How to Change Your 4×4 Fluids

Now, I know what you’re thinking.

“Can’t I just take it to the shop?”

Sure, you could.

But where’s the fun in that?

Plus, doing it yourself can save you some serious coin.

Here’s a quick rundown of the process:

1. Gather your supplies (fluid, filter if needed, drain pan, funnel)
2. Locate the drain plug and remove it
3. Let the old fluid drain completely
4. Replace the drain plug
5. Fill with new fluid
6. Check the level and top off if necessary

Sounds simple, right?

Well, it is and it isn’t.

Each fluid has its quirks, and if you’re not careful, you could end up with a mess bigger than a bull in a china shop.

Tips for a Smooth Fluid Change

Here are some pearls of wisdom I’ve gathered over the years:

The Environmental Impact

Now, I know we off-roaders get a bad rap sometimes, but we can do our part for Mother Nature.

When changing your fluids, always dispose of the old stuff properly.

Your local auto parts store usually has a recycling program.

It’s a small step, but hey, every little bit helps keep our trails clean for future generations of mud-slingers.

Conclusion:

There you have it, folks – the ins and outs of 4×4 fluid changes.

It might not be the most glamorous part of off-roading, but it’s crucial if you want to keep your rig running like a well-oiled machine (pun absolutely intended).

Remember, a little preventive maintenance goes a long way in keeping your 4×4 ready for whatever the trail throws at you.

So, next time you’re out there conquering the great outdoors in your trusty 4×4, take a moment to appreciate all those hard-working fluids.

And maybe, just maybe, you’ll remember to change them on time.

Your wallet (and your mechanic) will thank you.

Stick to what your owner’s manual recommends or consult with the experts at 4WDG.
