Commercial truck repair in Romeoville, IL
Get the truck back to earning. Truck Clinic is a commercial truck repair shop off Anderson Drive in Romeoville, IL: 65+ people and twelve services in one building, minutes from I-55 and I-355. Diesel engine and drivetrain repair, electrical and aftertreatment diagnostics, air brakes, suspension, tires, trailer repair and DOT inspections, for owner-operators and fleets across Will County and the Chicago metro.
If you searched "commercial truck repair near me" from a truck stop on I-55, here is how it goes: tell us the fault code and what the truck is doing, we diagnose it and put a price in writing, and nothing is opened up or ordered until you approve it. Same-day is realistic when a bay is open; call first and we'll say whether today is one of those days.
Open six days a week. We're a shop, not a roadside service — the truck comes to us, and we'll say up front whether it should be driven over or towed.

Our services
Which semi truck and trailer repairs do you handle in-house?
All twelve at one address, so a truck that comes in for a derate and leaves with a brake stroke out of spec gets both handled in the same visit. Engine, transmission and differential work, electrical and computer diagnostics, DPF and DEF systems, air brakes and suspension, tires and alignment, heating and A/C, oil service, DOT inspections and scheduled fleet maintenance — for the tractor and the trailer behind it.
Also: Tire mounting & balancing · Truck & trailer repair and alignments · Diesel oil changes · Heating & A/C
Not sure which one the truck needs? Start with computer diagnostics — the code decides the bay — or read how to choose a commercial truck repair shop in the Chicago area before you hand one over.
How it works
What happens between the fault code and the invoice?
The same three steps for one owner-operator truck and a forty-unit fleet. No work starts on a verbal estimate, and no part is ordered on a hunch.
01Tell us the fault code
Call or send the form with the code, the engine and what the truck is doing — no-start, a derate counting down, low air, a lamp that won't clear. We tell you whether it needs a bay today, a part ordered first, or a tow instead of a drive over.
02We diagnose and quote
A full scan, then the measurements behind it: boost and rail pressure, DPF differential pressure, brake stroke, voltage drop across a suspect ground. The findings and the price go to you in writing before anything is opened up.
03You approve, we repair
Nothing is ordered or taken apart until you say yes. You get the findings and the quote in writing, so your maintenance log and the next inspection have the record.
Why fleets and owner-operators use us
Why keep the whole fleet with one diesel mechanic?
A diesel no-start, a derate on the dash, a trailer with a dragging brake, or a fleet maintenance schedule that has to hold across the whole fleet — it's handled in-house by 65+ people at one address in Romeoville, with full computer diagnostics on site rather than sublet. One shop holds the history, so the intermittent fault that only shows on cold mornings gets chased by the people who saw it last time.
The trade-off is the one every fleet already knows: a brake stroke caught in the bay is a line on the write-up, while the same brake found at a roadside inspection is an out-of-service order and CSA points. The arithmetic is in what a truck breakdown really costs, and what the I-55 and I-80 corridor does to a truck is in truck repair along I-55 and I-80.
- Everything in one building
- Engine, drivetrain, air brakes, electrical, heating and A/C, DPF and DEF, tires, alignment and DOT inspections: twelve services at one address, so a truck rarely leaves for a second appointment.
- You see the measurements
- Findings come with the measurement that failed, not just the code, before a price is quoted, and no work starts until you approve it.
- Trailers get the same write-up
- Semi truck repair and trailer repair share the bays: trailer brakes, suspension, lights, air lines and alignment are measured and quoted the same way as the tractor.
- Built for corridor duty
- Will County intermodal work — short runs, long idles, constant stops — is harder on brakes, DPFs and batteries than highway miles. We see that pattern every week, which shortens the diagnosis.
Where is the nearest truck repair shop to I-55 and I-355?
Off Anderson Drive in Romeoville, minutes from both corridors, and we take trucks from Romeoville, Bolingbrook, Joliet, Naperville, Aurora, Plainfield, Lockport, Lemont, Woodridge and Chicago.
From the Joliet intermodal yards and the I-80 interchange it's a short run north on I-55; from Bolingbrook, Woodridge and Naperville the shop is a few minutes past the I-355 interchange. If the truck is limping with a derate counting down, low air or a charging fault, the first question is whether it can be driven over at all.

Questions
Before you call
How much does commercial truck repair cost near Romeoville?
It depends on three things: how long the diagnosis takes, whether the part is OE or aftermarket, and how many bay hours the job needs, so we don't quote a flat figure before we've looked. What you get instead is the order: we diagnose, we write up what we found with the measurements, and you get a written price. Nothing is opened up or ordered until you approve it. See what to ask a truck repair shop before the first job.
How fast can a truck repair shop near me get my truck into a bay?
Same-day whenever a bay is open; call early and we'll say whether today is realistic. Shop hours: Monday - Friday: 7:00 AM - 5:00 PM; Saturday: 7:00 AM - 12:00 PM; Sunday: Closed. We're a shop, not a roadside service, so the truck comes to us at 565 Anderson Dr Unit B, and a call ahead is what gets it into the schedule instead of the lot.
Can you fix a semi truck that is in a 5 MPH derate?
Yes. A derate is the engine protecting itself — usually a DEF quality fault, a NOx sensor, low SCR efficiency or a DPF soot load past its limit — so clearing the code without fixing the cause just restarts the countdown. We read the fault, repair what triggered it, then reset the derate. See 5 MPH derate resets.
Do you work on every truck make, and on trailers too?
Heavy-duty diesel across all makes: engine, transmission and differential, plus the electrical and emissions systems around them. Trailers come through the same bays for brakes, suspension, lights, air lines and alignment. If you're not sure, call with the engine and the fault code and we'll tell you before you drive over. See truck and trailer repair.
Can a DOT inspection and the repair be done in the same visit?
Yes. The annual inspection is done on site, and if something fails we show you the measurement it failed on — brake stroke, tread depth, a leaking air line — and quote the repair. You can fix it here the same visit or take the report elsewhere. See truck and trailer DOT inspections.
Do you take fleet maintenance from Joliet, Bolingbrook and Naperville?
Yes. Fleets from the ten towns we serve — Romeoville out to Joliet, Bolingbrook, Naperville, Plainfield, Aurora, Lockport, Lemont, Woodridge and Chicago — run their PM schedules, DOT inspections and repairs through the shop. One address keeps the service history in one place, so the next quote and the next inspection start from the truck's record instead of from zero. See fleet truck maintenance.
