Installing ball joints on RC cars, especially those with pressed-in joints, can be a frustrating experience. Pliers and brute force often prove ineffective, leading to damaged parts and frustration. This guide provides a simple, yet effective, DIY tool for installing RC car ball joints, using common hardware. This method works particularly well for vehicles like the Axial AX-10 crawler but can be adapted for various RC models with pressed-in ball joints.
Building Your Own RC Car Ball Joint Press Tool
This DIY tool requires just a few readily available components:
- M3 Bolt and Nut: It’s recommended to use new hardware, as the process may damage the threads. Avoid using essential components from your RC car kit.
- Large M3 Flat Washer: Choose a washer with a diameter large enough to completely cover the end of the sleeve. This distributes the force evenly.
- Sleeve: A strong, durable sleeve is crucial. Plastic is preferred to prevent marring the RC car parts. The sleeve’s inner diameter (ID) should be at least 5mm, and the outer diameter (OD) should be 8mm or less. A sturdy piece of plastic tubing often found in spare parts bins works perfectly.
Assembling and Using the RC Car Ball Joint Tool
-
Prepare the Ball Joint: For flanged ball joints, insert the bolt through the flange side, following the manufacturer’s instructions. If using non-flanged ball joints, a standard M3 washer can be used on the opposite side of the sleeve.
-
Assemble the Tool: Insert the bolt through the ball joint and then through the corresponding eye on the RC car part. Slide the sleeve onto the opposite side of the eye, followed by the washer and the nut. Tighten the nut finger-tight.
-
Apply Pressure: Ensure the sleeve and the entire tool are aligned perpendicularly to the eye. Use a screwdriver on the bolt head and a nut wrench on the nut to slowly and evenly tighten the press.
-
Listen for the “Pop”: As you tighten, the pressure will increase significantly. You’ll then feel a sudden release of tension as the ball joint pops into place. If the press goes slack without the ball joint seating, check for stripped threads on the bolt or nut.
Conclusion: A Smooth Solution for RC Car Ball Joints
This simple Rc Car Ball Joint Tool provides a controlled and effective method for installing press-fit ball joints, minimizing the risk of damage and frustration. With readily available materials and a straightforward process, this DIY solution can save you time and effort on your next RC car build or repair. This tool proved invaluable for installing link ends as well, demonstrating its versatility for various RC car applications. Say goodbye to struggling with pliers and hello to a more efficient way to work on your RC car’s ball joints.
