Quick answer
To install Redcat Part 07452, remove the old CVA axle from your RAMPAGE XT, slide in the new steel 10mm axle, and secure it properly. Follow the steps below for a smooth replacement.
Why replace the CVA axle
The Redcat Racing 07452 is a steel 10mm CVA axle designed for the RAMPAGE XT. Over time, axles can bend or wear, especially if you run your truck hard. Replacing a damaged axle restores drivetrain stability and prevents further wear on other parts.
If you're upgrading from a stock plastic axle, the steel construction of the 07452 adds durability, making it a practical upgrade for aggressive driving. However, steel axles are heavier than plastic, which can slightly increase rotating mass—a trade-off worth considering if you prioritize acceleration over toughness.
Installation steps
- Gather tools and safety gear: You'll need a 2mm hex wrench, a 5mm nut driver or socket, and safety glasses. Park your RC on a flat surface and disconnect the battery to prevent accidental motor movement. Always disconnect the battery before working on the drivetrain.
- Remove the wheel and hub nut: Take off the wheel by loosening the hub nut with the 5mm nut driver. Keep the nut and any washers in a safe place—they're easy to lose. Check the hub nut threads for damage before reusing them.
- Extract the old CVA axle: Slide the old axle out of the hub and differential output. If it's stuck, gently tap it with a plastic mallet—never use a metal hammer, which can damage the bearings. Inspect the old axle for wear; if it's bent, check the bearings for damage too.
- Install the new steel axle: Align the new 07452 axle with the differential output and push it through the hub. Make sure it seats fully—you should see equal length on both sides. If the axle doesn't slide in smoothly, don't force it; check for debris or misalignment.
- Reattach the wheel and hub nut: Place the wheel back on, add any washers, and tighten the hub nut snugly. Avoid overtightening—it can strip threads or bind the bearing. Spin the wheel by hand to confirm smooth rotation before reconnecting the battery.
- Test the drivetrain: Reconnect the battery and run the truck slowly on a stand or on the ground. Listen for clicking or grinding, which indicates the axle isn't seated properly. If you hear noise, recheck the axle alignment and hub nut torque.
