Mobile and Roadside Driveline Service and Repair in West Nyack, New York

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. 

How Your Drivetrain Works

Your drivetrain is how your wheels get power. It consists of your transmission, driveshafts, differentials, and drive axles. Your transmission receives power from your engine and optimizes it using a series of gears. Your transmission then sends power to your driveshaft, which then uses a series of differentials (depending on the size of your truck) to send power to your drive axles. Your drive axles are directly connected to your wheels and are responsible for keeping your car moving. 

How Do Differentials Work

Open Differentials

Open differentials operate based on the path of least resistance. Whichever wheel has the least resistance will receive the most amount of power. This design allows for your wheels to travel different distances while turning. Although open differentials are the most common type of differential, they’re not the greatest for construction sites and other rough terrains.

Locking Differentials

Locking differentials ensure that 50% of your engine’s power goes to each rear wheel. This type of differential counteracts the path of least resistance using either a pin-based lock or a magnetic lock. Locking differentials are the ideal choice for offroad and rough terrain situations. However, they are not good for on-road driving. Since your inner wheel will always spin less than the outer wheel when turning, a locking diff will break apart if used on the dry road too often. Due to this, most locking differentials have to be engaged manually.  

Limited Slip Differentials

Limited slip differentials are a mix of both locked and open differentials. They allow each wheel to spin independently as needed but stop one wheel from having 100% of the power on uneven terrain. Limited slip differentials generally work in tandem alongside brake sensors or torque sensors.
