Mobile Truck Repair in Harleyville, SC

Harleyville sits on I-26 at Exit 177 (SC-453), about 47 miles up the interstate from our Charleston base. It is a small town carrying a lot of heavy iron: the Argos USA cement plant and the Giant Cement operation with its own limestone quarry, mixer and dump traffic on US-178 and SC-453, and line-haul trucks running the last stretch of I-26 before the I-95 junction.

It is also scale country. SCDOT runs weigh stations on both the eastbound and westbound sides of I-26 between Exit 172 (US-15) and Exit 177, and a truck that gets written up on the scale is a truck that needs a wrench right there, not a tow to a shop 45 minutes away. There is a Peterbilt dealer at Exit 177, but a dealer bay means a queue and a hook. Fleet Doc brings the shop to the truck instead – roadside, at the truck stop, in a plant yard, or on the shoulder.

We handle roadside truck repair, semi truck tire replacement, brake and air system work, diagnostics, electrical, jump starts and trailer repairs, 24 hours a day.

• I-26 Exit 177 (SC-453) – the Harleyville Truck Stop, the SC-453 ramps, and the Peterbilt dealer lot at the top of the exit.
• The I-26 weigh stations between Exit 172 and Exit 177 – both directions. Air leaks, lights, brakes and tire defects found on the scale are our most common call up here.
• I-26 Exit 172 (US-15) toward St. George and Holly Hill, including the Four Hole Swamp stretch where there is nowhere good to sit.
• I-95 Exit 82 (US-178) – the exit signed for Harleyville and Bowman, and the US-178 run between them.
• The cement plants and quarry roads off US-178 and SC-453, for mixers, dumps and yard equipment.
• The approach from Charleston – Exit 187 (SC-27, Ridgeville) and Exit 194 (Jedburg Road) with its travel plaza, both on our way in.

Class 6 through Class 8 – tractors, trailers, dumps, mixers, box trucks and straight trucks. Heavy duty only.

Start with which road you are on – I-26, I-95 or US-178 – then your exit number or mile marker and direction of travel. Add the nearest landmark (the truck stop at Exit 177, the scales, the dealer lot, a plant gate), what the truck is doing, and whether you are loaded. Harleyville typically runs 45 to 60 minutes from our Charleston base once a truck is rolling, so the more we know up front, the better the odds we arrive with the right part on board.

Is there a mobile diesel mechanic near the Harleyville exits on I-26?

Yes. Fleet Doc runs mobile heavy-duty service to I-26 Exit 177 (SC-453), Exit 172 (US-15) and the weigh stations in between, 24 hours a day. We are a mobile operation out of Charleston – there is no counter to walk into, we come to wherever your truck stopped.

How long does it take you to reach Harleyville from Charleston?

Harleyville is about 47 miles up I-26 from our Charleston base, and once a truck is rolling we are typically 45 to 60 minutes out. Actual response depends on the time of day, what is already in front of you, and whether we need to pick up a specific part first. Call and we will tell you straight what the window looks like.

My truck got shut down at the I-26 scales near Harleyville. Can you fix it there?

That is one of our most common calls on this stretch. The SCDOT weigh stations sit on both sides of I-26 between Exit 172 and Exit 177, and most out-of-service write-ups there are air leaks, brake defects, lights or tires – all repairs we do at the truck. Tell dispatch the direction of travel and which scale you are sitting at.

Do you replace semi truck tires on I-95 at Exit 82 between Harleyville and Bowman?

Yes. I-95 Exit 82 is the US-178 exit signed for Harleyville and Bowman, and we cover that exit and the US-178 stretch between the two towns. We carry new and used drive, steer and trailer casings and change them on the shoulder or in a lot.

Do you work on mixers and dump trucks at the Harleyville cement plants?

We do. Harleyville has two cement operations – Argos and Giant Cement – plus a working quarry, and that traffic is hard on air systems, brakes and tires. We service mixers, dumps and other heavy equipment in the yard or wherever the unit went down, same as we do on the interstate.

Are you available at night and on weekends around Harleyville?

Yes – Fleet Doc dispatches 24/7, including nights, weekends and holidays. A breakdown at 2 a.m. on I-26 gets the same phone number and the same truck as one at 2 p.m.
