Your Driveline Transfers Power From the Transmission to the Wheels.
The driveline includes the components that carry rotational power from the transmission or transaxle to the wheels.
Depending on the vehicle, that may include CV axles, driveshafts, U-joints, differentials, transfer cases and axle shafts.
When driveline components wear, loosen or lose proper lubrication, you may notice clicking, vibration, clunking, shuddering or noise that changes with vehicle speed or acceleration.
At Nutley Street Service Center, we inspect the related driveline components together so we can identify where the problem is actually coming from.
Reliable Power Transfer Depends on Healthy Driveline Components.
Joints, shafts, axles and gear assemblies all need to operate smoothly while handling torque and vehicle movement.
CV Axles & Joints
CV joints allow power to reach the wheels while accommodating steering and suspension movement.
Driveshafts & U-Joints
Driveshafts transfer torque between major drivetrain components, while U-joints allow changes in operating angle.
Differentials
Differentials distribute power while allowing driven wheels to rotate at different speeds when turning.
Transfer Cases
On applicable all-wheel-drive and four-wheel-drive vehicles, the transfer case distributes power between drive axles.
Signs Your Driveline Needs Attention
Driveline problems often appear as noises or vibrations that change with acceleration, turning or vehicle speed.
How We Diagnose Driveline Problems
Driveline symptoms can overlap with transmission, wheel-bearing, tire and suspension problems, so diagnosis comes first.
Confirm the Symptom
We begin with the vibration, clicking, clunking, shudder or noise you have noticed and when it occurs.
Inspect Driveline Components
Applicable CV axles, driveshafts, joints, boots and mounting points are checked for wear, looseness or damage.
Check Differentials & Related Systems
Differential, transfer-case and related fluid or gear concerns are evaluated when they relate to the symptom.
Repair & Verify
Approved repairs are completed and the vehicle is rechecked for proper power transfer, noise and driveline operation.

Gear & fluid maintenanceDriveline Design Depends on Which Wheels Receive Power.
Front-Wheel Drive
Front-wheel-drive vehicles commonly use CV axles to transfer power from the transaxle to the front wheels.
Rear-Wheel Drive
Rear-wheel-drive vehicles commonly use a driveshaft and rear differential to deliver power to the rear wheels.
All-Wheel Drive
AWD systems may use transfer units, additional driveshafts, differentials and axle assemblies to distribute power.
Four-Wheel Drive
Many four-wheel-drive systems use a transfer case and front and rear driveline components to provide power to both axles.
Gear Assemblies Also Depend on The Correct Fluid.
Differentials and transfer cases contain gears, bearings and other components that rely on specialized lubricants.
Depending on the vehicle, these fluids may have maintenance intervals based on mileage, time or operating conditions.
Towing, heavy loads, frequent stop-and-go driving or severe operating conditions can also influence maintenance needs.
Diagnose the Driveline Before Replacing the Wrong Component.
A vibration under acceleration does not automatically mean a driveshaft is bad, and clicking does not always come from the same component.
Our technicians consider the vehicle configuration, symptom and related drivetrain components so repairs are based on what is actually worn, loose or damaged.
Common Driveline Repair & Maintenance Questions
The driveline includes the components that transfer power from the transmission or transaxle to the driven wheels. Depending on the vehicle, this can include CV axles, driveshafts, joints, differentials and transfer cases.
Repetitive clicking during turns is commonly associated with wear in an outer CV joint, although inspection is needed to confirm the source.
Acceleration-related vibration can involve CV joints, driveshafts, U-joints, mounts, tires or other drivetrain components. The exact cause depends on the vehicle and when the vibration occurs.
Many vehicles have maintenance recommendations for these fluids, but intervals vary by vehicle and operating conditions. The manufacturer's schedule and service history should guide the recommendation.
