LEXUS B5L17657G95 Sport Front Steering Gear Rack Pinion

( Manufacturer Part Number: B5L17657G95 ), ( Type: Steering Gear )

Review LEXUS Oem Sport Front Steering Gear Rack Pinion fits RC350 AWD 2016–2017

The **Lexus RC350 Sport AWD Front Steering Gear Rack Pinion (Part Number: B5L17657G95, Models: 2016-2017)** is a precision-engineered component essential for the smooth and responsive handling of this high-performance luxury coupe. Designed to work in tandem with the vehicle s advanced All-Wheel Drive (AWD) system, this steering rack pinion ensures optimal steering precision, minimal play, and reliable durability under the demanding conditions of spirited driving. Crafted from high-grade materials and engineered to Lexus s exacting standards, this part replaces the original pinion gear within the front steering rack assembly, which translates driver inputs into precise wheel movements with near-instantaneous feedback. The pinion s helical gear design reduces noise and vibration, while its robust construction resists wear and deformation, even during aggressive cornering or off-road excursions. Compatible exclusively with the 2016 and 2017 Lexus RC350 Sport AWD models, this aftermarket or OEM replacement part is a critical upgrade for owners seeking to restore lost steering feel, eliminate excessive play, or address wear-related issues that may compromise handling. Whether installed as part of a full steering rack overhaul or as a standalone repair, this pinion ensures that the RC350 s legendary blend of sportiness and sophistication remains intact, delivering the kind of razor-sharp responsiveness that enthusiasts expect from this iconic performance coupe.

### **Pros and Cons of Buying a 2016 2017 Lexus RC350 Sport (B5L17657G95) with AWD and Front Steering Gear Rack/Pinion Issue**

#### **Pros**

1. **Premium Brand and Build Quality**

Lexus is renowned for its reliability, durability, and high-quality materials. The RC350 is a luxury grand tourer with a refined interior, excellent craftsmanship, and a reputation for long-term dependability.

2. **Strong Performance and Handling**

The RC350 features a **3.5L V6 engine (F23 engine)** producing **306 hp and 269 lb-ft of torque**, paired with an **8-speed automatic transmission**. The AWD system enhances traction without sacrificing efficiency, making it capable in various driving conditions.

- The **front steering rack and pinion** (a common point of discussion) is part of the car s precise steering system, which is generally well-engineered for a smooth, responsive feel.

3. **Luxury and Comfort**

The RC350 offers a **spacious, upscale cabin** with premium materials (leather, wood trim, ambient lighting), advanced infotainment (if equipped with the navigation system), and excellent sound insulation, contributing to a quiet, comfortable ride.

4. **Resale Value and Brand Prestige**

Lexus retains strong resale value compared to many competitors. Owning a Lexus carries prestige, and the RC350, in particular, is a well-regarded model in the luxury sedan segment.

5. **AWD Capability**

The **AWD system** provides better stability in adverse weather (snow, rain) and improves off-road capability compared to a FWD-only vehicle. This is a significant advantage in regions with harsh winter conditions.

6. **Low Maintenance Costs (Compared to Competitors)**

Lexus dealerships are known for **lower long-term maintenance costs** than German or Italian luxury brands. The **F23 engine** is robust, and if maintained properly, it can last well beyond 200,000 miles.

7. **Safety Features**

- Pre-Collision System with Pedestrian Detection

- Lane Departure Alert

- Dynamic Radar Cruise Control

- Blind Spot Monitor

- Rear Cross-Traffic Alert

These features enhance safety, especially in heavy traffic.

8. **Reliability of the F23 Engine**

The **3.5L V6 (F23)** is a well-proven engine, used in Lexus models since the early 2000s. It is known for **fewer issues** compared to some competitors' engines of the same era. Common problems (like oil consumption) are rare in well-maintained examples.

9. **Comfortable Long-Distance Driving**

The **suspension tuning** balances comfort and sportiness well, making it suitable for both daily driving and highway cruising. The **quiet cabin** reduces fatigue on long trips.

10. **Aftermarket and Modification Support**

The RC350 has a **dedicated fanbase**, leading to a strong aftermarket for performance upgrades (tuning, exhaust, suspension) and customization options.

#### **Cons**

1. **Front Steering Rack/Pinion Concerns**

- The **steering rack and pinion** in some early 2016 2017 RC350s (and other Lexus models) has been reported to develop **excessive play, whining noises, or fluid leaks** over time.

- If the **power steering fluid is low or contaminated**, it can accelerate wear on the rack and pinion, leading to a **rough, imprecise steering feel**.

- **Replacement cost**: A new steering rack can range from **$1,500 $2,500** (parts labor), depending on the dealer or shop.

- **Prevention**: Regularly checking and topping off **power steering fluid** (every 30,000 50,000 miles) can mitigate this issue.

2. **Higher Purchase Price (Used Market)**

- Even as a used vehicle, the **RC350 retains a premium price** due to its luxury status. You may pay more than comparable sedans (e.g., BMW 5 Series, Audi A6) for similar mileage.

- **AWD models** are slightly more expensive than FWD versions, which could affect budget considerations.

3. **Fuel Efficiency Not Exceptional**

- The **AWD configuration** reduces efficiency compared to FWD models.

- **City**: 18 19 MPG

- **Highway**: 26 28 MPG

- This is **lower than hybrid luxury sedans** (e.g., Lexus ES 350h) but acceptable for a V6 AWD luxury car.

4. **Maintenance Can Be Expensive**

- While Lexus is cheaper than some competitors, **premium parts and labor** (especially at dealerships) can add up.

- **Common maintenance items** (tires, brakes, fluids) will cost more than on a non-luxury vehicle.

5. **Potential Transmission Issues (Less Common but Possible)**

- The **8-speed automatic** is generally reliable, but some early models (including the RC350) have had reports of **rough shifting or delayed engagement** under heavy load.

- **Solution**: A **transmission fluid flush** (every 60,000 100,000 miles) helps prevent this.

6. **Rear Seat Comfort (Limited Legroom)**

- While the **front seats are excellent**, the **rear seats** have **less legroom** compared to larger luxury sedans (e.g., BMW 7 Series, Mercedes E-Class).

- This may be an issue for taller passengers or families.

7. **Resale Depreciation**

- Luxury vehicles **depreciate faster** than non-luxury cars. Even a well-maintained RC350 may not retain value as well as a Toyota Camry or Honda Accord.

8. **AWD System Complexity**

- The **AWD system** adds weight and complexity, which could lead to **higher repair costs** if issues arise (e.g., differential problems, transfer case concerns).

- **Less common than FWD**, so finding a specialist may be harder.

9. **Infotainment System Limitations (If Not Upgraded)**

- The **standard infotainment screen** (if not equipped with navigation) can feel **outdated** compared to newer luxury cars.

- **Bluetooth connectivity** may require manual pairing in some cases.

10. **Sporty Ride Can Be Harsh on Rough Roads**

- The **stiff suspension tuning** provides a **sporty feel** but can make **bumpy roads or potholes** more noticeable than in a softer luxury sedan.

### **Key Considerations Before Purchase**

1. **Steering Rack/Pinion Health**

- **Get a pre-purchase inspection (PPI)** from a **Lexus specialist or independent mechanic**.

- Excessive play in the steering wheel.

- Whining or grinding noises when turning.

- Power steering fluid leaks (under the hood or near the rack).

- **If the rack is failing**, budget for a **replacement** this is the **biggest potential issue** with this model.

2. **Maintenance History**

- **Verify that power steering fluid has been changed regularly** (every 30,000 50,000 miles).

- **Check transmission fluid** (should be fresh, not burnt or dark).

- **Inspect the AWD system** (differential fluid, transfer case fluid).

3. **Mileage and Condition**

- **Ideal range**: **30,000 60,000 miles** (if well-maintained).

- **Avoid high-mileage examples** (above 100,000 miles) unless you re confident in the maintenance records.

- **Look for signs of accident damage** (especially to the front suspension, which affects steering).

4. **Test Drive Focus Areas**

- **Steering feel** (should be precise, not loose or noisy).

- **Transmission shifts** (should be smooth, no hesitation).

- **AWD engagement** (should activate smoothly when needed).

- **Braking and handling** (no unusual vibrations or pulling).

5. **Budget for Potential Repairs**

- **Steering rack replacement**: **$1,500 $2,500**

- **Transmission fluid flush**: **$200 $400**

- **AWD differential service**: **$300 $600**

- **Brake system (pads, rotors)**: **$500 $1,000**

- **Always negotiate the price** to account for these potential costs.
