2 Front CV Axle Shaft Assemblies for 2010-2016 Chevy Equinox & GMC Terrain 2.4L, 2016 1st Design

Two Front CV Axle Shaft Assemblies for Equinox and Terrain 2.4L

Two-piece front CV axle shaft assembly set for the listed Chevrolet Equinox and GMC Terrain applications equipped with the 2.4L four-cylinder engine.

Critical fitment warning: This set is limited to the 2.4L L4 engine. For 2016 vehicles, the source specifically requires the 1st Design. The source does not define the design break by VIN, production date, or physical feature and does not specify FWD versus AWD, transmission, ABS tone-ring configuration, compressed lengths, inner or outer spline counts, seal diameters, axle-nut threads, or intermediate-shaft connections. Confirm the VIN, 2.4L engine, 2016 design version, drivetrain, transmission, original references, splines, lengths, inner-joint styles, seal surfaces, and axle-nut threads before ordering.

Vehicle Compatibility

• 2010–2015 Chevrolet Equinox — 2.4L L4
• 2016 Chevrolet Equinox — 2.4L L4, 1st Design only
• 2010–2015 GMC Terrain — 2.4L L4
• 2016 GMC Terrain — 2.4L L4, 1st Design only

Not confirmed: V6 engines, 2016 2nd Design, or any unlisted engine, model year, drivetrain, transmission, or configuration.

Position and Quantity

• Axle position: Front
• Quantity: Two CV axle shaft assemblies

The source confirms a two-piece front set but does not explicitly assign each reference number to the left or right side. Compare both replacement assemblies with the corresponding originals before installation.

Reference Numbers

15934402, 20906475, 15934401, 20881990, 20906474, NCV10641, NCV10642, 661516, 66-1516, 661517, 66-1517

Reference numbers are provided for comparison. Match them together with the VIN, engine, 2016 design version, drivetrain, transmission, original axles, compressed lengths, splines, inner-joint designs, seal surfaces, and axle-nut threads.

Package Contents

• Two front CV axle shaft assemblies

The source does not confirm inclusion of axle nuts, retaining clips, transmission seals, intermediate shaft, support bearing, mounting hardware, or fluid. Inspect the product images and obtain any one-time-use parts required by the vehicle service procedure.

Installation Notes

CV axle replacement affects steering, suspension, wheel-bearing preload, transmission sealing, and vehicle safety. Professional installation is recommended. Before installation, compare each replacement with the corresponding original axle, including side, overall and compressed length, spline counts, tone ring, inner-joint connection, seal surface, shaft diameter, and axle-nut thread. Inspect the wheel bearings, hub splines, control arms, ball joints, transmission or transfer-case seals, and related components. Do not pull on the shafts or damage the CV boots. Seat each inner joint fully, replace required seals and retaining hardware, correct fluid level as needed, and torque axle nuts and suspension fasteners to vehicle-specific specifications. Verify there are no leaks, warning lights, binding, clicking, or vibration before road use.

Frequently Asked Questions

Does this fit V6 models?
No V6 fitment is confirmed. The source specifies the 2.4L L4 engine only.

What does 2016 1st Design mean?
The source requires 1st Design but does not provide the VIN break, production date, or physical identifier. Verify the VIN and both original axles before ordering.

Are both front axles included?
The source identifies a two-piece front set. It does not explicitly map every reference number to a side, so compare both assemblies with the originals.

Does this fit FWD and AWD?
Drivetrain coverage is not stated. Confirm the VIN, drivetrain, references, splines, and axle lengths.
