Choosing the Right 2014-2018 Subaru Forester Control Arm: Key Factors to Consider
Fitment and Mounting Geometry
Fitment is the top concern because a control arm must match the Forester's factory mounting points and suspension geometry. Even small differences in length, bushing offset, or ball-joint taper can change toe and camber behavior, creating steering pull or accelerated tire wear.
When evaluating fitment, confirm the arm is specified for the 2014–2018 Forester and the same suspension position (left/right, upper/lower if applicable). Pay attention to whether the arm is pre-assembled or requires pressing bushings and installing ball joints, as this affects installation complexity and alignment stability.
Bushing Material and Durability
Bushings control how much compliance the control arm allows and directly influence ride quality and NVH. Softer rubber bushings absorb more vibration and can provide a smoother street ride, while polyurethane bushings increase steering precision at the cost of more noise and harsher feedback.
For Forester owners in regions with rough roads or frequent snow, choose bushings rated for abrasion and ozone resistance. Check for molded designs that resist oil contamination and have proven fatigue resistance to avoid premature replacement due to control arm bushing wear.
Ball-Joint Quality and Pre-Assembly
Many front lower control arms integrate a ball joint that bears steering and vertical loads. A high-quality ball joint with proper seals and grease retention will last longer and reduce play that causes alignment issues and loose steering feel.
Pre-assembled arms with pressed-in ball joints and bushings save installation time and reduce the chance of improper assembly. If the arm is not pre-assembled, factor in the extra labor and the need for a press or professional installation to ensure correct seating and torque.
Corrosion Resistance and Coating
Control arms are exposed to road salt, water, and debris, so coatings and metal treatments extend service life. Look for arms with protective finishes, e-coating, or powder coat systems that protect welds and mounting surfaces from rust.
Corrosion-resistant components maintain structural integrity and make future servicing easier because bolts and brackets are less likely to seize. For Forester owners in cold climates, corrosion protection is a particularly important cost-of-ownership consideration.
Alignment Stability and Tolerance
A replacement control arm should preserve factory alignment specs to prevent recurring alignment problems. Arms built with accurate machining tolerances and consistent bushing offsets help maintain toe and camber settings after installation.
If an arm alters suspension geometry, you may need additional alignment adjustments or camber correction components. Consider whether the arm design is intended to be a direct replacement or an adjustable aftermarket piece that requires fine-tuning during alignment.
Ease of Installation and Included Hardware
Installation complexity affects overall cost and downtime. Direct-fit, pre-assembled control arms reduce labor time because they arrive with bushings and ball joints installed. Check whether the product includes new mounting bolts, nuts, or alignment shims; missing hardware increases installation steps.
Also consider whether the design allows a safe, controlled replacement without specialized tools. For DIY owners, parts that minimize the need for a hydraulic press or professional tools are preferable; for shops, pre-assembly saves time and reduces potential warranty issues from improper installation.
Common Control Arm Symptoms on a 2014–2018 Forester
Recognizing symptoms early prevents further suspension damage. Typical signs that a Forester control arm or its components are failing include clunking noises when going over bumps, a wandering steering feel, and uneven tire wear concentrated on the inner or outer shoulder.
You may also notice vibrations at certain speeds or steering shimmy during braking or acceleration. Identifying whether the noise originates from the bushing, ball joint, or mounting hardware helps determine whether a full control arm replacement is necessary or if a repair of a subcomponent could suffice.
- Clunking or popping over bumps indicating worn bushings or ball joint play
- Steering pull to one side or persistent alignment drift after a recent alignment
- Uneven or rapid tire wear along inner or outer edges
- Vibrations or shimmy at highway speeds that reduce after slow speeds
Deciding Between Upper and Lower Front Arms
For the 2014–2018 Forester, determine whether the symptom originates from an upper or lower arm. Upper control arms typically influence camber and minor steering characteristics, while lower arms handle more of the vertical load and wheel location.
When inspecting parts, compare wear patterns on the bushings and ball joints. Replacing only the failed arm can be a cost-effective approach, but if both sides show similar age-related wear it is often wise to replace arms in matched pairs to preserve balanced handling.
- Upper arms: more influence on camber and high-speed stability
- Lower arms: primary load-bearing component affecting toe and vertical wheel control
- Consider paired replacement when wear is bilateral to maintain symmetric handling
Installation Considerations for DIY Owners
If you plan to tackle control arm replacement yourself, prepare the correct tools: jack stands, a torque wrench, breaker bars, and possibly a ball-joint separator or press depending on whether the arm is pre-assembled. Follow torque specs for mounting bolts and recheck after a short test drive.
Also plan for a professional alignment after installation. Even direct-fit arms can shift toe or camber slightly once the suspension settles, so scheduling an alignment ensures the Forester tracks straight and tires wear evenly.
- Verify if the arm is pre-assembled to avoid pressing bushings or ball joints
- Always torque mounting hardware to factory specs and recheck after test driving
- Arrange a post-installation alignment to correct any minor geometry shifts
How Bushing Choices Affect Ride and Noise
Rubber bushings provide more compliance and better noise isolation, making them a sensible choice for owners who prioritize a quiet, comfortable ride. Polyurethane offers firmer handling and more precise steering response but transmits more road noise and vibration into the cabin.
Consider the Forester's typical use. If most driving is on paved roads and comfort is a priority, durable rubber bushings are a balanced choice. For owners who do spirited driving or light off-road work, upgraded bushings may improve steering feel and longevity despite a firmer ride.
- Rubber: quieter, more compliant, good for daily comfort
- Polyurethane: firmer handling, longer wear in abrasive conditions, more NVH
Addressing Alignment Issues After Replacement
Even with exact-fit arms, installations can shift alignment. After changing control arms, a full alignment check and adjustment is necessary to set toe and camber within factory specifications. Driving with incorrect alignment increases tire wear and can mask other suspension faults.
If a replacement arm includes adjustable features, use them to bring geometry back to spec, but keep within the vehicle manufacturer tolerances. Document pre- and post-installation alignment readings to confirm the new component restored correct geometry.
- Always perform a four-wheel alignment after control arm replacement
- Use adjustable arms only to restore factory specs, not to intentionally alter ride height or camber
- Record alignment numbers to verify the effectiveness of the replacement

What are common control arm symptoms on a 2014–2018 Forester?
Common symptoms include clunking over bumps, steering pull, uneven tire wear, and vibrations at certain speeds. These signs often point to worn bushings or ball joint play and warrant inspection.
Can I replace just the control arm bushing instead of the whole arm?
Sometimes bushing replacement is possible, but it often requires a press and careful installation. If the arm or ball joint shows corrosion or play, full control arm replacement is usually the more reliable option.
Will installing new control arms fix alignment issues on my Forester?
New, correct-fit control arms restore the suspension to proper geometry but you should always perform a full alignment afterward. Minor variations during installation can still shift toe or camber and require adjustment.
Do control arms for the Forester come pre-assembled?
Some replacement control arms arrive pre-assembled with bushings and ball joints pressed in, while others do not. Pre-assembled units reduce install time and the need for specialized presses, which can be helpful for DIYers.
How do I tell if a ball joint in the control arm is failing?
A failing ball joint often causes clunking, looseness in steering, or uneven tire wear. During an inspection, look for play by lifting the wheel and checking for vertical or lateral movement at the joint; grease leakage or torn seals are also warning signs.
Should I replace control arms on both sides at once?
Replacing both sides at once is recommended when wear is similar on each side to ensure symmetric handling and consistent steering feel. If one side is new and the other is worn, you may notice uneven response and alignment drift.
Final Verdict
Choose a control arm that preserves the Forester's factory suspension geometry and uses durable bushings and a quality ball joint for long service life. Balance the tradeoff between ride comfort and steering precision when selecting bushing materials, and prefer pre-assembled arms if you want to minimize installation complexity.After replacement, schedule a professional alignment and recheck torque settings after a short break-in period.
