I did this weeks ago. All went fine. This is a super easy job. Most importantly got the job right 100% and saved at least $500!
NOTE: Illustration purposes only
Rear axle seal: 90310-50006 ($ 8.00): USE OEM TOYOTA ONLY.
O Ring: 90301-88077 ($ 4.00)
Tools required: 10 and 14 mm, hammer, seal driver
1) Put the truck on jack stands and slide the removed wheels under the truck. Shake the truck to see everything is solid before you crawl under the truck.
2) Remove the park brake cable lock-clip (pic-1).
3) Clean the threads with a wire brush and remove the four 14 mm bolts holding the axle shaft to the axle housing (pic-2), BUT don’t pull the shaft out.
4) Disconnect the brake hose and attach a windshield washer hose to the steel brake line and cap the other end of the windshield washer hose with a bolt (Pic-3)
5) Place a pan to collect oil and pull the axle shaft out (no need to remove the brake shoes and its hardware). Check the threads of the studs. If damaged, part number for studs: 90114-10002 (Pictures 4, 5, 6)
6) Measure the distance to the oil seal to the axle-shaft mating surface: I had 37 mm (Pic-7). This may come handy when you want to make sure you installed the seal at the right depth. [The seal has 8 mm thickness and the space to hold the seal is also 8 mm, Pic-8)]
7) Keep the oil seals in a freezer OVER-NIGHT.
8) Apply a small film of oil on the metal surface of the seal. Clean the axle housing surface and place the oil seal in place. I pressed in and hold the 9 O’clock position and with the flat end of the seal driver, I gently hit the 2 and 4 O’clock positions. Now the seal is in place (pic-9, 10).
9) After making sure the seal is lining up with the shaft bore (use a caliper and measure the depth on several locations: (pic 11, 12), use the seal driver and drive in the seal to its location (pic-13). Again, use the caliper and find whether it is straight in the shaft. You will get 37.5 mm depth for the seal to the grove on the axle housing mating surface.
10) Clean the mating surfaces of axle shaft and axle housing, and then install the O-ring (Pic-14). Gently slide the axle shaft into the housing: IMPORTANT: don’t let the shaft to rest on the oil seal.
11) Quickly remove the rubber hose attached to the brake line and slide the 4 studs into the housing and attach the brake hose to the wheel cylinder.
12) Torque the 14 mm bolts to 50 ft-lb’s:
