At Lone Star Trailer Services, we know dump trailers work hard — every day they lift, haul, and dump heavy loads that test every weld, hinge, and hydraulic. Whether you run a small contractor trailer or a full commercial end-dump, our technicians have the tools, experience, and dedication to keep your equipment operating safely and reliably.

We specialize in complete dump trailer repair, fabrication, and maintenance for all makes and models.

Hydraulic System Repairs

The hydraulic system is the lifeline of every dump trailer. When it fails, your trailer can’t perform. Lone Star provides complete hydraulic service, including:

• Cylinder rebuilds and replacements for leaking, bent, or weak lift cylinders

• Hydraulic pump repairs and replacements

• Hose replacements and leak detection

• Valve, fitting, and control testing for proper flow and pressure

• Hydraulic tank flushing and filter service to remove debris and contamination

We use only heavy-duty fittings and industrial-grade fluid to ensure smooth, powerful operation under load.

Frame & Body Repairs

Constant dumping, loading, and vibration can cause serious structural stress. We handle:

• Cracked or bent frame rails and cross members

• Weld repairs to side walls, floors, and tailgates

• Hinge and pivot point replacements

• Reinforcement of hoist mounts and stress points

• Dent and panel repair on steel or aluminum bodies

Our welding and fabrication work restores your trailer’s strength and keeps it aligned for years of dependable service.

Floor & Tailgate Repairs

Dump trailers take a beating in the bed — we can rebuild and strengthen every inch:

• Floor replacements using high-strength steel or aluminum plates

• Tailgate hinge and latch repairs

• Seal and gasket replacements to prevent leaks during hauls

• Hydraulic or air-assisted tailgate system repairs

• Tarp system repairs or new installations

We ensure your trailer dumps clean, closes tight, and seals properly for every load.

Electrical & Lighting Repairs

Reliable lighting and electrical systems are essential for DOT compliance and safety. We repair:

• Complete trailer rewiring for corroded or cut harnesses

• Light replacements — brake, turn, tail, and clearance lamps

• Connector plug and pigtail replacements

• Backup alarm and control wiring diagnostics

All electrical work is done with weatherproof connectors and sealed harness protection for long-lasting durability.

Suspension, Axle & Brake System Repairs

Your dump trailer’s suspension takes a pounding — especially with heavy loads. Lone Star technicians specialize in:

• Leaf spring and equalizer replacements

• Airbag and height control valve repairs

• Axle alignment and straightening

• Wheel bearing and hub service

• Brake shoe, drum, and air brake system repairs

• ABS sensor and valve diagnostics

We make sure your dump trailer runs smooth, straight, and stops strong.

Landing Gear, Hoist & Lift Component Repairs

We service all major dump trailer lifting and support components:

• Landing gear replacements or rebuilds

• Hoist inspection and repair (single, twin, or scissor hoists)

• Pivot pin replacements and lubrication points

• Grease system installation or maintenance

• Bed tilt sensor or hydraulic limit switch service

Every moving component gets inspected, tightened, and tested for safe, dependable operation.

Custom Fabrication & Reinforcement

For older or high-use dump trailers, we provide:

• Custom side-wall extensions

• Steel plate reinforcements

• New crossmember fabrication

• Custom tarp systems or brackets

• Modified rear gates or coal chutes

Whatever your trailer needs, we can build it, weld it, and make it work like new.
