Review GM TRUCKS Chevy Front Drive Shaft Oem Driveline fits SILVERADO K10 4X4 4WD 1973–1978

The **GM 00326487 Front Drive Shaft (Driveline) for the 1973 1978 Chevrolet Silverado K10 4x4 (4WD)** is a meticulously engineered, full-length front axle assembly designed to deliver unmatched durability and performance in rugged off-road and heavy-duty applications. This driveline component is a direct-fit replacement for the original equipment (OEM) front drive shaft found on these iconic half-ton trucks, ensuring seamless integration with the 250, 262, 292, or 305 cubic inch V8 engines paired with the GM s legendary **TH350, TH400, or Turbo Hydra-Matic 700R4** transmissions. Crafted from high-grade, heat-treated steel, the drive shaft features a robust **slip yoke** at the transmission end, allowing for smooth engagement and disengagement of the 4WD system, while the **constant velocity (CV) joint** at the axle end ensures precise power transfer with minimal vibration, even under extreme angles and loads. The driveline is outfitted with **double-cardan joints** and a reinforced **center bearing**, which absorb shocks from uneven terrain, preventing premature wear and ensuring longevity in demanding conditions. Whether hauling heavy payloads, towing substantial trailers, or navigating rough off-road trails, this drive shaft maintains structural integrity and operational efficiency, making it an essential upgrade for restoring or maintaining the performance of your Silverado K10. Built to withstand the stresses of daily use, this driveline is a testament to GM s engineering prowess from the era, offering a perfect blend of reliability and power for both classic enthusiasts and modern 4WD enthusiasts seeking authenticity.

### **Pros and Cons of Buying a GM 00326487 (1973 1978 Chevy Silverado K10 Front Drive Shaft for 4x4/4WD)**

1. **Compatibility with Classic 4x4 Systems** The GM 00326487 is a front drive shaft designed specifically for the **1973 1978 Chevy K10 pickup trucks**, particularly those with **4WD (four-wheel-drive) configurations**. It is a direct-fit replacement, meaning it will integrate seamlessly with the original drivetrain components, including the transfer case, axle, and steering knuckles.

2. **Durability and Strength** Early 4WD systems on the K10 were built with a focus on off-road capability, and the front drive shaft was engineered to handle heavy loads, rough terrain, and frequent engagement/disengagement of the 4WD system. This makes it a robust component for restoration or repair projects.

3. **Availability of Parts and Support** Since the K10 was a popular truck in its time, parts like this drive shaft are still relatively accessible, especially from specialty aftermarket suppliers, junkyards, or online marketplaces. Additionally, forums and communities dedicated to classic Chevy trucks (such as **Chevy Truck Forum, 4x4Wire, or K10-specific groups**) can provide guidance on installation and troubleshooting.

4. **Restoration Potential** If you are restoring a K10 for off-roading or classic truck shows, a genuine or high-quality aftermarket replacement drive shaft ensures proper functionality and authenticity. Many enthusiasts prioritize original or OEM-style parts to maintain the truck s historical integrity.

5. **Cost-Effective for Repairs** Compared to rebuilding or replacing an entire front axle assembly, a drive shaft replacement is often a more affordable solution. It can save time and labor costs, especially if the shaft itself is the only failing component.

6. **Improved Reliability Over Time** If the original shaft was worn or damaged, replacing it with a new or rebuilt unit can eliminate issues like **excessive play, vibration, or premature failure**, which are common in aging 4WD systems. A properly installed shaft reduces the risk of drivetrain damage during off-roading.

7. **Versatility for Modifications** Some K10 owners upgrade their 4WD systems with aftermarket components (e.g., locking differentials, heavier axles, or custom shafts). A high-quality GM 00326487 or a compatible aftermarket shaft can serve as a solid foundation for such modifications.

1. **Age-Related Wear and Potential Issues**

- **Original shafts** (if sourced from a salvage yard) may have hidden damage, such as **bent yokes, cracked housings, or worn universal joints**, which could lead to premature failure.

- **Universal joints (U-joints)** in older shafts are prone to wear, especially if the truck was used frequently in rough conditions. Replacing U-joints may be necessary if the shaft is sourced secondhand.

- **Grease seals** can leak over time, leading to contamination and accelerated wear.

2. **Limited Aftermarket Options**

- While OEM-style shafts are available, **aftermarket replacements** for the K10 s front drive shaft are not as common as they are for more modern trucks. This means fewer choices in terms of materials (e.g., forged vs. tubular shafts) or performance upgrades.

- Some aftermarket shafts may not fit perfectly due to slight variations in mounting points or transfer case outputs.

3. **Installation Complexity**

- Replacing a front drive shaft on a K10 requires **disconnecting the steering knuckles, removing the axle, and properly aligning the shaft with the transfer case and axle**. This is not a beginner-level repair and may require **specialized tools** (e.g., axle stands, torque wrench, and alignment tools).

- Improper installation can lead to **binding, excessive wear, or even drivetrain damage**, so precision is critical.

4. **Compatibility Concerns with Modified Trucks**

- If the K10 has been **modified with aftermarket transfer cases, axles, or suspension components**, the original GM shaft may not align correctly. Custom fabrication or a different-length shaft may be needed.

- **Longer or shorter shafts** (for lifted trucks or those with custom axles) may not be available off-the-shelf, requiring custom machining.

5. **Cost of New vs. Used**

- A **new or rebuilt GM 00326487 shaft** can be expensive, often ranging from **$300 to $600 **, depending on the supplier and condition.

- **Used shafts** from junkyards or private sellers may be cheaper but come with the risk of hidden damage.

- Additional costs may arise if **U-joints, grease fittings, or mounting hardware** need replacement.

6. **Maintenance Requirements**

- Like all 4WD components, the drive shaft requires **regular greasing of U-joints** (every 5,000 10,000 miles or as recommended) to prevent wear.

- **Inspection for cracks, bent yokes, or loose bolts** should be done periodically, especially if the truck is used off-road.

7. **Rarity of Specialized Suppliers**

- Not all auto parts stores carry this specific shaft, and ordering online may involve **long shipping times** or the need to verify compatibility before purchase.

- Some suppliers may sell **universal fit shafts** that claim to work on K10s but may not match perfectly, leading to fitment issues.

### **Conclusion**

The **GM 00326487 front drive shaft (1973 1978 Chevy K10 4WD)** is a **critical and highly desirable part** for restoring or maintaining a classic K10 pickup with four-wheel drive. Its **direct-fit design, durability, and compatibility** make it an excellent choice for enthusiasts who prioritize **authenticity and off-road capability**. However, potential buyers must weigh the **pros against the cons**, particularly regarding **condition, installation difficulty, and long-term maintenance**.

If you are **restoring a K10 for daily driving or light off-roading** and can source a **high-quality, properly inspected shaft**, this part is a **solid investment**. Conversely, if you are on a **tight budget or lack mechanical experience**, a **used shaft from a reputable source** (with U-joint replacement) may be a more practical option.

For **heavy-duty off-roading or custom builds**, consider whether a **new or aftermarket shaft** (if available) offers better durability or if a **custom-fabricated solution** is necessary.

---

### **Recommendation**

- **Purchase a new or rebuilt GM 00326487 shaft** from a **trusted supplier** (e.g., **Rockland Industries, 4x4 Parts Warehouse, or a K10 specialist**) to ensure quality and compatibility.

- **Inspect U-joints and grease fittings** before installation. Replace worn U-joints if necessary.

- **Follow a detailed installation guide** (e.g., from **Haynes Manuals or a trusted YouTube tutorial**) to avoid misalignment.

- **Buy from a junkyard with a good reputation** and **visually inspect the shaft** for cracks, bent yokes, or excessive play in U-joints.

- **Replace U-joints and grease seals** as part of the repair to extend the shaft s lifespan.

- **Consult a mechanic familiar with K10 4WD systems** before installation to confirm fitment.

- **Measure and verify compatibility** with your specific transfer case and axle setup. A **custom-length shaft** may be required.

- **Consider an aftermarket shaft** if available, but be cautious of fitment issues.

- **Budget for additional labor** if professional installation is needed.

- **Prioritize a heavy-duty shaft** (if available) and **upgrade U-joints to high-performance types** (e.g., **Trac-Loc or Lamo**) for longevity.

- **Regularly grease U-joints** and inspect for wear, especially after rough terrain use.

The **GM 00326487 is a worthwhile purchase** for K10 owners who want to **restore or maintain their truck s 4WD system properly**. However, **due diligence in sourcing, inspection, and installation** is essential to avoid costly mistakes. For best results, **opt for a new or high-quality used shaft** and **follow expert installation advice**.
