Product Details
Upper Ball Joint Ford Ranger
,OEM Replacement Ball Joint
,Verified Fitment Ball Joint
The Front Upper Ball Joint with OEM numbers AB31-34-550-A (AB3134550A) and AB31-34-540-A (AB3134540A) is a direct-fit replacement for Ford Ranger TKE models (2011–2019) and Mazda BT-50. Mounted between the upper control arm and the steering knuckle, this ball joint allows pivoting movement while maintaining suspension geometry and wheel alignment.
Working Principle: The ball joint's ball-and-socket design permits multi-axis rotation between the control arm and knuckle. The tapered stud locks into the knuckle via a nut, while the housing presses into the control arm. A rubber boot retains grease and excludes contaminants. Worn joints develop play, causing steering vagueness and tire wear.
- VERIFIED Fitment Verified: Multiple independent supplier catalogs list AB31-34-550-A as an upper ball joint for Ford Ranger TKE (2011–2019). AB31-34-540-A is listed alongside it for the same applications by one supplier.
- VERIFY Position Clarification: AB31-34-550-A is confirmed as Upper. AB31-34-540-A is listed together with AB31-34-550-A as upper by one source, but independent confirmation of its exact position is limited. Verify position and side (left/right) with supplier before ordering.
- PENDING Material & Durability Data Pending: No public pull-out strength, hardness, or salt spray data. Request from supplier: material certificate, static load test report, salt spray results.
- PENDING Installation Success Rate Pending: No repair order statistics available.
When this ball joint fails or wears, the following symptoms may appear:
- Clunking or popping noise from the front suspension over bumps
- Steering vagueness or wandering
- Uneven or accelerated front tire wear
- Visible play in the ball stud when the wheel is rocked
- Torn or missing dust boot with grease leakage

- 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, while the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs. "long" pushrod variants exist within the MC828264 family.
- Always provide VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
- Support the vehicle and relieve load from the upper control arm.
- Remove the knuckle pinch bolt/nut or press the old joint out (depending on design).
- Clean the control arm bore; inspect for cracks or elongation.
- Press the new joint in squarely — do not hammer. Ensure the snap ring seats fully (if applicable).
- Install the stud into the knuckle; torque to TBC — refer to Ford Ranger TKE service manual.
- Perform front wheel alignment.
Inspect ball joint boots for cracks and check for play every 20,000–30,000 km or if front-end noise develops.
