Sealed Power Steering Suspension Parts CM67: Reliable Steering Control

When your vehicle's steering starts feeling loose or unresponsive, it's often a sign that the steering gear or related suspension components need attention. The Sealed Power CM67 is a specific power steering suspension part designed to restore precise handling and reliability. This article covers what the CM67 is, its key features, compatibility considerations, and practical advice for making the right purchase.

Overview of the Sealed Power CM67

The Sealed Power CM67 is a power steering gear—often referred to as a steering box or steering rack, depending on the vehicle application. It is engineered to meet or exceed original equipment (OE) specifications, making it a direct replacement for worn or failing units. Sealed Power, a brand under the Federal-Mogul (now part of Tenneco) umbrella, has a long reputation for manufacturing quality engine and chassis components. The CM67 part number is typically associated with specific truck and SUV applications from the 1990s and early 2000s, though exact fitment varies.

Key Features of the CM67

• Precision Engineering: The CM67 is built to OE tolerances, ensuring a proper fit and consistent steering response. Internal seals and bearings are designed to handle high pressure and temperature fluctuations.
• Durable Construction: The housing is made from robust cast iron or steel, capable of withstanding road vibrations and impact loads. Internal components are coated or treated for corrosion resistance.
• Direct Fit: As a remanufactured or new unit, the CM67 typically includes all necessary mounting hardware and a pre-adjusted sector shaft (for steering boxes). This reduces installation time and guesswork.
• Quality Assurance: Each unit undergoes rigorous testing for internal leaks, pressure regulation, and smooth operation. This helps ensure that the part performs reliably out of the box.

Compatibility and Applications

The Sealed Power CM67 is not a universal part. It is designed for specific vehicles, most commonly full-size SUVs and light trucks from manufacturers like Chevrolet, GMC, Ford, and Dodge. Common applications include:

• Chevrolet Silverado/GMC Sierra (1990–2000 models)
• Chevrolet Suburban/Tahoe (1992–2000)
• Ford F-150/F-250 (1992–1997)
• Dodge Ram 1500/2500 (1994–2001)

Always verify the exact part number against your vehicle's year, make, and model. Sealed Power provides fitment guides, and many online catalogs allow you to input your VIN for confirmation. Using the wrong part can lead to poor steering feel, premature wear, or installation issues.

How to Choose the Right Power Steering Gear

Selecting a replacement steering gear involves more than just picking a part number. Consider the following factors to ensure you get the best component for your needs and budget.

OEM vs. Aftermarket: What to Expect

• OEM (Original Equipment Manufacturer): A genuine factory part offers guaranteed fit and performance but often comes at a premium price. Availability for older vehicles may be limited.
• Sealed Power (Premium Aftermarket): The CM67 sits in the quality aftermarket segment. It is manufactured to OE specs, often from the same suppliers, but sold under the Sealed Power brand. This provides a balance of reliability and cost savings.
• Economy Aftermarket: Lower-cost alternatives may use cheaper materials or have less rigorous testing. They can work initially but may fail sooner, especially under heavy use or towing conditions.

For most drivers, the Sealed Power CM67 offers a solid middle ground. It is suitable for daily driving, light towing, and moderate off-road use. If your vehicle is used for heavy towing or extreme off-roading, you might consider a heavy-duty or performance-oriented gear, but the CM67 is adequate for typical requirements.

Key Specifications to Check

• Steering Ratio: The CM67 typically has a standard ratio (e.g., 14:1 or 16:1). A slower ratio gives more steering effort and precision, while a faster ratio offers quicker response. Match the ratio to your original part unless you want a different feel.
• Input Shaft Type: Power steering gears come with different input shaft configurations (e.g., 3/4-inch or 1-inch, with or without a flat). Ensure compatibility with your steering column.
• Fluid Type: Most power steering systems use ATF (Dexron II/III) or synthetic power steering fluid. The CM67 is designed for the fluid recommended by the vehicle manufacturer. Check your owner's manual.

Installation and Maintenance Tips

Installing a power steering gear is a moderately involved job. While some experienced DIYers can tackle it, others may prefer professional installation to avoid mistakes.

Professional vs. DIY Installation

• DIY Installation: Requires basic mechanical skills, standard tools (socket set, torque wrench, line wrenches), and a helper for alignment. You’ll need to disconnect the pitman arm, steering column, and hydraulic lines. After installation, bleeding the system to remove air is critical. Incorrect bleeding can cause noise or poor steering response.
• Professional Installation: A shop will have the specialized tools and knowledge to ensure correct alignment and torque specs. They can also inspect surrounding components (tie rods, ball joints) for wear. This is recommended if you are not confident in your skills or if the vehicle is used daily.

Post-Installation Care

• Bleed the System: After installing the CM67, fill the reservoir with the correct fluid, start the engine, and turn the wheel lock-to-lock several times while checking fluid level. Repeat until the fluid is clear and free of bubbles.
• Check for Leaks: Inspect all connections (high-pressure and return lines) for seepage after a few days of driving. Tighten fittings if needed, but avoid over-torquing.
• Alignment: A steering gear replacement does not necessarily require a full wheel alignment, but it’s a good time to check toe and other angles. If the steering wheel is off-center after installation, get an alignment to correct it.

Benefits of Replacing with Sealed Power CM67

• Restored Steering Precision: Eliminates play, wandering, and excessive effort.
• Improved Safety: Predictable response helps avoid overcorrection and reduces driver fatigue.
• Cost-Effective: Priced lower than OEM units but with comparable longevity.
• Warranty Coverage: Sealed Power offers a limited warranty (typically one year) against defects, providing peace of mind.

For vehicles that are kept for several more years, investing in a quality part like the CM67 is a smart move. It keeps the steering system reliable without breaking the bank.

Final Recommendation

The Sealed Power CM67 power steering gear is a dependable choice for owners of compatible trucks and SUVs who need a direct replacement for a worn unit. It delivers OEM-grade fit and performance at a reasonable price. To ensure success, confirm your vehicle’s specifications before ordering, and have the part installed by a qualified mechanic unless you have experience with steering systems. After installation, pay attention to fluid levels and steering feel—any abnormalities should be addressed immediately. For most drivers, the CM67 provides the balance of quality and value that makes it a top recommendation for restoring steering confidence.
