Basic 4×4 Maintenance

Scott Carline • December 13, 2021

Have a new 4X4 that’s still under warranty? Congratulations – there’s not much you have to do on your own to keep up with the basic 4×4 maintenance other than quick visual checks (see below). This blog post isn’t for you quite yet, but it’s important to read and bookmark. Put a few miles and years on your 4X4 you’ll want to know the ins and outs of preventative maintenance.

The best place to start is with your vehicle’s owner manual. Who better than the vehicle’s manufacturer to tell you how to care for it? Even if you’re not one to love following the rules, the owner’s manual is a great way to best understand what you can be doing to take care of your 4X4. Plan out a maintenance schedule and even though you may be tempted, don’t wait longer than recommended in between service appointments. 

Much of this you can do on your own, starting with visual checks that can be performed as often as every time you drive your 4X4:

  • Fluid levels: Oil, wiper and transmission fluids, brake fluid, power steering, coolant – these are all fluids that are crucial for keeping your 4X4 on the road. 
  • Tires & batteries: Test the air pressure in tires and the tread for wear. Pop the hood and look at the battery connectors; if there is rust or corrosion you need to do some light cleaning.
  • Radiator and Hoses: Leaks and cracks can cause serious havoc under the hood, so look closely for those as you perform your visual check.
  • Brakes: This is a little more complex of a job and should really be tackled by a mechanic but you will know when your brakes need to be repaired when you drive your 4X4.

These visual checks will alert you to any small issue with your vehicle, and the regular services listed below will also alert mechanics to any need for repairs:

  • Oil & filter change: The frequency of this service depends on the make and model of your car and the type of oil you use. You could try this on your own if you’re comfortable with the task, but just make sure to replace the oil filter as well.
  • Fuel filter change: Your fuel filter keeps the “guts” of your car clean and you need to change it frequently to maintain the performance of your 4X4. This is generally included in services that mechanics offer.
  • Tire rotation: This is another simple service but also one that should be performed by someone who has the skills and experience to do it quickly and safely, but it’s a regular service that goes a long way towards extending the life of your tires and the overall performance of the vehicle.

Don’t overlook the importance of checking any mods you may have on your 4X4 as well. Mechanical issues with mods like winches or suspension, for example, can become a huge safety concern and grow into serious issues later on down the road.

Ultimately, it’s best to talk to an experienced mechanic about the type of preventative 4×4 maintenance schedule you can create for your vehicle.

So we're back inside at Axleboy Offroad. We've got our 2020 Jeep Gladiator Sport S. This is still bone stock. I haven't made any modifications to it yet. We have ordered and been receiving a lot of the components from our supplier partner. They're going to end up on this Jeep Gladiator. One thing that's going to be probably the most dramatic cosmetically and performance and everything else from the outside, is the lift kit, and the wheels, and the suspension. Yeah. So right now behind us is bone stock. Let's talk about suspension first. Why don't you tell us what we have here from TeraFlex? Sure. So from TeraFlex, we're doing the adjustable alpine IR arms. IR stands for independent rotation. Now this is a really new product and it's amazing in the fact that it uses the bushing, so we're going to retain the same sound dampening and the same ride quality as we would when we're stock. But the inner sleeve that the bolt actually goes on... Okay. This is actually on a bearing. Okay. And it's a sealed bearing and unlike standard bushings where once the bolt clamps down, it's captive in the rubber and the rubber has to flex in order for this arm to move through its travel. The independent rotation allows free movement, no binding whatsoever, and this is huge in terms of ride quality, in terms of flex when you're off road or when you're on the RTI ramp at a Jeep show, or whatever it may be. We get the best of both worlds. We get the reliability of a good rubber bushing. We get the flexibility of a flex joint, but we don't have the parts that wear out or they get loose and make noise like the flex joints do. So it's kind of the best of both worlds. We expect that these bushings are going to last the vehicle's lifetime. This is a new product, this independent rotation bushing, been in testing and development for quite a while. We expect these to do amazing. What does installing an adjustable control arm do? What's the benefit for me as the Gladiator? Yeah, that's a great question. So we're going to lift it and we're going to raise the suspension. And the way that the geometry works, as we raise, this control arm is going to drop down further away. Now if you notice when this control arm swings down, it moves back. We actually lose some wheelbase when we lift it and it's just the nature of basic geometry. There's nothing we can do about that unless we put in an adjustable control arm. In this case, we can extend the length of this. We can recover our wheelbase, we can recover our alignment angles and our pinion angles as needed. So this gives us the ability to affectively adjust the front axle forward and backward. So we can make sure that the front axle is exactly where we want it. Exactly where we want it with the correct angle and the correct rotation. This is going to make the vehicle drive amazing. We're going to be able to keep caster where we want it, which is important because as we lift it caster drops out. Caster is the alignment angle that gives us stability going down the highway. We can roll it back in. Terrific. What else do we have here from TeraFlex? Well, we also have the new Falcon series three shocks. These are the brand new SP two shocks. Now I know in the past you and I have talked about how nice the Falcon shocks are because we have the quick adjust knobs. So we can turn this knob and we can go from soft ride to firm ride or tow, or if you're particularly picky like I know you are, you can go into setting number two, which gives you micro adjust on the small knob. You can literally dial in the ride as you drive. Now the SP two adds a new feature to it. Okay? It allows us to control the dampening, so this isn't as quick adjust or as easy, but what we can do, if you come in and say, "Dude, I am going to run down a gravel road and I'm going to run this thing hard." You can take the shock off and you can twist it, turn the bottom, and it goes into performance mode. Now this isn't going to be something you're changing in and out of every day. It's something you're probably going to do on install, but it gives you the ability to take the entire shock range and move it to more of a performance setting or to move it more to a comfort setting. Okay. So it just adds one more layer of adjustability to these shocks. These shocks are made up in Utah at the TeraFlex plant in the Falcon plant, handmade up there. Everything is amazing. We've been up on this line. It's the most spotless incredible thing you've ever seen. They've put a lot of time and development into this and these are definitely the best riding shock out there for the JK, and JL, and Gladiators. And it's going to look really cool. Oh yeah. How do you go wrong with all the big, all the billet, all the anodizing, the badging? They cut no corners on this thing at all. So I'm going to guess we've got a front and a back. Yeah. Yeah. So this will be the back. And so the importance with the back is... So it's a gladiator, right? So we're probably going to load it up with stuff, right? I mean, bicycles, kayaks, tent. So we're going to be taking weight in and out of it all the time. And that's really where the quick adjust knob is going to come in for us. So as you add that weight, all your shock dampening needs to change. It's easy now. Reach in there through the wheel-well, make a flip, and go. Going down the road or as a daily driver, what setting would I want to put it on? Well, I'll let you have it as far as a personal preference, but I know when I'm going down the road, just genuinely driving down the highway, I like a softer setting. I don't need to really feel the road. When we go to the firm settings, you're going to feel more input from the road. Now that's going to be great in certain situations. So if you're particularly driving sporty or driving heavy, you're going to want to have that road feel where you can feel the bumps and know what the vehicle is doing. With that, we're going to get a lot of roll control. So the vehicle is going to corner better and it will be able to handle the washboard gravel roads. Because I know like when you're out camping, you're driving down the- Gravel road. Yeah, yeah. You know how it is. You hit the bump and you bounce off the road, not with these, you move it to a firm setting and yeah, it's going to feel like you're zipping across the desert in a Baja race there. So really good stuff. Very adjustable, tunable to how you want it. So typically when you're off road or you're driving in let's say a spirited fashion, if you will, we're going to put them on firm. That's great. Well, thanks a lot to TeraFlex and to Axleboy Offroad. To learn more, you go to teraflex.com or visit us at axleboy.com.
