Upper Control Arm Ball Joint Assembly 8944594651 C8980058750 2904530-T60PR for ISUZU TFS 4x4 D-MAX MU-X X6X8 — OEM-Grade Front Upper Axle, 6-Month Warranty

The Upper Control Arm Ball Joint Assembly covering OEM references 8944594651, C8980058750, and 2904530-T60PR is a front suspension component designed for ISUZU TFS 4x4, D-MAX, MU-X, and X6X8 applications. Its primary function is to connect the steering knuckle to the upper control arm, enabling steering and up-and-down wheel movement while buffering vibration and ensuring smooth vehicle operation.

This ball joint is supplied as an OEM-grade aftermarket part, manufactured in China, and backed by a reference 6-month quality warranty.

• Clunking or popping from the front suspension: A worn ball joint allows the control arm to shift under load, producing a metallic clunk over bumps or during steering.
• Vague or loose steering feel: Excessive play in the ball joint translates to steering free play and reduced directional stability.
• Uneven or accelerated front tire wear: A worn ball joint changes camber and caster angles, causing shoulder wear or cupping.
• Squeaking or creaking over bumps: Loss of internal lubrication or a damaged boot allows contaminants into the ball socket.
• Visible boot damage or grease loss: A torn dust boot is the leading cause of accelerated ball joint wear.
• Wheel alignment that cannot be brought into specification: Excessive ball joint play prevents correct camber/caster adjustment.

Additional related coverage (from cross-reference data): The 8944594651 / C8980058750 reference group also appears in catalogs for ISUZU Rodeo TFS (Light Truck, 2002), D-MAX (II) 2012 →, Honda Passport, Opel/Vauxhall Campo/Frontera, and ISUZU Trooper UBS applications.

Because of the upper/lower position ambiguity in cross-reference data, a physical sample comparison against the original unit is strongly recommended before bulk commitment.

1. Confirm position and fitment first: Compare the replacement ball joint to the original unit. Verify stud taper, thread size, and mounting configuration before disassembly.
2. Safety first: Park on level ground, engage the parking brake, and chock the rear wheels. Support the front corner securely on jack stands.
3. Separate the ball joint: Remove the cotter pin and nut, then use a ball joint separator to press the stud out of the knuckle. Do not hammer on the knuckle or ball joint housing.
4. Remove from control arm: The joint may be press-fit or bolt-in — use the appropriate tool. Note the orientation.
5. Clean mating surfaces: Remove dirt and old thread-locking compound from tapers. A clean taper is essential for a secure fit.
6. Install the new ball joint: Press or bolt into the control arm. Do not grease the taper unless specified.
7. Reconnect and torque: Insert the stud into the knuckle, install the nut, and torque to specification. Install a new cotter pin.
8. Grease (if equipped with a fitting): Until fresh grease purges. Do not over-grease.
9. Professional wheel alignment: Mandatory after installation.
10. Road test: Listen for noise and check for steering pull.

• Inspect ball joint boots at every suspension service or every 20,000–30,000 km.
• Check for play by rocking the raised wheel at 12 and 6 o'clock. Any detectable play warrants replacement.
• Grease at every oil change if a fitting is present.
• Replace in pairs when possible for balanced suspension performance.
