The included AX0026 upper ball joints share the same application interchange as:

MOOG K80026 — Front Upper

The included AX8607T lower ball joints share the same application interchange as:

MOOG K8607T — Front Lower

Both utilize the corresponding factory-style press-in ball joint configurations and are designed for direct replacement without modification on properly matched factory axle and steering-knuckle applications.

This package provides all four ball joints required to service both sides of the front axle:

(2) Front Upper Ball Joints
(2) Front Lower Ball Joints

Important Super Duty Year Break

For 1999–2022 Ford F-250 and F-350 Super Duty 4WD, this package uses the applicable:

AX0026 / K80026-style Upper
AX8607T / K8607T-style Lower

This package does NOT fit 2023–2026 F-250 / F-350 Super Duty 4WD trucks.

The 2023+ Super Duty platform uses the newer:

AX3049 Upper Ball Joint
AX3050 Lower Ball Joint

Important Application Note

The K80026 upper ball joint is used on additional Ford applications that do not use the K8607T lower ball joint. Those vehicles are intentionally not included in this 4-pack fitment list.

For older Ford trucks, F-450/F-550 models, and Dodge Ram applications, front axle configurations can vary by year, drivetrain, GVWR, and axle specification.

When in doubt, verify that the vehicle calls for both MOOG K80026 upper and MOOG K8607T lower ball joints before ordering.

Description

The Axiom Supply Heavy-Duty Upper & Lower Ball Joint 4-Pack was developed as a complete front ball joint solution for trucks and SUVs utilizing the proven K80026 upper and K8607T lower ball joint combination.

This package combines two AX0026 upper ball joints and two AX8607T lower ball joints, providing all four ball joints required to completely service both sides of the front axle.

The AX0026 upper ball joint is designed around the proven MOOG K80026-style front upper configuration, while the AX8607T lower ball joint utilizes the corresponding MOOG K8607T-style front lower configuration.

Together, these ball joints provide direct OE-style press-in fitment across applicable Ford F-250 and F-350 Super Duty, Ford Excursion, F-450/F-550 Super Duty, older Dana 60-equipped Ford trucks, and Dodge Ram 2500/3500 applications.

At the heart of each ball joint is Axiom's Grade 12.9 Extreme-Duty Ball Stud, paired with a forged steel housing and precision-engineered internal components. This heavy-duty construction is designed to handle increased steering and suspension loads associated with oversized tires, leveling and lift kits, heavy towing, hauling, commercial use, and demanding off-road terrain.

Heavy-duty solid-front-axle trucks place substantial loads on their ball joints. Vehicle weight, steering forces, braking loads, larger tires, and impacts from rough terrain are transferred through these critical suspension components. The Axiom ball joint system is engineered with heavy-duty materials and a robust internal design to maintain smooth articulation and precise steering under demanding conditions.

The self-compensating internal load system helps maintain consistent bearing contact as the joints wear, reducing unwanted movement while supporting precise steering feel and long-term durability.

Whether your truck spends its life towing heavy equipment, working every day, running oversized tires, or tackling difficult terrain, this complete four-piece ball joint package delivers heavy-duty construction, direct-fit installation, full serviceability, and the confidence of Axiom's No-Nonsense Lifetime Warranty.

Maintenance

Apply 2–3 pumps of grease to each ball joint during installation.

For continued performance, service each ball joint with approximately 1–2 pumps of grease every 5,000–7,000 miles, or as required based on vehicle use and operating conditions.

Avoid excessive greasing. Apply only the amount necessary to properly lubricate the joint without overfilling or damaging the dust boot.

Periodically inspect the ball joints and surrounding suspension and steering components, particularly on vehicles equipped with oversized tires, modified suspension, or regularly used for towing, hauling, commercial work, or off-road driving.

Installation

The AX0026 and AX8607T are designed as direct press-in replacements for the corresponding factory-style upper and lower ball joints.

Use a suitable heavy-duty ball joint press and follow the applicable vehicle service procedures during removal and installation.

Ensure each ball joint is installed squarely into the receiving bore and is fully seated and properly retained before final assembly.

When replacing all four ball joints, proper installation sequence is especially important. Improperly installing or preloading the upper and lower ball joints can result in binding, tight steering, or poor steering-wheel return.

Final tightening must follow the proper torque specifications for the supplied ball joint hardware. Always use a calibrated torque wrench for final tightening.

Important: Do not use impact tools for final tightening of ball joint hardware.

AX0026 Upper Ball Joint

The AX0026 shares the same application interchange as MOOG K80026, a press-in front upper ball joint used across applicable Ford and Dodge/Ram heavy-duty solid-front-axle applications.

AX8607T Lower Ball Joint

The AX8607T shares the same application interchange as MOOG K8607T, a press-in front lower ball joint used across the corresponding heavy-duty solid-front-axle applications.

This four-piece package should be used only where the vehicle calls for both the K80026-style upper and K8607T-style lower ball joint combination.

Part numbers are provided for application cross-reference. Because these ball joints span numerous years, models, axle ratings, and front axle configurations, verify the vehicle's model year, drivetrain, front axle, and factory ball joint configuration before ordering.
