Axles are an extremely important part of your drivetrain. Generally, they’re on either side of a differential and are responsible for transferring power to your wheels. These axles are constantly under a lot of pressure and stress. They have to withstand the enormous torque created by heavy-duty diesel engines. When axles are not maintained properly they tend to snap. This can cause quite a bit of damage, for your axles are directly connected to the rest of your drivetrain. Poor maintenance usually results in a lot of heat and friction, hence the snapping axle. Here at Fran Rock Truck Services, we’re heavy-duty axle experts. We’re more than capable of repairing or replacing axles as needed.

Heavy-duty trucks are constantly hauling a lot of weight. Bringing this weight to a stop would be impossible if not for extremely tough air brake systems. Unlike passenger vehicles that use fluid-based brakes to stop, semi-trucks and other large heavy-duty vehicles use compressed air to activate their disc or drum brakes. These systems rely on large compressors and a series of valves and lines to operate. Due to the sheer pressure being forced through these lines on a daily basis, brakes need to be maintained routinely to avoid severe damage. Here at Fran Rock Truck Services, we’re heavy-duty brake experts. 

Your diesel engine creates a lot of heat when running but you probably don’t notice because of your heavy-duty coolant system. The extreme amounts of heat are typically dissipated using large heavy-duty radiators. Coolant is pushed through your engine block by a large water pump. This coolant absorbs heat and then runs through your radiator. Your radiator then disperses this heat, therefore cooling your engine. Over time this coolant loses its ability to absorb heat and needs to be changed. For all your coolant system needs, Fran Rock Truck Services has your back. 

Modern-day diesel engines have a lot of computer-based systems. Everything from fuel injection to timing can be controlled by computers. This makes diagnosing issues fairly difficult. Here at Fran Rock Truck Services, we make the process easy. Our diagnostics technicians will connect to your truck’s ECU and run various high-tech tools. These tools will diagnose the issue, allowing us to go in and repair it. Don’t let annoying electrical issues slow you down. For all your electrical and diagnostic needs, come visit Fran Rock Truck Services. 

Your driveline is an incredibly important part of your heavy-duty vehicle. It’s what transfers power from your transmission to your differentials. Some vehicles have multiple drivelines, whereas others only have one primary driveline. Because your driveline hangs relatively low, it may come in contact with road debris. This can cause it to warp or break off entirely. Here at Fran Rock Truck Services, we’re driveline experts. Whether you need a driveline built or repaired, we can handle any type of service that comes our way. For all your driveline services, Fran Rock Truck Services has you covered.

Modern-day diesel engines are designed to be as environmentally friendly as possible. Although this is great for our climate and natural environment, it makes diesel engines a lot more complex. EGR and DPF systems are found on the vast majority of diesel engines and over time they both may have issues. Take the Cummins ISX15 for example. This engine is known for EGR valve leaks, which not only release more emissions into the atmosphere but can wreak havoc on your vehicle’s performance as well. Call us today to see what Fran Rock Truck Services can do for your truck’s emission control system.

Diesel engines are expected to work extremely hard on a daily basis. Although they’re generally reliable, they may break down if not properly maintained or overworked. Some of the more common engine damage includes blown head gaskets, fuel injection issues, and cracked oil pans. Here at Fran Rock Truck Services, we’re diesel engine experts. They’re our bread and butter, and we love to work on them. Our services are built around the idea of fast and effective service. Unlike other shops, you won’t be in for repair for extremely long times. We do good work, fast. For all your engine repair needs, Fran Rock Truck Services has your back. 

Although many may believe exhaust systems aren’t all that important, we’re here to announce the contrary. Exhaust systems are very important and need to be maintained regularly. They’re designed to do three very important things. Firstly, they divert exhaust fumes away from your passenger compartment. This protects the health of you and your passengers. Secondly, your exhaust is designed to control how much carbon is outputted into our atmosphere. Thirdly, your exhaust is responsible for noise suppression. Not only does this make you road legal, but it helps maintain the sanity of people who live near highways. 

As a North American truck driver, chances are many of your routes go through places that have drastically varying weather conditions. Although your truck doesn’t mind being in the hot southern states or cold Canadian provinces, you certainly will if you don’t have a good HVAC system. Here at Fran Rock Truck Services, we’re HVAC system experts. Is your A/C system not removing enough moisture from the air? Maybe your vents are clogged? Regardless of this issue, our technicians will get you back on the road in no time whatsoever. For all your HVAC system needs, Fran Rock Truck Services has your back.

Unlike other heavy-duty repair shops, our roadside technicians are able to perform complex repairs on a mobile basis. Of these complex repairs, we commonly work on hydraulic hoses, valves, and other related hydraulic assemblies. A hydraulic hose is designed to transfer hydraulic fluid to or between hydraulic components, all whilst protecting them from outside contaminants. A hydraulic hose failure generally means there is a breach in the system that’s allowing outside contaminants in. Not only will this drastically impact performance, but it may also lead to costly repairs down the road. Typically repairs of this complexity are undergone within a large shop, but here at Fran Rock, we have the tools and expertise to perform said repairs right from your job site.

All good preventative maintenance regimens start with adequate oil and fluid changes. All of the large moving components in your vehicle need some sort of lubricant. Generally, these lubricants are responsible for two things. Removing friction and absorbing heat. Take engine oil for example. It lubricates your pistons and camshafts so they don’t overheat, all whilst absorbing heat that’s dispersed using oil coolers. Other large components that use oil or fluid to lubricate their moving parts include your transmission and differentials. For all your oil and fluid needs, Fran Rock Truck Services has your back.

Your suspension is responsible for holding up the weight you haul around on a daily basis. Without your suspension, your heavy-duty vehicle’s frame would be scraping along the ground. There are a wide array of parts that need to be inspected and maintained on a routine basis. The first, and arguably most important, is your air suspension. Air suspension requires complex sets of airlines and valves, and is powered by large air compressors. If this system fails, you risk losing your load and putting others at risk. Other components that need maintenance include bushings, mounts, and most importantly, shocks. 

Your tires are the only part of your heavy-duty vehicle that touches the ground. Regardless of how well your engine is running, or how smooth your transmission shifts, without tires, your heavy-duty truck becomes close to useless. Over time tires will wear down. Although this is normal, their lifespan can be extended through proper maintenance. If tires are left on one side for long periods of time, their treads will wear out unevenly. This lowers the lifespan of your vehicle. If you rotate them on a regular basis, that tread will wear out evenly, therefore increasing their lifespan. For all your tire repair needs, Fran Rock Truck Services has your back.

Is your transmission acting up? Maybe you’ve lost a gear, or simply need a transmission fluid flush? Well, regardless of your issue, Fran Rock Truck Services is more than capable of handling any and all transmission issues that come our way. We’re transmission and clutch experts. It’s very important that you maintain your transmission on a regular basis. It’s responsible for optimizing the power from your engine using a series of gears. Without it, you’d have a lot of power that’s simply unable to reach your wheels. For all your transmission needs, Fran Rock Truck Services has your back.
