Part Identification
Familiarize yourself with the various spare parts included. Refer to the diagram below for visual identification of common components.
Figure 1: Exploded view of various Pxtoys 1/18 RC car spare parts, including front steering knuckles (PX9300-10), pins (P88011), rear hub carriers (PX9300-11), wheel nuts (PX9300-02), and tires (PX9300-21). This diagram illustrates the general components and their relative positions for assembly.
- PX9300-10: Front Steering Knuckle / C-hub
- PX9300-11: Rear Hub Carrier
- P88011: Drive Pins / Axles
- PX9300-02: Wheel Hex Nuts
- PX9300-21: Tires / Wheels
- P88020: Bearings (as shown in Figure 3)
- Steering Wheel Seat: (Refer to Figure 4)
Setup and Installation
Before beginning installation, ensure your RC car is powered off and the battery is disconnected. Use appropriate tools (e.g., small screwdrivers, hex wrenches) for disassembly and assembly.
1. Tire and Wheel Installation (PX9300-21)

- Remove the old wheel nuts (PX9300-02) and carefully detach the worn tires/wheels.
- Ensure the drive pins (P88011) are correctly seated on the axle.
- Align the new tire/wheel (PX9300-21) with the axle and push it onto the drive pin.
- Secure the wheel with a new wheel hex nut (PX9300-02). Tighten firmly but do not overtighten to avoid stripping threads.

2. Steering Knuckle and Hub Carrier Replacement (PX9300-10, PX9300-11)
Figure 4: Four small metal bearings (P88020) and two black plastic steering components (knuckles/hub carriers), crucial for smooth operation of the RC car's steering and wheel rotation.
- Carefully remove the screws and pins holding the old steering knuckles (front) or hub carriers (rear) in place.
- Note the orientation of the old parts before removal.
- Install the new PX9300-10 (front) or PX9300-11 (rear) components, ensuring bearings (P88020) are properly seated within the new parts.
- Re-secure with the original screws and pins. Ensure all moving parts can articulate freely.
3. Steering Wheel Seat Installation

The steering wheel seat is typically part of the remote control transmitter, not the car itself. If this is a replacement part for your transmitter, carefully open the transmitter casing, remove the old seat, and install the new one, ensuring all connections are secure before reassembling the transmitter.
Operating Principles
These spare parts are designed to restore or enhance the functionality of your Pxtoys 1/18 RC car. Proper installation ensures:
- Tires (PX9300-21): Provide traction and shock absorption. Different tire types may offer varying grip on different surfaces.
- Steering Knuckles/Hub Carriers (PX9300-10, PX9300-11): Critical for the vehicle's steering mechanism, allowing wheels to turn and pivot.
- Bearings (P88020): Reduce friction in rotating parts (wheels, axles), leading to smoother operation, increased speed, and longer component life.
- Wheel Nuts (PX9300-02): Secure the wheels to the axles, preventing them from detaching during operation.
- Steering Wheel Seat: A component within the remote control transmitter that houses the steering wheel, facilitating precise control input.
Maintenance
Regular maintenance of your RC car's spare parts will extend their lifespan and maintain performance.
- Cleaning: After each use, especially off-road, clean dirt and debris from tires, wheels, and suspension components. A soft brush and compressed air can be effective.
- Inspection: Periodically check all nuts and screws for tightness. Inspect tires for wear, cracks, or punctures. Examine steering knuckles and hub carriers for signs of stress, cracks, or damage.
- Lubrication: Bearings (P88020) may benefit from light lubrication with RC-specific bearing oil if they become stiff or noisy. Avoid over-lubrication, which can attract dirt.
- Storage: Store spare parts in a clean, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Loose or wobbly wheel | Loose wheel nut (PX9300-02), worn drive pin (P88011), damaged wheel hex. | Tighten wheel nut. Replace drive pin or wheel if damaged. |
| Poor steering response | Damaged steering knuckle (PX9300-10) or hub carrier (PX9300-11), seized bearings (P88020). | Inspect and replace damaged steering components. Clean and lubricate or replace bearings. |
| Excessive noise from wheels | Worn or dirty bearings (P88020). | Clean and lubricate bearings. Replace if noise persists. |
| Tire losing grip or uneven wear | Worn out tire tread, incorrect tire for surface. | Replace tires (PX9300-21). Consider different tire types for specific terrains. |
