How to Get Your 4×4 Ready for Spring

Scott Carline • April 8, 2022

It doesn’t matter if your 4×4 has been holed up in the garage all weekend or you’ve been out enjoying the frosty trails – spring weather is finally here! Your vehicle is an investment, and it’s essential to keep it well-maintained after every season of driving so you’re not stuck on the side of the trail when you go offroading this year. Check out the spring maintenance tips for your 4X4 below! 

Start With a Thorough Cleaning

Whether you’re a DIY car washer or have it detailed by a professional, you can’t skip this step before going back on the road. Snow and freezing winter weather means salt, and that means residue that can damage the underside and body of your 4×4. Ensure your exterior cleaning job is comprehensive enough to get rid of that residue; it can eat away at the paint and eventually lead to corrosion. 

Don’t miss washing the undercarriage with a high-pressure hose. If your fenders are messy and gunked up, consider upgrading to a set of off-road fenders for your 4×4. When you’re done cleaning off the mess, head to your headlights. Well-lit trails and roadways are vital to staying safe, and if you can’t get your headlights clean to allow the light entirely through, it’s time for a replacement or even an upgrade to LED lights.

Time for a Check-Up

Now that your 4×4 vehicle is thoroughly clean, it’s time to get down to the nuts and bolts of maintenance. 

Undercarriage: Check for loose parts, hoses, damage, frayed wires, or anything else that could lead to severe problems when you’re out on an adventure. Tighten any bolts on gear, and make notes for when you bring in your Jeep for any modifications or repairs.

Exterior parts: When you’re offroading in the mud, rain, or heavy wind, make sure you’re protected from the elements. Replace your wiper blades, check plastic windows, and replace broken or old parts. It will help keep you safer and less exposed and could prevent serious problems on the trail. 

Battery: Check that your 4×4’s battery is fully charged, properly attached, and free of corrosion. Ensure that your jumper cables work, and even think about picking up an extra battery to have on hand when you’re on the road. 

Belts and hoses: These are essential parts of keeping your 4×4 running smoothly. When belts and hoses aren’t working correctly or worn down, you’re at risk of breaking down or even ruining your engine altogether. 

Tires and brakes : Between climbing and stopping, traction is a big deal when it comes to keeping your 4×4 safe and in top shape. Tires should have plenty of tread, and brake pads need to be thick enough to help you stop safely.

Oil and other fluids: This is a great time to change your oil, regardless of what your odometer says. Make sure you also replace the oil filter to keep things running well through spring. Top off wiper fluid, coolant, power steering, and brake fluids while you’re at it.

 

Talk to Us About Mods

Spring is a great time to make an appointment to upgrade your 4×4 with custom modifications to enjoy sunny spring and summer offroading.

  • Backup cameras are a great feature for new drivers or those new to driving a 4×4, especially if it’s modified to be larger, longer, or taller than the factory model. They allow drivers to see what’s behind them and come in handy during inclement weather. Wiring can be tricky for this modification, so experienced professionals should do it.
  • Factory latches are generally made out of stretchy rubber, and while it’s unlikely that your hood will fly off on the highway, the movement at faster speeds may seem problematic. Upgrading your latches will give you peace of mind and even more security to protect any expensive aftermarket upgrades under the hood.
  • If you only choose one modification, let it be a recovery winch — especially if you’re interested in using your 4×4 for offroading. Winches are the only way to get your vehicle out of a ditch or other tricky spots. Having one can be particularly handy if you’re offroading with friends and they get stuck.
  • Think beyond size and width when choosing something different from the factory tires that came with your 4×4. Unless you plan to use your vehicle strictly for road driving, it’s wise to select a set of all-terrain (A/T) tires that adapt traction to your driving surface.

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.
