The **Ford CK4Z-4602-B Rear Drive Shaft** is a precision-engineered, high-performance drivetrain component designed exclusively for the **2015 through 2019 Ford Transit models**, including the **250, 350, and 150 series**, when equipped with a **4x4 (4WD) configuration**. This drive shaft plays a critical role in transferring torque from the transfer case to the rear axle, ensuring seamless power delivery while maintaining durability under demanding conditions. Crafted from **high-strength, heat-treated steel**, the shaft is built to withstand the rigors of off-road driving, heavy payloads, and extended use in commercial, utility, or recreational applications. Its **sleek, aerodynamic design** minimizes wind resistance and vibration, contributing to a smoother ride while maximizing efficiency. The **universal joint (U-joint) and constant velocity (CV) joint** assemblies are engineered for longevity, featuring **sealed bearings and rubber boots** that protect against dust, moisture, and debris, reducing wear and preventing premature failure. The **balanced construction** of the shaft ensures minimal vibration, enhancing both driver comfort and drivetrain longevity. Whether used in a **cargo van, work truck, or off-road expedition vehicle**, this drive shaft is a **direct-fit replacement** for the original equipment, maintaining factory specifications for a perfect match. Built to meet **Ford s stringent quality standards**, it is an essential component for maintaining optimal performance in **4x4 Transit models**, ensuring reliable power transfer in all driving conditions.
### **Pros and Cons of buying a Ford CK4Z-4602-B (2015 2019 Transit 250/350 Rear Drive Shaft)**
#### **Pros**
1. **Durability and Reliability** The Ford Transit, especially in the 250 and 350 variants, is known for its robust construction and long-lasting drivetrain components. The rear-drive configuration (with the CK4Z-4602-B driveshaft) is particularly favored in commercial and off-road applications due to its strength and ability to handle heavy loads.
2. **High Demand for Parts** As a widely used vehicle in fleets, construction, and agriculture, the Transit s components including driveshafts are readily available. This makes repairs and replacements easier and more cost-effective compared to less common models.
3. **Proven Performance** The 4.5L V8 (in the 350 variant) and 3.7L EcoBoost (in the 250) engines are well-regarded for their power and efficiency. The driveshaft in question is designed to handle the torque output of these engines, making it suitable for towing, hauling, and heavy-duty work.
4. **Compatibility with Aftermarket Upgrades** The Transit s drivetrain is compatible with various aftermarket modifications, such as lift kits, heavy-duty suspension, and performance exhaust systems, which can enhance its capability for specialized tasks.
5. **Resale Value** The Transit retains a strong resale value compared to many commercial vans, especially when well-maintained. A properly serviced driveshaft and drivetrain contribute to this longevity.
6. **Versatility** The rear-drive configuration allows for better weight distribution in certain applications (e.g., towing trailers or heavy loads), reducing strain on the front axle compared to front-wheel-drive or AWD setups.
7. **Ford s Warranty and Support** Depending on the vehicle s history, some parts may still fall under Ford s extended warranty or dealer service plans, providing added peace of mind.

#### **Cons**
1. **Cost of Replacement** While driveshafts are durable, they are not cheap to replace. The CK4Z-4602-B is a specialized part, and labor costs (especially in a shop with experience in commercial vehicles) can add up. Expect to pay **$800 $1,500 ** for parts and labor, depending on location and shop rates.
2. **Potential for Wear in High-Mileage Vehicles** If the Transit has exceeded **200,000 miles** or has been used in rough conditions (off-roading, towing, or poor road surfaces), the driveshaft may show signs of wear, such as:
- **U-joint failure** (common in high-mileage vehicles)
- **Bending or cracking** (from heavy loads or impacts)
- **Fluid leaks** (if the CV joints or constant velocity boots are damaged)
A thorough inspection (including a **road test for vibration or clunks**) is essential before purchasing.
3. **Limited Availability of OEM Parts** While aftermarket driveshafts exist, some buyers prefer **OEM (Original Equipment Manufacturer) parts** for reliability. However, OEM CK4Z-4602-B driveshafts may be harder to source quickly, especially for older models.
4. **Maintenance Requirements** Driveshafts require periodic inspection and lubrication (especially U-joints). Neglecting maintenance can lead to premature failure, which may not be covered under warranty.
5. **Weight and Handling** The Transit, particularly in the 350 variant, is a heavy vehicle. A failing or improperly aligned driveshaft can affect handling, leading to **vibration, clunking noises, or even drivetrain damage** if ignored.
6. **Potential for Counterfeit or Low-Quality Parts** When buying used or aftermarket driveshafts, there s a risk of receiving **substandard or counterfeit parts**. Always verify the source and check for **Ford-approved or reputable aftermarket brands** (e.g., Dana, Spicer, or local commercial vehicle suppliers).
7. **Labor-Intensive Replacement** Replacing a driveshaft in a Transit requires **jacking the vehicle, removing the rear axle, and carefully aligning the new shaft**. This is not a DIY job for most people, adding to the cost.

### **Key Considerations Before Purchase**
1. **Vehicle History** Check for:- **Accident damage** (especially to the rear axle or driveshaft area).
- **Maintenance records** (timing belt, differential fluid, U-joint greasing).
- **Previous owners notes** on drivetrain issues.
2. **Inspection by a Professional** Have a **trusted mechanic specializing in Ford Transits** inspect the driveshaft for:- **Visible cracks or bends**.
- **Excessive play in U-joints**.
- **Fluid leaks from CV joints**.
- **Alignment with the differential and axle**.
3. **Budget for Replacement** If the driveshaft is failing, factor in:- **Part cost** ($500 $1,200 for a new/used OEM or aftermarket shaft).
- **Labor cost** ($300 $800, depending on shop rates).
- **Potential additional repairs** (e.g., differential issues, axle damage).
4. **Alternative Options**
- If the driveshaft is beyond repair, consider whether the **entire rear axle or differential** needs replacement, which could be more costly.
- Weigh the cost of fixing the driveshaft against the **vehicle s overall condition** if the rest of the Transit is in poor shape, it may not be worth the investment.

### **Final Recommendation**
**Buy the CK4Z-4602-B driveshaft (or a Transit with a functional one) if:**You have **verified it is in good condition** through a professional inspection.
The **vehicle has low miles (
You are **prepared for potential future replacement costs** (driveshafts typically last **100,000 200,000 miles** with proper care).
The **overall Transit is reliable** and worth the investment for your intended use (commercial, towing, off-roading, etc.).
**Avoid or proceed with caution if:**The driveshaft shows **visible damage, excessive wear, or leaks**.
The **vehicle has high miles (>200,000) with no maintenance records**.
You **cannot afford a replacement** if failure occurs soon after purchase.
The **rest of the drivetrain (differential, axle, transmission) is neglected**.
#### **Best Approach:**- **For a used driveshaft:** Buy from a **reputable commercial vehicle parts dealer** or a **trusted mechanic** who can guarantee its condition.
- **For a used Transit:** **Prioritize vehicles with full service history** and get a **pre-purchase inspection** focused on the driveshaft and rear axle.
- **For a new driveshaft:** If replacing, **stick to OEM or high-quality aftermarket brands** (e.g., Dana 44, Spicer, or Ford-approved parts).
**Bottom Line:**The **CK4Z-4602-B driveshaft is a solid, durable component** when properly maintained. However, its **replacement cost and potential failure risks** mean it should not be overlooked in a used Transit purchase. If you re confident in the vehicle s condition and budget for repairs, it s a worthwhile part to have in a heavy-duty Transit. If unsure, **prioritize a vehicle with a known good driveshaft** or budget for its replacement upfront.
