Park your rig at A & Z Truck Repair and Services in Liberty, MO, and you’ll discover a shop that blends dealership-level diagnostics with the hustle of a roadside rescue crew. Owner-technician Aron runs his mobile unit out of 1508 Glen Brook Ln, tackling everything from emergency coolant leaks to full brake jobs—often the same day you call. Over-the-phone quotes are clear, travel fees are minimal, and no matter how many times your dispatcher changes the plan, Aron stays “reliable and responsive,” rolling wherever the load takes you. Fleet managers appreciate his digital inspection reports; independent owner-operators love the straight talk, fair pricing, and parts sourcing that beats big-box stealer-ships by miles. Whether your box truck is stuck at a warehouse dock or your Class 8 needs an on-site PM, A & Z keeps Kansas City freight rolling and CSA scores clean. 🚚⚙️
