Learn step-by-step how to replace Redcat Part 70507, the rear axle truss for CAMO TT PRO and CAMO X4 PRO trucks, with practical tips to avoid common mistakes.

Quick Answer

Replace Redcat Part 70507, the rear axle truss, by removing the old truss, aligning the new one, and securing it with the correct hardware. This part fits CAMO TT PRO and CAMO X4 PRO models.

Why the Rear Axle Truss Matters

The rear axle truss on your Redcat CAMO truck provides structural support to the rear drivetrain, helping maintain alignment and smooth operation. Over time, impacts or stress can bend or crack it, leading to handling issues or drivetrain wear.

Replacing Part 70507 restores that support and prevents further damage. It's a straightforward job that you can do at home with basic tools.

Step-by-Step Replacement Guide

Gather Tools and Safety Gear: You'll need a 2.0mm hex driver, a 2.5mm hex driver, a small flathead screwdriver, and safety glasses. Remove the battery from the truck before starting. Always disconnect the battery to prevent accidental startup.
Remove the Rear Wheels and Tires: Use the appropriate hex driver to remove the wheel nuts and pull off the rear wheels. Set them aside in a safe place. Keep the wheel nuts in a small container so they don't get lost.
Access the Rear Axle Truss: The truss is located on the rear axle housing. Use the flathead screwdriver to gently pry off any clips or covers that obscure it. Don't force anything—if it won't budge, check for hidden screws.
Remove the Old Truss: Using the 2.0mm hex driver, remove the screws holding the old truss in place. Carefully lift it off the axle, noting how it sits. Take a photo before removal to remember the orientation.
Install the New Truss: Position the new truss (Part 70507) in the same orientation as the old one. Align the screw holes and hand-tighten the screws, then tighten them snugly with the hex driver. Don't overtighten—strip the threads and you'll need a new axle housing.
Reassemble and Test: Reattach any covers or clips, then remount the rear wheels and tighten the wheel nuts. Reconnect the battery and test drive slowly to ensure everything feels solid. Listen for unusual noises—if you hear grinding, recheck the truss alignment.
