Review BMW Rear Drive Shaft Il Lwb Thru 12/96 fits 740I 1995–1997

The **BMW 431-58926 Rear Drive Shaft (LWB, 12/96 97, E36 740i)** is a meticulously engineered, high-performance drivetrain component designed exclusively for BMW s iconic **E36 740i** models, specifically those built between **December 1996 and 1997** with the **long-wheelbase (LWB)** configuration. This drive shaft serves as a critical link between the transmission and the rear axle, ensuring seamless power transfer while maintaining optimal alignment and structural integrity under the demanding loads of a high-revving, turbocharged inline-six engine. Crafted from **high-grade, heat-treated steel**, the shaft is precision-machined to BMW s exacting specifications, featuring a **smooth, balanced design** that minimizes vibration and wear, even at elevated RPMs. The **universal joint (U-joint) and constant velocity (CV) joint** assemblies are engineered for durability, utilizing **sealed, grease-filled bearings** that resist corrosion and maintain smooth operation over extended mileage. This drive shaft is fully compatible with the **M54-based 740i** powertrain, including the **turbocharged M62TUB engine**, and is designed to accommodate the unique suspension geometry of the LWB chassis, ensuring proper clearance and articulation. Whether restoring a classic 740i to its original glory or upgrading an existing vehicle for enhanced reliability, this **OEM-replacement drive shaft** delivers the same level of precision and performance that BMW engineers originally intended, making it an essential component for any serious enthusiast seeking to preserve or restore the integrity of their E36.

### **Pros and Cons of Buying a BMW 431 (58926) Rear Drive Shaft (LWB, 12/96 97, 740i)**

#### **Pros**

1. **Classic BMW Driving Experience**

- The M5-derived 740i engine (S62) delivers strong performance with a naturally aspirated 4.4L inline-six, producing around **300 320 hp** (depending on tuning). This provides a satisfying, linear powerband and a traditional BMW sound.

- The rear-wheel-drive layout offers precise handling, especially for a luxury sedan, with a balanced weight distribution and engaging rear-axle response.

2. **Luxury and Comfort**

- The **Long Wheelbase (LWB)** version provides more legroom and a more spacious cabin than the standard 740i, making it more comfortable for taller drivers or passengers.

- High-quality materials, ergonomic controls, and a refined interior (for its time) contribute to a premium feel.

3. **Reliability (Compared to Modern Standards)**

- The **S62 engine** is robust and can last well over **200,000 miles** with proper maintenance, especially if it has had its **valvetrain upgraded** (e.g., forged valves, stronger springs).

- The **5-speed automatic (ZF 5HP24)** is durable, though some units may need attention if not well-maintained.

- The **rear drive shaft** (part of the live axle setup) is simpler than modern multi-link suspensions but can be robust if not abused.

4. **Collectibility and Nostalgia**

- The **740i is a rare and desirable BMW**, especially in LWB form. Its M5 heritage and limited production make it a sought-after classic.

- Enthusiasts appreciate the **retro styling** (1990s BMW design language) and the **sporty yet luxurious** nature of the car.

5. **Potential for Modifications**

- The **S62 engine** is highly tunable, with aftermarket support for **boost kits, turbo upgrades, and forced induction** (though naturally aspirated tuning is more common).

- The **rear-wheel-drive platform** allows for **suspension upgrades, exhaust modifications, and interior customization**, making it a fun project car.

6. **Lower Running Costs (Compared to Modern BMWs)**

- Parts are **cheaper than contemporary BMWs**, and labor costs are lower.

- Fuel efficiency is **better than modern turbocharged BMWs** (around **18 22 MPG combined**), though not as good as diesel alternatives.

---

#### **Cons**

1. **Maintenance and Wear Issues**

- **Valvetrain Wear:** The **S62 s valvetrain (hydraulic lifters, soft valves)** is notorious for **lifter and valve seat wear** after **100,000 150,000 miles**. A **valvetrain rebuild** (replacing lifters, springs, and valves) is often required and can cost **$1,500 $3,000**.

- **Rear Drive Shaft & Axle Issues:** The **live rear axle** can develop **worn bushings, differential issues, or drive shaft cracks** over time. The **rear diff** may need **seal replacements** or **fluid changes**.

- **Suspension Wear:** The **coilovers, control arms, and sway bars** can be soft or worn, requiring **suspension refreshes** ( $1,000 $2,000).

- **Transmission Problems:** The **5-speed auto** can develop **slippage, delayed shifts, or solenoid failures**, requiring **fluid changes and potential rebuilds**.

2. **High Ownership Costs Over Time**

- While parts are cheaper than modern BMWs, **regular maintenance (valvetrain, diff, suspension, brakes)** adds up.

- **Rust** is a concern, especially on **lower control arms, subframes, and wheel wells** inspect thoroughly before buying.

- **Electrical Gremlins:** Older BMWs (pre-2000) can have **faulty sensors, wiring issues, or failing electronics** (e.g., ABS, immobilizer, infotainment).

3. **Reliability Compared to Modern Alternatives**

- If you want **zero maintenance worries**, a **modern AWD BMW (e.g., 550i, 740i xDrive)** or a **Lexus LS 430** would be more reliable.

- The **740i s complexity** (M5-derived drivetrain, hydraulic valvetrain) means **more things can go wrong** than in simpler modern cars.

4. **Driving Experience Limitations**

- **No AWD:** The **RWD-only setup** means poor traction in snow/ice unless you have winter tires.

- **Less Refined Ride:** The **live rear axle** can feel **stiffer and less smooth** than modern multi-link setups, especially on rough roads.

- **No Modern Tech:** **No Apple CarPlay, no advanced safety tech, no hybrid/electric options** this is a **purely mechanical driving experience**.

5. **Market Depreciation & Value Retention**

- While **rare and desirable**, the **740i does not hold value as well as some other BMWs** (e.g., M5s, Z3s, or E39 M3s).

- **Restoration costs** can be high if the car is **rusted out or neglected**.

6. **Finding a Good Example Can Be Difficult**

- **Scams & Bad Examples:** Many **740is have been poorly maintained**, with **hidden rust, valvetrain damage, or transmission issues**. Always **get a pre-purchase inspection (PPI)**.

- **Limited Availability:** Since it s a **rare model**, finding a **well-documented, low-mileage example** can be challenging.

### **Ending Conclusion & Recommendation**

#### **Who Should Buy This Car?**

- **Love classic BMWs** and appreciate the **M5-derived driving dynamics**.

- **Want a project car** with **modification potential** (tuning, suspension upgrades).

- **Prefer RWD over AWD** and don t mind **occasional maintenance**.

- **Enjoy the sound and feel of a naturally aspirated inline-six**.

- **Are prepared for potential valvetrain and rear axle issues** (and have a budget for repairs).

- **Want a rare, collectible car** rather than a daily driver.

#### **Who Should Avoid This Car?**

- **Want a hassle-free, low-maintenance luxury car** (modern BMWs or Lexus/Audi alternatives are better).

- **Live in an area with harsh winters** (RWD struggles in snow/ice).

- **Don t want to spend money on maintenance** (valvetrain, diff, suspension).

- **Prefer modern tech** (infotainment, safety features, hybrid options).

- **Can t find a well-documented, low-mileage example** (risk of hidden problems).

#### **Final Recommendation**

- **Under 100,000 miles** (or **proven valvetrain upgrades** if over 100K).

- **No rust in critical areas** (subframe, control arms, wheel wells).

- **Fresh transmission fluid, diff fluid, and suspension refresh**.

- **A clean service history** (or at least **documentation of major work**).

then it can be a **fantastic investment** both as a **driving experience** and a **potential appreciating asset**.

- **BMW E39 740i (1995 2001)** Similar but slightly more common.

- **Lexus LS 430 (1997 2000)** More reliable, similar luxury.

- **Audi A8 (1994 2002)** Quattro AWD, more refined.

- **Modern BMW 550i xDrive** More reliable, better tech.

**Bottom Line:** The **740i LWB is a fantastic car for the right owner** someone who **loves BMWs, enjoys maintenance, and wants a unique driving experience**. But it s **not for everyone**, especially those seeking a **plug-and-play luxury sedan**. Always **inspect thoroughly, get a PPI, and budget for potential repairs**.
