Installing or replacing the steering gear box in a Mitsubishi L300 is a task that requires precision, the right mechanical skills, and most importantly, the proper tools. The MB501185 is the OEM part number for the specific steering gear box designed for the Mitsubishi L300, and ensuring a successful installation means using equipment that guarantees safety and accuracy. This article provides a comprehensive overview of the essential tools required for installing the MB501185 steering gear box in a Mitsubishi L300.
Understanding the MB501185 Steering Gear Box
Before diving into the tool requirements, it’s crucial to understand what the MB501185 steering gear box does. The steering gear box converts the rotational motion of the steering wheel into the linear motion needed to turn the wheels. In vehicles like the Mitsubishi L300, the steering gear box is crucial for ensuring smooth and accurate steering response.
The MB501185 part is specifically designed to fit the Mitsubishi L300, offering compatibility and durability. It’s engineered to meet OEM standards, making it an ideal replacement part for maintaining optimal vehicle performance.
Preparing for the Installation
Installing a new steering gear box such as the MB501185 in a Mitsubishi L300 requires careful preparation. Safety is a top priority, so before you begin, ensure the vehicle is parked on a level surface, the battery is disconnected, and the front wheels are properly chocked. Jack stands should be used to safely elevate and support the front of the vehicle.
Essential Hand Tools
Socket and Ratchet Set
A comprehensive socket and ratchet set is essential when working on the Mitsubishi L300. For MB501185 installation, you’ll need various metric sockets (10mm to 19mm) to remove and tighten bolts and nuts connecting the steering gear box to the chassis and steering column.
Wrenches (Combination and Adjustable)
Combination wrenches are needed to reach areas where a ratchet cannot fit. An adjustable wrench is also handy for turning nuts of various sizes without needing multiple tools.
Torque Wrench
A torque wrench is vital to tighten bolts to the manufacturer’s specifications. Over-tightening or under-tightening can lead to steering performance issues or premature wear of the MB501185 steering gear box.
Steering-Specific Tools
Pitman Arm Puller
To detach the pitman arm from the steering gear box, a pitman arm puller is essential. This tool is designed to remove the arm safely without damaging the steering components.
Tie Rod Separator
This tool helps in detaching the tie rod ends connected to the steering linkage. While some technicians may use a hammer for this step, a tie rod separator ensures a cleaner and safer disconnection.
Steering Wheel Locking Tool
Although not always mandatory, this tool can be used to prevent the steering wheel from rotating while the steering gear box is removed. This maintains alignment and prevents damage to the steering column components.
Vehicle Support Tools
Hydraulic Jack and Jack Stands
You will need a hydraulic floor jack to lift the Mitsubishi L300. Once elevated, secure the vehicle with jack stands rated for its weight to ensure safety while you’re underneath.
Wheel Chocks
Use wheel chocks behind the rear tires to prevent the vehicle from rolling while it is lifted.
Specialty Tools for MB501185 Installation
Line Wrenches
MB501185 installation may involve hydraulic lines if the L300 is equipped with power steering. Line wrenches are necessary to prevent stripping the fittings during removal and installation.
Breaker Bar
For stubborn or corroded bolts, a breaker bar provides the leverage needed to loosen them without causing damage.
Pry Bars
Pry bars can help gently maneuver the old steering gear box out of place and align the new MB501185 unit during installation.
Cleaning and Sealing Tools
Wire Brush and Degreaser
Before installing the MB501185 steering gear box, clean the mounting surface with a wire brush and degreaser to remove grime, rust, or old gasket material that might affect fitment.
Thread Locker and Anti-Seize Compound
Thread locker can be applied to bolts to prevent them from loosening due to vibrations. Anti-seize compound helps with future disassembly, especially for bolts exposed to moisture and road debris.
Electrical Tools (if required)
Some variants of the Mitsubishi L300 might have sensors or electrical connectors integrated into the steering assembly. In this case, the following tools may be useful:
Multimeter
Used for checking electrical continuity and ensuring proper sensor function before reconnecting the battery.
Electrical Tape and Connectors
If any wires need splicing or securing during the installation of the MB501185 steering gear box, having electrical tape and connectors on hand is essential.
Safety Equipment
Mechanic’s Gloves
Protect your hands from sharp edges and hot components during installation.
Safety Glasses
Eye protection is crucial when working under the vehicle or when removing components like the pitman arm.
Work Light
Proper illumination ensures you don’t miss critical steps or fasteners, especially when working in tight engine compartments.
Post-Installation Tools
Power Steering Fluid and Funnel
If the MB501185 steering gear box is connected to a hydraulic power steering system, you’ll need to refill the system with the appropriate fluid using a funnel.
Bleeder Kit
After refilling, the power steering system must be bled to remove air. A power steering bleeder kit makes this process easier and ensures responsive steering.
Alignment Tools or Alignment Rack Access
Once the MB501185 is installed, the steering system will need alignment. While this step is usually done at a workshop with an alignment rack, having basic toe alignment tools can help make preliminary adjustments before driving to a professional service center.
Final Checklist for MB501185 Installation
- All bolts torqued to spec
- Steering gear box properly mounted with no play
- Pitman arm securely fastened
- Hydraulic lines connected without leaks
- Steering wheel centered
- No unusual noises when turning
- Fluid level topped off (for power steering systems)
Conclusion
Installing the MB501185 steering gear box on a Mitsubishi L300 is a manageable task for experienced DIY mechanics or professional technicians, provided the right tools are available. From standard wrenches to specialty steering tools, each plays a vital role in ensuring a safe and effective installation. By preparing with all the necessary equipment mentioned above, you can ensure that your Mitsubishi L300’s steering system operates smoothly, reliably, and safely for the long term.
