What Maintenance Services Are Required After 100k Miles?

Hitting the 100,000-mile mark in your truck’s life is no small feat—congrats! But this milestone also signals the start of a new phase: advanced maintenance. Whether you're managing a single service body truck or an entire commercial fleet, regular truck maintenance is critical to keeping your rig running strong beyond six figures. At Texas Truck Repair, we specialize in helping drivers extend the lifespan of their vehicles with expert truck repair and maintenance services across Texas.

Why 100k Miles Is a Turning Point for Truck Maintenance Once a diesel truck or semi truck crosses 100,000 miles, it’s already proven reliable. But without preventive maintenance, even the toughest rigs can start showing signs of fatigue. Components wear out. Systems become less efficient. Fuel economy drops. It’s the perfect time to schedule comprehensive vehicle maintenance and avoid costly breakdowns down the road.

Key Maintenance Services to Schedule After 100,000 Miles Engine Inspection & Repair Engines are the heart of your truck. At 100k miles, issues like cummins x15 fuel pump problems, valve timing, or compression loss can surface. We offer full diesel engine repair, valve adjustment, and engine diagnostics to catch any hidden problems early. Our truck engine service includes checking for leaks, unusual noises, and signs of wear.

Transmission Fluid Change One of the most overlooked services in truck maintenance is transmission care. A transmission fluid change at 100k can extend the life of your drivetrain. We also provide full truck transmission repair and clutch repair services for both manual and automatic setups.

Brake System Overhaul At this stage, your brakes have done a lot of heavy lifting. It’s crucial to check for worn pads, damaged rotors, or failing brake lines. We specialize in brake repair, brake line repair, and even mobile brake repair—convenient for fleet managers and solo drivers alike.

Suspension & Alignment Check High mileage trucks often suffer from sagging suspensions and poor alignment. This affects ride quality and tire life. Our suspension maintenance and wheel alignment services keep your truck handling like new.
