Undercar Repairs in Port Huron
At Main Street Garage, we take a holistic approach to vehicle care, beginning with a thorough evaluation of your car or truck's foundation. Prior to inspecting the internal components of your vehicle, we prioritize ensuring that you have a strong undercarriage.
Our comprehensive undercarriage inspections and services address this vital but often overlooked area of your vehicle, affording it the care and attention it deserves.
Chassis
The chassis serves as the internal framework of your vehicle, providing support for various components such as the wheels, engine, transmission, driveshaft, differential, and suspension. A weakened or damaged chassis can lead to a weaker vehicle overall.
Custom Exhaust
A motor vehicle's exhaust system consists of piping that guides exhaust gasses from the engine to the outdoors. While its primary purpose is the removal of exhaust gasses, it can be modified to enhance engine power, reduce pollution, and minimize noise. Achieving these goals necessitates undercar service installation of a custom-made exhaust system.
Differential Flush
The differential is a critical vehicle component that compensates for variations in travel distance between the inner and outer wheels during turns. Typically located at the rear and under non-four-wheel-drive (FWD) vehicles, differentials often do not receive the same level of attention as engines. However, it is essential to understand that differential failure equates to vehicle failure.
Differentials
Differentials serve as the components responsible for transmitting engine power to the wheels. A key function of the differential is to distribute power to the wheels while permitting them to rotate at varying speeds, thus earning its name.
Driveline
The driveline represents a vehicle section that connects the engine and transmission to the wheel axles. This component consists of powertrain parts excluding the engine and transmission. A driveline failure translates to an immobilized vehicle, as energy cannot be transmitted from the engine to the wheel axles.
Shock Absorbers
Shocks, or shock absorbers, are mechanical devices engineered to smooth out rough road surfaces. They achieve this by converting kinetic energy into another form of energy. Properly functioning shocks minimize the impact of traveling over uneven terrain, leading to an improved ride quality and enhanced vehicle handling.
Struts
Much like shock absorbers (shocks), struts serve to dampen the effects of road surfaces as you drive. By absorbing road shocks, struts enable passengers to experience a smoother ride. Struts differ from shocks in that they provide structural support for your vehicle's suspension.

Suspension FAQs
How often should shocks be replaced?
Experts recommend that shocks be replaced at 50,000-100,000 miles. If you are a more aggressive driver or frequently drive on rough roads, they will wear out faster. Shocks don't go out all at once, they deteriorate slowly over time. If you are noticing problems with handling, making smooth turns or ride smoothness have one of the professionals at Main Street Garage inspect your shocks.
Are struts difficult to replace?
Replacing struts is simple and fast for a professional. Replacing your front struts yourself is not recommended, especially if you need a new complete strut assembly kit. When you get your truck's struts replaced you also need to have the front-end alignment checked. Ask the professionals at Main Street Garage to replace your struts and we will complete the work quickly and easily.
Is it necessary to get an alignment after strut replacement?
Main Street Garage recommends performing an alignment anytime shocks, struts or other steering and suspension components are replaced. Getting your vehicle's alignment within factory specifications ensures optimal tire wear and helps prolong the life of your tires.
What happens if I only replace one strut or shock?
If you replace only one shock or strut, it will create poor handling when changing lanes or driving over bumps. If your car is new, replacing only one strut or shock absorber may be ok since the opposite side shock is not worn out yet. Generally, Main Street Garage recommends replacing both shocks or struts.

What our clients are saying about us
We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!
I discovered Dale’s business, Mainstreet Garage, after moving to Port Huron in 2014. Before switching my major to Information Technology, I enrolled in the GM Automotive Service Educational Program at Delta College in Saginaw, originally intending to become a GM-certified mechanic. That training gave me a solid foundation—I’m fully capable of repairing my own vehicles and handle most of my maintenance myself. That said, there are times when I lack the lift, specialty tools, or the time to complete the repairs myself. Dale’s business stands out for one simple reason: they know what they’re doing, and they’re honest. On more than one occasion, I’ve brought in one of my vehicles with parts already in hand—either due to time constraints or the need for specialty tools—and they’ve still taken on the job. That’s rare. Most shops rely on parts sales as a key revenue stream and won’t touch a job unless they’re supplying everything themselves. Most recently, I had to undergo back surgery after starting the disassembly of my 2017 Equinox Premier AWD with the 3.6L LFX V6 and I was unable to replace every component behind the timing cover, along with the water pump, which has to come off anyway to access the cover. Dale’s team didn’t hesitate to step in and finish the job. I know, without question, that I can bring any of my vehicles to them and trust they’ll get it done—whether they’re providing the parts or not. That kind of flexibility and integrity is hard to find. If you’re looking for a shop that treats you right and knows their craft, look no further. Dale and his exceptionally competent team will take care of you. I can’t speak highly enough of these gentlemen, and I’m genuinely grateful to have a business I can trust.
Called for a quote and the guy was to the point. I’m so glad I came across this place. I haven’t even went here yet and seeing the reviews and the pricing. This is my new go to.
