Semi Truck Repair in Midland, TX
Semi truck and trailer repair for owner-operators and fleets across the Permian Basin. Chris’s Diesel Service handles engine and drivetrain work, air and brake systems, trailer repair, electrical, and full-vehicle inspections in a 140 x 150 ft. shop built to take trucks this size indoors.
The Whole Rig. Tractor and Trailer.
A semi that is down is not a vehicle problem, it is a revenue problem. Four areas of work, all handled in the same shop so the truck does not bounce between vendors while your load sits.
Engine & Drivetrain
Heavy diesel diagnostics, in-frame and out-of-frame engine work, clutch and transmission repair, differentials, and driveline. In-house rebuilds by Chris when the engine is past repair.
Air & Brake Systems
Air leaks, compressors, dryers, and valves. Brake shoes, drums, chambers, and slack adjusters. Brake stroke measured and recorded so the truck rolls through inspection clean.
Trailer Systems
Trailer brakes and air lines, suspension, landing gear, doors and floors, kingpins, and wheel-end work. Refrigerated trailer cooling units serviced as well.
Electrical & Lighting
Tractor and trailer wiring, lighting and markers, batteries and charging systems, starters, and ECM communication faults. Official Continental Battery and Bosch dealer.
Down. In the Shop. Back on the Road.
Downtime on a semi is measured in lost loads, not days. Here is how a down truck moves through this shop, and what you know at every stage.
Triage & Quote
Call us with the symptom and we triage on the phone. If the truck can roll, bring it in. If it cannot, our crane-equipped service truck can come to it. Diagnosis and a written quote come first, fast.
- Phone triage before the truck moves
- Field response available for trucks that cannot roll
- Diagnosis prioritized for down units
- Itemized written quote before repair begins
- Honest timeline based on parts availability
Repair & Updates
The truck comes inside the 140 x 150 ft. shop, out of the weather, and the repair runs on the quoted scope. Anything found during teardown is documented and quoted before the work expands.
- OEM parts when they exist, best standard when they do not
- Added findings quoted before scope grows
- Progress updates on multi-day jobs
- Trailer repaired alongside the tractor when both need work
- Brake and air readings recorded for your file
Verified & Released
The truck does not leave on faith. Air system holds, brakes measured, repair verified under load, and a road test before release. The paperwork goes with the truck.
- Road test before release
- Air leak-down verified to spec
- Brake stroke recorded per axle
- Work order and findings documented per unit
- Zero comebacks in 2025, and we intend to keep it that way
Built for Trucks This Size.
Most repair shops in Midland cannot physically take a semi indoors. This one was built for it. Full-size bays, heavy lifting capability, and a crane-equipped service truck for the rigs that cannot make it in.
- 140 x 150 ft. Shop Tractor and trailer come inside, out of the West Texas weather. No working in a gravel lot, no waiting on a bay that fits.
- 8,000 lb. Crane Truck For semis and equipment that cannot roll, our service truck comes to the yard or the lease road with the lifting capability to do real repair on site.
- Inspection Records Brake stroke, air system, tires, and lighting recorded per unit. Documentation formatted so it holds up at a roadside inspection or a DOT audit.
- Owner Sign-Off Every truck is checked and road-tested before release. Chris signs off personally. Zero vehicles returned for incomplete or incorrect repairs in 2025.
