“Great work”

Mikey F • Truck Mechanic at Scotty's Auto & Truck Service LTD, St. Catharines
★ ★ ★ ★ ★

“St. Amands has become my go-to mechanic because they consistently deliver quality work and honest advice. The team is professional, knowledgeable, and easy to talk to. They always walk me through what needs to be fixed, what can wait, and what’s urgent—something I really appreciate. Turnaround times are fast, and the pricing is more than fair for the level of service. It’s rare to find a shop where you feel genuinely looked after, but the mechanics at St. Amands make it easy to come back every time.”

“Bob and his guys are some very very genuine people. I would highly recommend them to anyone that is looking for automotive repair. My snowplow was needing some work done to it they got me in there right away and helped me get back on the road to finish my job. Would give 10 stars if that was an option.”

Change transfer case and differential fluids every 50,000-60,000 km
Upgrade to heavy-duty brake pads if you tow frequently
Check U-joints for play every time you rotate your tires
Don't ignore DEF or DPF warnings on diesel trucks—they will cause the engine to derate
Have your truck's suspension inspected annually, especially if you carry heavy loads frequently

Frequently Asked Questions

How much does truck brake service cost in St. Catharines? +

How often should I service my 4WD system? +

Do lifted trucks need special maintenance? +

Is the diesel truck maintenance schedule different from gas? +
Yes, diesel trucks require additional maintenance items including fuel filter changes, DEF system service, DPF regeneration management, and often more expensive oil changes due to higher oil capacity.
