Subaru Forester & Impreza Front Left and Right CV Axle Shaft Assembly Set

This BDFHYK two-piece front CV axle shaft assembly set is an OE-style aftermarket replacement based on the original listing data for Subaru Forester 2003-2008 and Subaru Impreza 2004-2006 applications. It includes one front-left and one front-right axle for customers planning a two-side repair or replacing both assemblies during the same service. Common user concerns include clicking while turning, vibration under acceleration, grease around torn boots, uncertainty about which axle side is needed, and whether both sides actually require replacement.

Subaru Forester & Impreza Front CV Axle Fitment

Vehicle	Years	Position
Subaru Forester	2003-2008	Front Left + Front Right
Subaru Impreza	2004-2006	Front Left + Front Right

Confirm the exact year, trim, engine, transmission and drivetrain before ordering. Subaru axle configurations can differ by powertrain and build specification, so compare both removed shafts with the replacement set.

OE and Interchange Numbers for This Subaru CV Axle Set

Cross-check 28321FE151, 28321FE181, 28321SA030, 28321SA033, 28321SA050, 28321SA051, 667281 and NCV66503 against the removed axles, an OE catalog or a qualified parts lookup. A matching number should be confirmed together with the vehicle configuration, front left/right position, spline ends and retaining method.

When to Inspect the Subaru Forester or Impreza CV Joint

Customers researching a subaru forester cv joint, subaru forester cv joint replacement or subaru impreza cv joint replacement commonly want to identify the source of clicking or vibration before purchasing a complete axle set. Inspect the front driveline when the vehicle shows:

Clicking or popping while turning.
Shudder or vibration under acceleration.
Grease around a front wheel, control arm or splash shield from a damaged boot.
Clunking when torque changes between acceleration and deceleration.
Visible boot cracking, loose clamps, joint play or shaft damage.

Wheel bearings, tires, engine or transmission mounts, suspension joints and brake components can create similar symptoms. These signs support inspection but do not guarantee that one or both axles are the cause.

What This Subaru Forester & Impreza CV Axle Set Includes

This listing supplies two axle shaft assemblies: one front left and one front right. The original description identifies protective CV joint boots, grease and retaining clamps as part of each assembly.

Fitment Checks Before Ordering This Subaru CV Axle Set

Verify year, model, trim, engine, transmission and drivetrain.
Confirm that the repair plan requires both front axle positions.
Match NCV66503 or another listed OE/interchange number.
Compare left and right shaft configuration, spline ends, seal surfaces, retaining methods and hub connections.
Check whether axle nuts, seals, clips or other one-time-use hardware must be replaced separately.

Subaru Forester & Impreza CV Axle Installation Checkpoints

Follow the applicable Subaru service procedure and keep the left and right assemblies identified. Inspect both wheel hubs, transmission seal areas, axle mating surfaces and surrounding suspension components. Do not force the splines or use the boots to pull the assembly into place. Confirm full engagement on both sides, tighten hardware to specification, and check for leaks, boot contact, abnormal noise and vibration after installation.

Package Includes

1 front left CV axle shaft assembly.
1 front right CV axle shaft assembly.

Q: How do I confirm this CV axle fits my Subaru Forester and Subaru Impreza?

A: Verify the listed model and year range, then confirm trim, engine, transmission, drivetrain, axle position, original shaft configuration, and at least one OE or interchange number. Model year alone is not enough when multiple driveline configurations exist.

Q: Which axle position does this listing cover?

A: This listing covers the front left and front right positions.

Q: How many CV axle assemblies are included?

A: The package contains two axle shaft assemblies: one front left and one front right.

Q: Which OE or interchange numbers can I use for comparison?

A: Cross-check the following references: 28321FE151, 28321FE181, 28321SA030, 28321SA033, 28321SA050, 28321SA051, 667281, NCV66503. Confirm a matching number together with the vehicle configuration and axle position.

Q: Is this a Genuine OEM axle?

A: No. This is a BDFHYK OE-style aftermarket replacement and is not represented as a Genuine or Official OEM part.

Q: What symptoms may lead to a CV axle inspection?

A: Common reasons to inspect the axle include clicking while turning, vibration or shudder under acceleration, grease around a split boot, clunking during load changes, or measurable joint play. Other wheel-end or driveline components can cause similar symptoms.

Q: Will replacing the CV axle automatically fix clicking or vibration?

A: Not necessarily. Clicking and vibration can also come from wheel bearings, tires, mounts, suspension joints, brakes, or other driveline components. Diagnose the source before replacement.

Q: Do both front CV axles need to be replaced at the same time?

A: This listing is already a left-and-right pair. Replace both only when inspection, service planning, or the repair order supports replacing both sides.

Q: What should I compare before installation?

A: Compare the original and replacement axle layout, spline ends, overall configuration, boot placement, seal surface, retaining method, hub connection, and left/right position. The axle should seat without forcing the splines or damaging the boots.

Q: Are a new axle nut, seal, clip, or other service parts included?

A: Only the axle assembly or assemblies listed in the package are confirmed. Check the vehicle service procedure for one-time-use nuts, seals, clips, cotter pins, or related hardware and obtain them separately when required.

CV Axle Buying Guide

Before purchasing a replacement CV Axle Shaft Assembly, confirm the key compatibility details below to ensure proper fitment.

1. Drivetrain Type

FWD – typically uses two front CV axles
AWD / 4WD – uses front and rear CV axles
RWD with independent rear suspension – may use rear CV axles

2. Left vs Right Axle Position

CV axles are usually sold by installation position:

Front Left (Driver Side)
Front Right (Passenger Side)

Left and right positions are determined from the driver’s seating position. Because the transmission is not centered, the two axles often have different lengths and joint designs and are not interchangeable.

3. Compatibility Details

ABS Tone Ring – required on certain vehicles for ABS sensors
Spline Count – must match the transmission and wheel hub
OE Part Number – the most reliable way to confirm compatibility

4. Estimated Installation Time & Tools

Professional mechanic: 1–1.5 hours
DIY installation: 3–5 hours

Floor jack and jack stands
Axle nut socket (30mm / 32mm / 36mm)
Breaker bar
Torque wrench
Ball joint separator or pickle fork

Ensure the vehicle is securely supported before starting installation.
