- Gloves
- Safety glasses
By ensuring we have these items at hand, we’re all set to navigate the fluid change like pros.
The last thing we need to check is the specific type of fluid recommended by our vehicle’s manufacturer. Transfer case fluid types vary, and using the wrong one could lead to suboptimal performance or even damage. Interestingly, some modern vehicles use automatic transmission fluid, while others may call for specialized gear oils or synthetic fluids.
Fluid Level Check
Once we’ve taken care of the listed precautions, we’re ready to begin. It’s crucial to monitor the fluid level as we proceed with the maintenance routine. Maintaining the right level will keep our transfer case running effortlessly, which in turn ensures that our adventures off the beaten path are as exhilarating as they should be.
Steps to change transfer case fluid
Maintaining your vehicle’s four-wheel drive system is critical, and changing the transfer case fluid is a part of regular upkeep we can’t ignore. With the right tools and a bit of time, it’s a task we can handle ourselves. Here’s how we can go about it:
Firstly, gather all necessary tools and materials. We’ll need:
- A suitable catch pan to collect the old fluid
- A set of socket wrenches
- A torque wrench
- A new gasket or RTV sealant, if required
- The manufacturer-recommended transfer case fluid
- A funnel and a fluid pump for an easy refill
Once we have all that we need, let’s start the process:
Step 1: Draining the Old Fluid
Find the transfer case drain plug, which is generally located at the lowest point. Place the catch pan under the plug, remove it with a socket wrench, and let the old fluid drain completely. It’s best to wait a few minutes to ensure all fluid has drained out.
