Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Torque wrench
- Clean rag
- Fluid pump (if adding fluid)

2. Check Fluid Level

Remove the fill plug from the transfer case.
Insert your finger into the fill hole to check fluid presence.
- If fluid is present and at the correct level, re-install the fill plug and tighten.
- If fluid is low or absent, note that additional fluid is required.

3. Add Fluid (if necessary)

If fluid is low, use the fluid pump to add the manufacturer-recommended transfer case fluid.
- Recommended fluid: Ford XL-12, or equivalent.
Fill until the fluid begins to seep from the fill hole.
Re-install the fill plug and torque it to the manufacturer’s specifications (typically around 18-25 lb-ft).

4. Clean Up

Wipe any spilled fluid with a clean rag.
Ensure the work area is clear of tools and debris.
