DIY Maintenance Tips For Working On Your Used Truck
There’s nothing quite like wrenching on your own truck. Whether you’re swapping out filters in your driveway or getting greasy under the hood, working on your own rig gives you that classic Texas pride—and a little more confidence every time you turn the key.
At Lone Star Auto Brokers, we know a thing or two about used trucks. We sell ‘em, we upfit ‘em, and yes, we’ve put in the weekend work ourselves. If you’ve recently bought a used truck in Arlington (or are thinking about it), here are some easy DIY maintenance tips to keep your ride running strong—and looking sharp.
1. Keep Your Fluids Fresh
It sounds basic, but we see it all the time—folks forgetting to check the essentials. Get in the habit of inspecting your oil, coolant, transmission fluid, brake fluid, and windshield washer fluid once a month.
Don’t just look at the level. Pop the cap and take a peek at the fluid color. Dark, burnt, or gritty fluids are a sign it’s time for a change. For oil, aim for every 3,000 to 5,000 miles, depending on the truck and your driving habits.
Pro tip: Keep a clean funnel and a few quarts of your go-to oil in the bed or toolbox. You never know when you’ll need a quick top-off.
2. Stay Ahead of Battery Trouble
Texas heat can do a number on your battery, especially in older trucks. Check for corrosion on the terminals and give them a quick clean with a wire brush and a mix of baking soda and water.
A simple voltmeter (they're cheap at most auto parts stores) will tell you if your battery is still holding a charge. If you’re reading less than 12.4 volts regularly, it might be time to plan for a replacement.
3. Tire TLC
Used trucks often come with a bit of tire wear, so it’s smart to start your ownership off with a good rotation and pressure check. Keep your tires inflated to the recommended PSI (found inside the driver-side door jamb) and rotate them every 5,000 miles or so to promote even wear.
Got a lift kit or aftermarket wheels? Make sure your alignment is on point. Misalignment can cause uneven tread wear fast—and that means less grip and more money spent down the road.
4. Don’t Neglect the Undercarriage
Whether you’re working ranch roads or just surviving I-20 construction, your truck’s undercarriage takes a beating. Keep an eye out for rust, especially around mounts, brackets, and frame welds.
A pressure washer is your best friend here. Give the underside a good rinse after muddy weekends, salty roads, or off-road detours. If you’re doing any upgrades (like a custom exhaust or lift), it’s also the perfect time to spray on a little undercoating protection.
5. Upgrade with Confidence
