What Does the Rear CV Axle Shaft Do?
The rear CV axle shaft assembly transmits rotational power from the rear differential to the rear wheel while allowing for suspension travel and steering angle. In RWD vehicles like the 2011-2014 Dodge Charger, Challenger, and Chrysler 300, the rear axle shafts must flex with the independent rear suspension while maintaining constant torque transfer. The constant-velocity (CV) joints at each end of the shaft allow this articulation without binding or losing efficiency.
When a CV joint wears out or the axle shaft itself becomes damaged, power delivery to the wheel is compromised, often producing audible clicking, vibration, or complete loss of drive on one side.
What Are the Symptoms of a Bad Rear CV Axle?
A failing rear CV axle shaft typically announces itself through several distinct symptoms:
- Clicking or popping noise during turns: Worn CV joints produce rhythmic clicking that increases with sharper turning angles and vehicle speed
- Vibration under acceleration: Damaged CV joints or a bent axle shaft create driveline vibration that intensifies when power is applied
- Grease on the inside of the wheel or around the CV boot: Torn CV boots allow lubricant to escape, leading to rapid joint wear and visible grease splatter
- Clunking when shifting from drive to reverse: Excessive play in worn CV joints causes audible impact when torque direction changes
- Loss of power to one rear wheel: Complete CV joint failure or shaft fracture results in one-wheel-drive operation or immobility
Ignoring these symptoms can lead to complete axle failure, potentially causing loss of vehicle control or expensive differential damage.
What Vehicles Does the APDTY 143854 Fit?
The APDTY 143854 rear left CV axle shaft assembly is engineered for the following specific applications:
| Year Range | Make | Model | Notes |
|---|---|---|---|
| 2011-2014 | Dodge | Charger | RWD only, excludes SRT8 |
| 2011-2014 | Dodge | Challenger | RWD only, excludes SRT8 |
| 2011-2014 | Chrysler | 300 | RWD only, excludes SRT8 |
Important: This axle is for rear-wheel-drive models only and does not fit SRT8 variants. SRT8 models use different axle specifications due to their higher-output drivetrains. Always verify fitment against your vehicle's VIN or consult the live compatibility chart on APDTY.com before ordering.

How to Replace a Rear CV Axle Shaft (General Overview)
Replacing a rear CV axle shaft requires basic mechanical skills, a jack and jack stands, and common hand tools. This overview is for informational purposes—always follow a vehicle-specific service manual and observe proper safety procedures.
- Secure the vehicle: Lift the rear of the vehicle, support it on jack stands rated for the weight, and ensure the transmission is in Park (automatic) or in gear (manual) with the parking brake applied
- Remove the wheel: Take off the rear wheel on the affected side to access the axle
- Disconnect the axle from the hub: Remove the axle nut (often a large center nut requiring significant torque to loosen) and any hub mounting bolts
- Disconnect the inboard CV joint: Unbolt or carefully pry the inboard joint from the differential, taking care not to damage the differential seal or surrounding components
- Remove the old axle: Slide the axle shaft out of the hub and withdraw the assembly from the vehicle
- Install the new APDTY 143854 axle: Insert the inboard CV joint into the differential until it seats with a click, then slide the outboard end into the hub
- Secure the axle: Install the hub nut and any mounting bolts, torquing the axle nut to manufacturer specification (often 150+ ft-lbs)
- Reinstall the wheel: Mount the wheel, lower the vehicle, and perform a final torque check on all fasteners
- Test drive: Verify that vibration, clicking, and other symptoms have been eliminated
Safety reminder: Never work under a vehicle supported only by a jack. Always use properly rated jack stands and wheel chocks. Torque specifications are critical for axle fasteners—use a torque wrench to ensure correct clamping force.
Frequently asked questions
Does the APDTY 143854 fit SRT8 models?
No. This axle shaft assembly does not fit Dodge Charger, Challenger, or Chrysler 300 SRT8 models. SRT8 variants require different axle specifications due to their high-performance drivetrain.
Is this axle for the left or right side?
The APDTY 143854 is for the rear left (driver-side) position. If you need the passenger side, verify the correct APDTY part number for rear right fitment.
Can I reuse the old axle nut when installing this CV axle?
It is strongly recommended to use a new axle nut. The factory nut is often a torque-to-yield or prevailing-torque design that loses clamping integrity after removal and may not safely retain the axle on reinstallation.
What causes a CV axle to fail?
CV axles typically fail due to torn or degraded CV boots, which allow dirt and moisture into the joint while letting grease escape. Over time, the exposed joint wears rapidly, leading to clicking, vibration, and eventual fracture. Regular boot inspection can prevent premature failure.
The APDTY 143854 rear left CV axle shaft assembly delivers a direct-fit, OE-replacement solution for 2011-2014 Dodge Charger, Challenger, and Chrysler 300 RWD models experiencing clicking, vibration, or grease leaks from a failing rear axle. Designed to replace OE part numbers 68080381AA, 52123883AA, and 5180493AB, this complete assembly restores smooth, reliable power transfer to the rear left wheel. Verify your vehicle is not an SRT8 variant and confirm fitment on APDTY.com before ordering to ensure compatibility and get back on the road with confidence.
