Toyota 90311-50031 Type T Oil Seal

Fluid leaks frequently occur due to wear of the drive axle oil seals or speed sensor O-rings, with replacement being relatively easy as repairs can usually be performed without removing the transaxle from the vehicle. The drive axle oil seals are located on each side of the transaxle, where the drive axle shaft is splined into the differential. If leakage at the seal is suspected, raise the vehicle and support it securely on jack stands; fluid will be found on the side of the transaxle if the seal is leaking. Remove the drive axle assembly, and if replacing the right side drive axle seal, remove the intermediate shaft and the drive axle assembly as a single unit. Carefully pry the oil seal out of the transaxle bore using a screwdriver or pry bar, ensuring not to gouge or nick the surface of the seal bore. If the oil seal cannot be removed with these tools, a special oil seal removal tool will be required. To install the new oil seal, use a large section of pipe or a large deep socket as a drift, driving it into the bore squarely and ensuring it is completely seated, while lubricating the lip of the new seal with multi-purpose grease. After installation, be careful not to damage the lip of the new seal when reinstalling the drive axle assembly. The direct clutch speed sensor seal for 2001 through 2003 models is located on the transaxle housing; check for lubricant around the sensor housing to determine if the O-ring is leaking. Disconnect the electrical connector from the direct clutch speed sensor and remove the sensor from the transaxle, then remove the O-ring. Finally, install a new O-ring on the sensor body and reinstall the direct clutch speed sensor, tightening the hold-down bolt securely.
