The upper control arm (also called the upper wishbone or A-arm) is a critical suspension component that connects the steering knuckle to the frame. Its primary functions include:

• Steering Geometry: Maintains the correct wheel alignment angles (camber, caster, and kingpin inclination) for stable steering and handling
• Suspension Movement: Allows the wheel to move up and down relative to the frame while maintaining proper geometry throughout the suspension travel
• Load Distribution: Distributes braking, cornering, and vertical forces from the wheel/tire assembly to the frame
• Stability: Works in conjunction with the lower control arm to keep wheels perpendicular to the ground during acceleration, braking, and turning
• Bushings & Joints: Integrated ball joints and rubber bushings allow controlled movement while dampening vibration and noise from the road

A worn or damaged upper control arm compromises steering feel, wheel alignment, and tire wear patterns.

Common symptoms of a failing or damaged upper control arm on a Tesla Model S include:

• Clunking or knocking sounds from the front suspension when driving over bumps or turning
• Uneven or premature tire wear, especially on the inner or outer edge of the tire
• Steering wheel vibration or shimmy, particularly noticeable at highway speeds
• Loose or sloppy steering feel with delayed response to steering input
• Vehicle pulling to one side during braking or acceleration
• Unstable or wandering feel when driving over rough roads
• Excessive nose dive during braking or squat during acceleration
• Visible play or movement at the ball joint area when the vehicle is lifted and the wheel is grabbed and moved

If any of these symptoms are present, have the suspension inspected by a qualified technician before replacing components.

Self-installation is not recommended. Professional installation by a qualified technician or mechanic is strongly recommended for the following reasons:

• Wheel Alignment Critical: After installation, precise four-wheel alignment is essential to ensure correct steering geometry and even tire wear
• Suspension Safety: Improper installation or torque sequencing can compromise steering and suspension safety
• Specialized Tools: Upper control arm installation typically requires ball joint separation tools and proper support equipment
• Brake System Access: Brake components must often be disconnected or repositioned during installation
• Suspension Inspection: A qualified technician can inspect other suspension components (lower arm, bushings, tie rods) while the vehicle is open
• Warranty Activation: Professional installation is required to validate your 10-Year Extended Warranty

Note: Installation instructions are not included with this product.

Tesla Model S vehicles experience accelerated suspension wear for several reasons:

• High Vehicle Weight: The Model S is significantly heavier than equivalent gas vehicles due to battery pack weight, putting greater stress on suspension components
• Instant Torque: Electric motors deliver full torque instantly from standstill, creating aggressive vertical and lateral loading on the suspension
• Regenerative Braking: Frequent hard regenerative braking cycles put intense stress on suspension bushings and ball joints
• Performance Variants: P85D, P90D, and P100D models with Dual Motor acceleration place even higher demands on the suspension
• Tire Quality: Heavy Model S variants often run summer or performance tires that place high lateral forces on suspension geometry
• Mileage & Age: Bushings and ball joints typically wear out between 80,000 and 150,000 miles depending on driving style and road conditions

Regular suspension inspections and timely component replacement are important maintenance items for high-mileage Tesla Model S vehicles.

Yes — wheel alignment is absolutely essential after upper control arm replacement. The upper control arm directly affects three critical alignment angles:

• Camber: The angle of the wheel relative to vertical when viewed from the front. Incorrect camber causes uneven tire wear and poor steering response
• Caster: The angle of the steering pivot axis when viewed from the side. Affects steering stability and return-to-center feel
• Kingpin Inclination: The inward tilt of the upper ball joint. Affects steering effort and wheel tracking

After installation, your qualified technician should perform a complete four-wheel alignment and road test to verify proper steering feel, handling, and tire wear patterns. Most quality shops include alignment as part of upper control arm service; verify this with your technician before the work begins.

Not necessarily, but it is often recommended:

• Worn Pair: If both control arms are worn, replacing both ensures matched suspension geometry and even tire wear front-to-front
• Single Failure: If only the left arm is worn or damaged, replacing just that component is acceptable. Your technician can inspect the right side to determine if replacement is needed
• Labour Cost Advantage: If both sides require replacement, the technician can perform both replacements in one service appointment, reducing total labour costs
• Alignment Benefit: Replacing both sides simultaneously allows your technician to balance suspension geometry front-to-front perfectly

Consult your qualified technician about whether replacing both upper control arms is advisable for your specific Model S based on its age, mileage, and inspection findings.

This is a high-quality aftermarket replacement part manufactured by D2P Autoparts and engineered to meet or exceed Tesla's OEM (Original Equipment Manufacturer) specifications. It is 100% brand new and designed as a direct replacement for the factory upper control arm on all 2012–2020 Tesla Model S vehicles.

It delivers the same structural integrity, steering geometry, suspension performance, and dimensional accuracy as the original Tesla component — at a more competitive price point than a Tesla genuine part, without compromising on quality or long-term durability and reliability under all driving conditions.

This product includes an Extended Warranty under the following terms:

• 10-Year Extended Warranty: Applies when installed by a fully qualified professional
• Activation: Provide a copy of the garage fitment invoice within 30 days of installation to activate your 10-Year Extended Warranty
• Standard Coverage: If no invoice is submitted within 30 days of purchase, coverage defaults to a standard 1-year warranty
• Coverage Scope: Warranty covers manufacturing and material defects only; labour and additional expenses are excluded

D2P Autoparts stands behind the durability and quality of its products. If you experience any product-related issue within the warranty period, please contact us with your proof of professional installation.

On a Tesla Model S, professional upper control arm replacement typically takes between 2 to 4 hours of labour, depending on the technician's experience and whether additional work (such as lower control arm inspection or suspension component replacement) is performed simultaneously:

• Upper Control Arm Only: 2–3 hours (ball joint separation, arm removal/installation, brake access if required)
• With Wheel Alignment: Add 1–1.5 hours (full four-wheel alignment is strongly recommended after installation)
• With Suspension Inspection: Add 0.5–1 hour (inspection of lower arm, tie rods, bushings, and stabilizer links)
• With Additional Repairs: Add time as needed for any other suspension components found during inspection

Most quality Tesla repair shops estimate 3–4 hours total when alignment is included. Consult your technician for a specific time estimate based on your Model S condition.

To confirm 100% compatibility before purchasing, follow these steps:

• Check Vehicle Year: Confirm your Tesla Model S is from 2012 to 2020 (not 2021 or later, which use different suspension architecture)
• Verify Chassis: Confirm your Model S uses Chassis 5YJS (the standard Model S platform for this era)
• Confirm Position: This is a LEFT-HAND (passenger-side) upper control arm. Do not use this for right-side replacement
• Match OE Part Numbers: Compare the part numbers in our specifications (1043965, 1043965-00-A, 1043965-00-B, 52832, 210190) against the number on your original control arm
• Contact Us with Your VIN: Provide your Vehicle Identification Number and our team will confirm exact fitment before you place your order

Checking the OE part number on your existing factory unit is the most reliable method to guarantee correct fitment for your specific Tesla Model S.
