transfer and transfer assembly. Before installing the new oil seal with Special Service Tool: 09649-17010, 09950-70010 (09951-07200) to 6.0 plus or minus 0.5 mm (0.236 plus or minus 0.020 inch) depth apply MP grease on the seal's lip. The service procedure ends with the installation of the front drive shaft assemblies RH and LH along with the transfer assembly and automatic transmission with transfer and transfer stiffener plate RH using Special Service Tool: 09670-00010.

Question 3

How to Replace the Differential Seal in a Rear Differential on Toyota Sequoia?

Accepted Answer

You should start the replacement by draining formal differential oil and disconnecting the rear propeller shaft. The companion flange nut removal for 2WD requires loosening the staked part through chiseling with a hammer followed by adding 3 stud bolts with 40 mm (1.57 inch) head extensions. The installation of 3 companion flange nuts requires Special Service Tool: 09213-58013 while tool 09330-00021 holds the companion flange to remove the nut. For 4WD operations first loosen the staked part of the nut and apply Special Service Tool: 09330-00021 to hold the flange before extracting the nut. You can remove the companion flange using Special Service Tool: 09950-30012 (09951-03010, 09953-03010, 09954-03010, 09955-03030, 09956-03050). Finally, use Special Service Tool: 09308-10010 to remove the oil seal. Use Special Service Tool 09556-22010 to eliminate the front bearing after which extract the two washers and the bearing spacer. Place the front bearing as you simultaneously apply Special Service Tool: 09950-30012 (09951-03010, 09953-03010, 09954-03010, 09955-03030, 09956-03050) that goes with the companion flange to install the bearing before removing the flange. The installation of the new oil seal requires MP grease on its lip as Special Service Tools 09316-12010 and 09649-17010 along with a plastic hammer to achieve proper fitment to the differential carrier end while keeping the tools secured together with vinyl tape. When installing the companion flange to the drive pinion position the threads of a new nut with hypoid gear oil. The 2WD installation requires using three stud bolts to extend the head 40 mm (1.57 inch) before setting Special Service Tool: 09213-58013 and applying three nuts to the companion flange. Use tool Special Service Tool: 09330-00021 to secure the companion flange while torquing the nut to 147 Nm (1,500 kgf-cm, 109 ft. lbs.) before removing the nuts and stud bolts and the tool. The technician must utilize Special Service Tool: 09330-00021 to secure the companion flange while torquing the nut to 147 Nm (1,500 kgf-cm, 109 ft. lbs.) for 4WD. After adjusting drive pinion preload you must stake the drive pinion nut while reattaching the rear propeller shaft then fill the differential with hypoid gear oil to a torquing value of 49 Nm (500 kgf-cm, 36 ft. lbs.) using hypoid gear oil API GL-5 with a specified viscosity of SAE 75W-140 (Synthetic) requiring a 3.65 liters (3.86 US qts, 3.21 Imp. qts) volume.
