Trailer Repair in San Antonio TX
Heavy-duty trailers are subjected to ongoing mechanical stress, load fatigue, and environmental wear, making regular repair not just important—but essential for operational safety and compliance.

Our services address the mechanical core of each unit, not just cosmetic or quick-fix needs.
Here are the types of repairs we regularly perform as part of our heavy-duty trailer service process:
- Air brake overhauls include S-cam bushing replacements, valve inspections, and diaphragm servicing for brake response consistency across long-haul conditions.
- Kingpin and fifth-wheel resurfacing prevents trailer disconnection risks and ensures clean coupler engagement for highway stability.
- Suspension rebuilds focus on damaged leaf springs, worn torsion arms, and degraded air ride components across multi-axle trailers.
- Landing gear repairs involve hardware replacements and structural welding to reinforce mounting points and frame integrity.
We provide heavy-duty trailer repair services in San Antonio TX, which is based on a clear diagnosis, strict part sourcing standards, and a repair plan matched to trailer function. We also offer documentation for inspection readiness.
Diagnostics for Heavy Trailer Systems
Correcting trailer issues starts with identifying the exact mechanical faults. Our team uses diagnostic systems to evaluate electrical, braking, and hydraulic issues instead of relying on surface symptoms. These checks are done at the start of every repair session to avoid unnecessary part replacements. Computerized ABS diagnostics allow us to locate failed wheel sensors and solenoids in Class 8 trailers. Thermal imaging helps us spot brake drum overheating or bearing drag before they become road hazards. If a trailer has liftgates or dump mechanisms, we use hydraulic pressure testing to verify the entire system’s stability under load.
Our approach for the best trailer repair in San Antonio TX, also covers DOT inspection points. This includes inspecting lighting circuits, coupler height, landing gear performance, and air system leaks. We ensure that compliance problems are addressed during repairs—not after. Whether your trailer has standard components or advanced control systems, our methods isolate the issue fast.
Our Process for Trailer Repairs
We follow a structured, repeatable process for repairing trailers that ensures consistency, safety, and long-term performance across different trailer classes. Each step is designed to meet operational demands and inspection standards.
Here are the main stages of our repair process and what each step includes:
- Full Condition Assessment
We conduct a visual and diagnostic inspection that covers frame alignment, braking systems, suspension, and coupler mechanisms to document repair needs before any work begins.
- Repair Scope by Trailer Type
Each plan is built around the trailer’s design—drop decks, reefers, flatbeds—so that structural and mechanical fixes meet the specific use case and expected load.
- Approved-Standard Parts Only
All replacement parts meet FMCSA or original manufacturer requirements, which helps maintain compliance during road checks and ensures no future compatibility issues.
- Digital Service Record
We record each step of the trailer repair in San Antonio TX, and provide documentation for audits, fleet logs, and internal reviews—ideal for large operations that track trailer service history.

FAQs
Wiring inside trailer walls or junction boxes can corrode or short due to water exposure. We test voltage flow across connectors, grounds, and internal harnesses.
This usually points to worn or misaligned suspension parts. Torsion arms, air bags, or spring mounts could be damaged. We check each side under simulated load conditions.
Yes, especially after hub replacements or bearing work. Loose fasteners can cause uneven load distribution and rim damage. We retorque based on manufacturer specs after each related repair.
Yes. We handle repairs on custom, stretched, and specialty trailers by adjusting our jigs and tools to suit non-standard axle spreads or frame lengths.
