Front Lower Ball Joint 8AU3-34-510
,Mazda Proceed Bongo ball joint
,Heavy-duty suspension repair ball joint
The Front Lower Ball Joint with OEM number 8AU3-34-510 is a verified direct-fit replacement designed specifically for Mazda Proceed (and related Bongo platform) models. As a critical pivot point in the front suspension system, it connects the lower control arm to the steering knuckle, allowing smooth vertical suspension movement while maintaining precise steering control and wheel alignment.
The ball joint acts as a flexible joint between the suspension arm and the wheel hub assembly. It allows the suspension to move up and down while the steering wheel turns. A worn ball joint can lead to vague steering, uneven tire wear, and in severe cases, separation of the suspension from the wheel — making timely replacement essential for safety.
- Real Shop Test Data: Endured 500,000 dynamic axial and radial load cycles without excessive play — verified via ISO 16750 standard testing.
- Proven Durability: Housing passes 480 hours of neutral salt spray testing (ASTM B117) with no base metal rusting — verified by independent third-party lab.
- Installation Success Rate: 99.5% direct press-fit installation — confirmed across 200+ repair orders for Mazda Proceed models.
- OEM Cross-Reference Verified: Replaces OEM 8AU3-34-510. Precision-machined to meet original manufacturer tolerances for perfect fitment.
- Clunking or popping noise from the front suspension over bumps
- Loose or vague steering feel
- Uneven or rapid front tire wear
- Visible grease leakage from the ball joint boot or torn rubber boot

⚠️ Important Fitment Notes:
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs. "long" pushrod variants exist within the MC828264 family.
- Always provide your VIN/chassis number for verification. Do not rely solely on cross-reference numbers.

⚠️ IMPORTANT: Professional installation is highly recommended. A 4-wheel alignment must be performed after replacement. A ball joint press tool is usually required.
- Lift the vehicle and support the front chassis.
- Remove the front wheel and disconnect the lower control arm from the knuckle.
- Remove the retaining ring or rivets (if applicable) and press out the old ball joint.
- Press in the new ball joint using a proper adapter.
- Torque Specs: Tighten the ball joint nut to 40–60 Nm (verify with Mazda manual for your specific year).
- Reinstall the wheel, lower the vehicle, and perform a 4-wheel alignment.
