SKF VKJA 5748 CV joint kit

SKF VKJA 5748 CV Joint Kit Overview

The SKF VKJA 5748 is a high‑performance constant‑velocity (CV) joint kit engineered for the front axle of Ford Transit vans, pickups and related chassis. It delivers reliable torque transfer while maintaining smooth operation across a wide range of steering angles.

Key Design Features

• Dual‑Shaft Construction: The kit includes both inner and outer CV joints, ensuring seamless power delivery from the transmission to the wheels.
• Precision Machining: Each component is machined to SKF’s strict tolerances, guaranteeing minimal play and extended service life.
• High‑Strength Bearings: Integrated roller bearings provide robust support for high torque loads typical of commercial van applications.
• Corrosion‑Resistant Coatings: Protective finishes reduce wear in harsh operating environments, such as urban delivery routes or off‑road use.
• Standardized Dimensions: The kit conforms to Ford’s original equipment specifications for the Transit series (model years 2015–2023), making it a direct replacement.

Compatibility and Applications

The VKJA 5748 is specifically designed for:

• Ford Transit – including the standard van, cargo box (Kasten) and bus variants with 2.0 L TDCi engines.
• Front‑axle configurations where the CV joint operates on the wheel side of the drive shaft.
• Both left‑hand and right‑hand steering setups, as the kit is symmetrical.

Installation Procedure

Installing the VKJA 5748 requires a systematic approach to ensure proper alignment and torque settings:

1. Remove Existing Components: Detach the old CV joint, bearing caps, and any retaining rings. Keep track of all fasteners.
2. Clean the Drive Shaft: Thoroughly clean the shaft ends to remove grease, rust, or debris that could affect mating surfaces.
3. Fit the New Inner Joint: Slide the inner CV joint onto the drive shaft, aligning the keyway. Secure with the supplied retaining ring and torque it to SKF’s specification (typically 80 Nm).
4. Install Outer Joint: Mount the outer joint on the wheel side, ensuring proper alignment of the splines. Tighten the outer bearing cap to the specified torque (usually 90 Nm).
5. Check Alignment: Verify that the joint rotates smoothly and that there is no binding or excessive play.
6. Reapply Grease: Apply a thin layer of high‑temperature grease to all bearing surfaces before final assembly.

Maintenance Guidelines

Regular inspection extends the life of the VKJA 5748:

• Visual Checks: Inspect for cracks, wear, or leakage of grease. Any abnormality warrants immediate replacement.
• Torque Verification: Re‑torque bearing caps and retaining rings every 10,000 km or after any major repair.
• Grease Replacement: Replace grease every 20,000 km to maintain lubrication integrity.
• Alignment Checks: Ensure that the steering linkage remains properly aligned; misalignment can cause premature joint wear.

Performance Benefits

The VKJA 5748 delivers several advantages for commercial operators:

• Durability: Designed to withstand high torque loads and frequent steering movements without failure.
• Reduced Noise & Vibration: Precision engineering minimizes NVH (noise, vibration, harshness) levels, improving driver comfort.
• Consistent Power Transfer: Maintains constant velocity across all steering angles, ensuring smooth acceleration and braking.
• Easy Replacement: The kit’s modular nature allows for quick swaps in service bays, reducing downtime.
