1. TRQ Front Right Lower Control Arm with Ball Joint for Infiniti FX35
| Fit Type | Vehicle Specific Fit |
|---|---|
| Auto Part Position | Front Right Lower |
| Material | Cast Iron |
| Adjustable | No |
| Greaseable | No |
This TRQ front right lower control arm replaces the factory unit on 2003–2008 Infiniti FX35 models and arrives pre-assembled with the ball joint and bushings in place. Made from cast iron with a machined ball-joint mounting surface, it is intended as a direct-fit factory-quality replacement to restore steering stability and reduce suspension noise. Typical use is as a like-for-like service part when worn bushings or a failing ball joint cause clunks, wandering steering, or uneven tire wear. Practical benefits include pre-installed components that shorten install time and TRQ’s DIY installation resources for guidance. The part is not adjustable or greaseable, so long-term service requires replacement rather than field greasing, and there are mixed reports on durability in heavy-use cases. Fitment must be verified for the FX35 chassis and alignment is recommended after installation. For a reliability-minded owner seeking a ready-to-bolt replacement, this covers the basics without modification, but those wanting a rebuildable or serviceable arm should consider alternative options.
Best for: Reliability-focused buyers who want a ready-to-install, vehicle-specific replacement that restores factory steering feel and reduces downtime for routine FX35 suspension repairs.
Less Ideal for: Owners who prefer rebuildable or serviceable suspension parts or who plan high‑load or off-road use should consider heavy-duty or greaseable alternatives.
- Vehicle-specific direct-fit for 2003–2008 Infiniti FX35 front right lower position
- Pre-assembled with ball joint and bushings to reduce installation time
- Cast iron construction and machined ball-joint mount for a sturdy, factory-style fit
- Includes manufacturer installation resources and compatibility references
- Ball joint is sealed and not greaseable, so it must be replaced when worn
- Not adjustable for alignment corrections, so a professional alignment is needed after fitting
- Long-term durability varies by use and some users report premature failure in heavy-duty conditions
Verdict A solid, ready-to-bolt factory-style replacement for the FX35 when you need a quick, reliable fix, but not the best choice if you want a serviceable or heavy-duty arm.

Choosing the Right Infiniti FX35 Lower Control Arm: Key Factors to Consider
Fitment and Vehicle-Specific Design
Correct fitment matters because the control arm must match the Infiniti FX35's mounting points and geometry to maintain proper alignment and suspension kinematics. A part designed specifically for the vehicle reduces the risk of unexpected handling changes or the need for fabrication.
Ask whether the arm uses factory-style bushings and ball joint orientations. Even small deviations in bracket location or bushing offset can require additional alignment work and lead to accelerated tire wear. Ensuring direct-fit compatibility simplifies installation and preserves the original suspension geometry.
Material and Corrosion Resistance
The control arm endures road forces and environmental exposure, so material choice affects longevity. Steel arms typically offer high strength, while stamped or cast options vary in stiffness and weight. Protective finishes or powder coating slow corrosion, which is important for longevity in wet or salted-road climates.
Consider whether the manufacturing process and coating will resist rust and cracking over time. A more durable finish and heavier-gauge steel can extend service life and reduce the chance of mid-life failure that leads to sudden handling issues.
Bushing and Ball Joint Quality
Bushings and ball joints are the wear items that determine when a control arm needs replacement. Higher-quality rubber or synthetic bushings provide better vibration isolation and steering precision, while stiffer polyurethane bushings trade comfort for more direct feedback. Ball joints should have tight tolerances and durable seals to resist contamination.
Inspect whether bushings are integrated, replaceable, or pre-pressed. Integrated, well-made components simplify installation, but being able to service or replace bushings separately can be advantageous for long-term maintenance. The choice influences noise, ride comfort, and diagnostic indicators like looseness or clunking.
Installation and Alignment Requirements
Some arms are direct-fit and bolt in with no changes, while others may alter suspension geometry enough to require alignment or extra hardware. Knowing installation needs upfront helps you plan for labor time and whether you can do the job yourself. Pre-drilled holes, included bolts, and clear instructions speed installation.
If an arm affects camber or caster, expect a professional alignment after installation. Consider whether the part is labeled for left or right position and whether instructions recommend torque specs or special tools to ensure safe, secure mounting.
Durability and Warranty Support
Durability factors into lifetime cost and reliability. A good warranty indicates manufacturer confidence and can offset early failures. Look for warranty terms that cover structural defects and premature wear of bushings or ball joints.
Also evaluate documented testing or longevity claims and whether replacement parts or service components are available separately. Longer warranties and clear support channels reduce ownership risk and can be decisive when choosing between similar options.
Noise and Ride Characteristics
Control arm design and the type of bushings used affect NVH, vibration, and steering feel. Softer bushings tend to absorb road harshness but may allow more movement that feels like looseness, while firmer bushings reduce deflection and transmit more road feedback. Noise sources such as creaks, clunks, or squeaks often point to worn bushings or loose ball joints.
Consider the tradeoff you are willing to accept between a quieter ride and crisper steering. If you prioritize comfort, choose an arm with resilient bushings. If you want sharp handling, opt for firmer components while being mindful this can increase transmitted road noise.
FAQ
What are common signs the Infiniti FX35 lower control arm needs replacement?
Common signs include clunking noises over bumps, uneven or accelerated tire wear, and looseness or wandering during steering. You may also notice vibration or a change in vehicle tracking. A visual inspection can reveal torn bushings or excessive ball joint play, which often correspond to these symptoms.
Can I replace a lower control arm myself on an Infiniti FX35?
Many mechanically inclined owners can handle the swap with basic tools, a jack, and stands, but the job often requires breaking loose ball joints and mounting bolts. Because suspension geometry can shift, a professional alignment is usually necessary after installation. If specialized tools or press work are required for bushings, consider professional help.
How long do lower control arms typically last on the Infiniti FX35?
Lifespan varies with driving conditions, climate, and maintenance. In moderate climates and normal driving, arms often last many years, but exposure to road salt, heavy loads, or off-road use can shorten service life. Regular inspection of bushings and ball joints helps catch wear before it leads to failure.
Do new lower control arms come with bushings and ball joints preinstalled?
Some replacement arms are sold as complete assemblies with bushings and ball joints preinstalled, while others require pressing in components. Complete assemblies simplify installation and reduce labor time. Check the part description to confirm whether the arm arrives ready to install or needs additional parts or servicing.
Will replacing the lower control arm fix steering pull or alignment issues?
Replacing a worn or damaged control arm often corrects pull and alignment problems that stem from loose mounting points or degraded bushings. However, alignment issues can have multiple causes, so expect a post-installation alignment to restore precise steering and tire wear. Additional suspension or steering components may also need inspection.
What maintenance helps extend the life of lower control arm components?
Regular inspections for bushing cracks, ball joint play, and corrosion help catch issues early. Keeping underbody components clean and addressing rust promptly extends life. Also avoid excessive impact loads and have wheel alignment checked periodically to reduce uneven stress on suspension parts.
