Intermediate Shaft Seal and Deflector: Installation
WARNING: This page is about a different variant/trim than selected.
NOTE:
The following illustration shows the correct orientation of the seal components when installed in the vehicle.
| Item | Part Number | Description |
|---|---|---|
| 1 | - | Intermediate shaft seal (part of 7275 kit) |
| 2 | - | Alignment washer (part of 7275 kit) |
| 3 | - | Seal deflector (part of 7275 kit) |
- Place the intermediate shaft seal on the PTU Link shaft Seal Installer and Driver Handle with the spring side facing away from the tool.
- Using the PTU Link shaft Seal Installer and Driver Handle, install the intermediate shaft seal.
- Place the alignment washer on the PTU Link shaft Seal Installer and Driver Handle with the beveled edge (white-striped side) facing towards the tool.
- Using the PTU Link shaft Seal Installer and Driver Handle, install the alignment washer by hand, pushing it in until it bottoms against the seal.
- When installed, the white-striped side should be facing out.
- Position the deflector on the PTU Link shaft Seal Dust Shield Installer using silicone brake caliper grease and dielectric compound to retain it to the installer. Using a suitable heat gun, heat the deflector to a minimum of 66°C (150°F) and a maximum of 100°C (212°F) by concentrating the heat across the back of the installer while rotating, not directly on the deflector itself.
- As an alternative method to heating the seal deflector, place the deflector in boiling water for 3 to 5 minutes. Dry off the deflector and install.
- Install the seal deflector immediately after heating using the PTU Link shaft Seal Dust Shield Installer and Driver Handle.
- Make sure the deflector is completely seated all the way around and there are no cracks on the face or inner diameter white-colored tab. The deflector is correctly installed when the face of the deflector is recessed 3-5 mm (0.12-0.20 in) into the pocket all the way around.
- Using brake parts cleaner, thoroughly clean the deflector and intermediate shaft area of any residual fluid that may have accumulated during the repair.
- Install the intermediate shaft. For additional information, refer to FRONT DRIVE HALFSHAFTS article.
- Top off the transmission fluid as necessary.
NOTE:
Do not use force when installing the alignment washer or damage to the washer can occur.
NOTE:
Do not overheat (melt) the seal deflector. Monitor the temperature of the deflector with a suitable temperature measuring device, such as a digital temperature laser or infrared thermometer, while heating. Do not allow the temperature to exceed 100°C (212°F). Overheating will damage the deflector. If the deflector is damaged, a new deflector must be used.
NOTE:
Apply a small amount of silicone brake caliper grease and dielectric compound to the inner lip of the deflector where it installs on the tube inside the PTU before heating. This will ease the installation of the deflector.

NOTE:
Some residual fluid will collect between the seal and deflector during this repair. This is a normal condition and should not be misinterpreted as a leak after the repair is complete.
