Our Story
Built for Truckers By Truckers
Truck City Diesel has been serving heavy-duty drivers for over 15 years — first in Lake Bluff, IL, now in Milwaukee, WI. Same crew, same standards, same commitment to getting you back on the road.
Our Story
Where We Came From
We started in Lake Bluff, Illinois and spent over 15 years building a reputation as the shop that truckers trusted. No runaround, no upsells — just honest diagnostics and solid work on every make that rolled through the door. When eminent domain forced us out of our Lake Bluff location, we didn't close up. We relocated to Milwaukee, Wisconsin and kept right on wrenching.
Our Milwaukee shop at 6242 N 64th St is a full-service facility equipped to handle everything from routine preventive maintenance to full engine overhauls. The same technicians, the same work ethic, and the same network of industry partners we've built over a decade and a half — now serving Wisconsin's trucking community.
