Diesel & Driveline Repair
in Whitby, Ontario
Diesel and gas vehicle repair for Whitby drivers — from our shop in neighbouring Ajax, a short drive west on Highway 401.
Plenty of Whitby shops change oil and rotate tires. Fewer diagnose electrical faults past the trouble code, balance driveshafts, or rebuild a transmission instead of quoting a replacement. For that work, Whitby drivers head one town over.
Rick Ferreira opened Midway after decades in automotive repair, machining and fabrication. Whitby customers bring us diesel pickups, commuter cars, contractor trucks and snow-removal vehicles. Every job starts with diagnosis, not a parts list.
Midway Driveline is located at 200 Fuller Rd Unit #8, Ajax, ON L1S 7G9 — a short Highway 401 drive west from Whitby into Ajax. Drivers from Whitby are welcome.
