The 54501-AX000 control arm bushing is a critical suspension component for many Nissan models. This rubber or polyurethane bushing sits at the pivot point of the lower control arm, allowing controlled movement while absorbing road vibrations. If you are experiencing clunking noises, uneven tire wear, or vague steering, a worn 54501-AX000 bushing may be the culprit. This article covers everything you need to know about this partβfitment, symptoms, replacement, and how to choose the right replacement.

What Is the 54501-AX000 Control Arm Bushing?
The 54501-AX000 is the original equipment (OEM) part number for a lower control arm rear bushing used in several Nissan vehicles. It is a rubber bushing pressed into the control arm's rear eyelet. Its job is to isolate the chassis from road shock while allowing the control arm to pivot up and down. Over time, rubber dries out, cracks, and loses elasticity, leading to play in the suspension.
Compatible Nissan Models
This bushing fits a range of Nissan models from the early 2000s through the 2010s. Common applications include:
- Nissan Altima (2002-2006)
- Nissan Maxima (2004-2008)
- Nissan Murano (2003-2007)
- Nissan Quest (2004-2009)
- Nissan Frontier and Xterra (2005-2012, some variants)
- Nissan Pathfinder (2005-2012)
Always verify fitment by checking your vehicle's year, make, and model. The 54501-AX000 bushing is typically used on the front lower control arm, rear position. Some vehicles may require a different bushing for the front position.
Symptoms of a Worn 54501-AX000 Bushing
A failing control arm bushing produces distinct symptoms. If you notice any of these, inspect the bushing immediately.
Clunking or Popping Noises
The most common sign is a clunk or pop when driving over bumps, during braking, or when turning. This indicates excessive play in the bushing.
Vague or Loose Steering
Worn bushings allow the control arm to shift slightly, making the steering feel loose or wandering at highway speeds.
Uneven Tire Wear
When the control arm moves out of its intended position, the wheel alignment changes. This can cause scalloped or uneven tire wear, often on the inner or outer edges.
Vibration in the Steering Wheel
Increased road noise and vibration can transmit through the steering column when bushings lose their damping ability.
Should You Replace Just the Bushing or the Entire Control Arm?
This is a common dilemma. Replacing only the bushing is cheaper but requires pressing out the old bushing and pressing in the new one. If you have the tools (hydraulic press, bushing removal tool), you can save money. However, on older vehicles, the control arm itself may have rust or wear at the ball joint. Many shops recommend replacing the entire control arm assembly because it comes with new bushings and ball joint pre-installed, reducing labor cost.
Pros of Bushing-Only Replacement
- Lower part cost (typically $10β$30 for the bushing)
- Retains original control arm (if in good condition)
Pros of Complete Control Arm Replacement
- New ball joint included
- No need for a press
- Faster installation (bolts in)
- Often only slightly more expensive than bushing labor
How to Replace the 54501-AX000 Bushing
If you choose to replace just the bushing, here is an overview of the process. This is an intermediate-level DIY job. Always consult a service manual for your specific vehicle.
Tools Needed
- Jack and jack stands
- Socket set and wrenches
- Ball joint separator
- Hydraulic press or bushing removal tool
- Torque wrench
Steps
-
Safety First β Secure the vehicle on jack stands. Remove the wheel.
-
Remove the Control Arm β Unbolt the ball joint and the two control arm bolts (front and rear). Carefully pry the control arm free.
-
Press Out the Old Bushing β Using a hydraulic press or bushing press tool, push the old bushing out from the control arm. Apply penetrating oil if rusted.
-
Press In the New Bushing β Lubricate the new 54501-AX000 bushing with soapy water or rubber lubricant. Press it in squarely until it is flush with the control arm.
-
Reinstall the Control Arm β Bolt the control arm back in place, tighten bolts to manufacturer torque specifications. Reattach the ball joint.
-
Lower the Vehicle β Torque all suspension bolts with the vehicle's weight on the ground to avoid bushing preload.
-
Get an Alignment β Replacing control arm bushings changes the suspension geometry. A professional alignment is necessary to prevent tire wear.
OEM vs. Aftermarket Options
You have several choices when buying a 54501-AX000 replacement.
OEM (Original Equipment)
- Made by Nissan or its suppliers
- Guaranteed fit and durability (typically lasts 60,000β100,000 miles)
- More expensive (usually $25β$50 per bushing)
Aftermarket Rubber
- Meets or exceeds OEM specifications
- Lower cost ($10β$20)
- Brands like Moog, Duralast, or ACDelco offer good quality
Polyurethane
- Stiffer material improves handling
- Transmits more road noise and vibration
- Longer lifespan but may squeak
- Recommended for performance-oriented drivers
Final Recommendation
For most Nissan owners, replacing a worn 54501-AX000 bushing with a quality aftermarket rubber bushing (like Moog) is the best balance of cost, comfort, and longevity. If your control arm has high mileage or the ball joint is worn, consider replacing the entire control arm assembly to save labor and ensure all components are fresh. Always confirm fitment using your VIN and consult a professional if you are not comfortable with the repair. A properly functioning control arm bushing is essential for safe handling and tire life.
