Thrust Arm Repair Cost Guide
Front Thrust Arm Replacement
Labor time typically ranges from 1.5 to 2 hours per side. At our rate of $125/hour, labor costs are approximately $187-250 per side. Parts cost varies by vehicle make and model ($80-200 per arm). Total cost for front thrust arm replacement typically ranges from $267-450 per side.
Rear Thrust Arm Replacement
Labor time is generally 1 to 1.5 hours per side. Labor costs at $125/hour come to $125-187 per side. Parts cost varies by vehicle ($75-175 per arm). Total cost for rear thrust arm replacement typically ranges from $200-362 per side.
Additional Considerations:
- Luxury and performance vehicles may require OEM parts, which can increase parts cost
- Additional alignment service is typically required ($89-129)
- Both sides often need replacement at similar intervals
- Rust or seized bolts may increase labor time

Understanding Thrust Arms in Vehicle Suspension
Front Thrust Arm
The front thrust arm, also known as a control arm or radius rod, is a crucial suspension component that connects the front wheel hub assembly to the vehicle's frame or subframe. It helps control the forward and backward movement of the wheel during acceleration and braking, maintaining proper wheel alignment. This component plays a vital role in:
- Absorbing road impacts and vibrations
- Maintaining wheel alignment during acceleration and braking
- Supporting the vehicle's weight distribution
- Ensuring stable handling characteristics
Rear Thrust Arm
The rear thrust arm serves a similar purpose in the rear suspension system. It connects the rear wheel hub or axle to the vehicle's chassis and helps control the longitudinal movement of the rear wheels. Key functions include:
- Preventing axle wind-up during acceleration
- Maintaining proper rear wheel alignment
- Reducing noise and vibration transmission
- Supporting overall vehicle stability
Center Thrust Arm
The center thrust arm, found in some vehicle designs, typically connects the differential or rear axle assembly to the vehicle's frame. This component helps:
- Control differential movement during acceleration and braking
- Maintain proper driveline angles
- Reduce drivetrain vibration
- Improve overall vehicle handling and stability
Note: Regular inspection and maintenance of thrust arms is essential for proper vehicle handling, safety, and performance. Signs of wear or damage should be addressed promptly by a qualified technician.
Common Failure Symptoms of Thrust Arm Bushings and Components
Thrust Arm Failure Signs and Service Guide
Front Thrust Arm
Common Signs of Failure:
- Clunking or knocking noise when going over bumps
- Vibration in the steering wheel
- Vehicle pulling to one side
- Uneven tire wear
- Visible bushing deterioration or cracking
- Excessive play in the thrust arm when checked during inspection
Typical Service Schedule:
- Inspection recommended every 30,000 miles
- Replacement typically needed between 60,000-100,000 miles
- Earlier replacement may be needed in vehicles frequently driven on rough roads
Rear Thrust Arm
Common Signs of Failure:
- Squeaking or creaking sounds from rear suspension
- Unstable handling during cornering
- Rear end wandering on highway
- Abnormal tire wear patterns
- Visible rubber bushing separation
- Metal-to-metal contact points showing wear
Typical Service Schedule:
- Visual inspection recommended during regular maintenance intervals
- Replacement typically needed between 70,000-120,000 miles
- More frequent inspection needed for performance vehicles or those used in harsh conditions
Important Note: These are general guidelines. Actual service intervals may vary based on:
- Vehicle make and model
- Driving conditions
- Driving style
- Climate and road conditions
