Why Diesel Doctors
A service truck and a full shop. One phone number.
Some outfits only run road calls. Some only work in a bay. We do both, so a fix on the shoulder can turn into a proper repair in our shop without starting over with somebody new.
Fixed where you sit
Brake adjustments, electrical, batteries and plenty of tire work get done on site. Bigger jobs come to the bays, and we'll tell you which on the call.
Tires on the rack
Bridgestone, Michelin and Yokohama in stock for steer, drive and trailer positions. We carry Firestone, Bandag and Dayton too.
Pay like you do at the fuel desk
Comchek, EFS, T-Chek, TCH and Fleet One checks, AMBEST Direct Billing, every major card and cash.
AMBEST certified

Heavy-duty alignment
Square axles. Longer-
lasting steers.
A truck that pulls eats steer tires and wears out the driver. We do alignments in our own bay on a Rotary R5000HD, an electronic aligner built for trucks and buses at 19,500 lb GVWR and up.
It grips the wheel at the bolt circle, where a bent rim can't throw off the reading, and it measures axle offset on every truck. Pair an alignment with a new set of steers and the rubber starts out square.
- Built for 19,500 lb GVWR and up
- Bolt-circle wheel mounting
- Axle offset on every job
- Wireless measuring heads
Inside the shop
Parts on the shelf. Tires on the rack.
When the part you need is already on our shelf, you're not parked waiting on a delivery. This is what it looks like inside on Hovis Rd.
From the road
Drivers say it better.
“I had a flat tire on my truck, and these guys were amazing. Very friendly, fast, and professional service. They changed the tire in no time.”
“They take their job seriously, show up on time, and provide fast, professional service. If you need reliable roadside assistance, they're the ones to call.”

Charlotte, North Carolina
Queen City built. Hornet's Nest tough.
Charlotte has been a freight town for a long time. I-85 and I-77 cross here, and trucks from all over the East Coast roll through on the way to somewhere else.
Our shop sits on Hovis Rd, down the street from the CSX intermodal terminal where containers come off the train and onto chassis. Pulling a box out of that yard and something doesn't sound right? We're close.
The story goes that a British general called Charlotte a hornet's nest of rebellion back in 1780. Folks here took it as a compliment and kept it. We fix trucks with the same stubborn streak, and the flag on our road truck is there on purpose.
All three, minutes from the shop.
