Decoding Drivetrain Talk: Driveshafts, Halfshafts, U-Joints, and More

When you’re talking about the undercarriage, you hear a lot of different names for the same parts. A customer comes into the shop complaining about a clunking noise, and depending on where they’re from or who they’ve been talking to, they might tell you they need a new propeller shaft, a halfshaft, or a CV…

Why U-Joints Still Rule the Heavy-Duty World

Walk into any shop today, and you’ll see constant velocity (CV) joints on nearly every passenger car and crossover that rolls into the bay. They are the undeniable standard for modern drivelines. But when a heavy-duty truck, full-size van, or large SUV pulls up, you’re almost always going to be staring at a traditional universal…

Fix It Right The First Time: Wheel Bearing Replacement Tips

Wheel bearings are an integral component of the drivetrain and suspension system, but because they are positioned behind the braking assembly, they are often overlooked until a failure becomes audible. Whether the symptom is a subtle vibration or a distinct metallic growl, a failing bearing is an inconvenience and a safety risk that requires immediate…

The Critical Role Of U-Joints In Trail And Work Truck Suspensions

We know that trail running and heavy duty hauling can push suspension geometry to the limit. Extreme articulation affects all parts of the suspension and drivetrain, including universal joints. While U-joints are technically part of the drivetrain, in many applications, they are absolutely linked to the suspension. You cannot have massive articulation and wheel travel…

CV Joints Vs. U-Joints – How Are They Different?

output shaft lined up perfectly with the differential pinion, we wouldn’t need complex joints. We’d just use a solid steel bar and call it a day. But we don’t live in a straight-line world. Suspensions move up and down, differentials sit at different heights than transmissions, and – most importantly – front wheels have to…
