Quick answer
To replace the front/rear transverse control arms on a Carrera Profi RC car, remove the old arms by unscrewing the pivot pins, then install the new Carrera replacement arms and secure them without over-tightening.
When to replace transverse control arms
Transverse control arms connect the wheel hub to the chassis and allow the suspension to move up and down. Over time, plastic arms can crack or bend from impacts, causing uneven tire wear or poor handling. If your RC car pulls to one side or the wheels wobble, inspect these arms first.
Choosing the right replacement part
The Carrera Front/Rear Transverse Control Arms (SKU 370410190) are designed specifically for Profi RC vehicles. Using a non-standard arm may alter suspension geometry or require modification. Stick with the genuine replacement to keep the suspension working as intended.
Step-by-step replacement guide
- Remove the wheel and tire: Take off the wheel nut and pull the wheel straight off the axle. This gives you clear access to the control arm pivot points. Common mistake: Forcing the wheel off without removing the nut can damage the axle threads.
- Unscrew the pivot pins: Use a small Phillips screwdriver to remove the screws that hold the control arm to the chassis and the wheel hub. Keep the screws and any washers in a safe place. Checkpoint: Note the orientation of any spacers or washers before removal so you can reinstall them correctly.
- Remove the old control arm: Gently wiggle the old arm free from the pivot points. If it is stuck, use a flathead screwdriver to pry it loose carefully, avoiding damage to the surrounding plastic. Common mistake: Prying too aggressively can crack the chassis mounting tabs.
- Install the new Carrera control arm: Align the new arm with the pivot holes on the chassis and wheel hub. Insert the pivot pins and tighten the screws snugly, but do not overtighten. Checkpoint: The arm should pivot freely without binding. If it feels tight, loosen the screws slightly.
- Reattach the wheel and test: Place the wheel back on the axle and secure it with the nut. Spin the wheel by hand to confirm it rotates freely and the suspension moves smoothly. Final check: Drive the car slowly on a flat surface and listen for clicking or rubbing sounds that indicate a misaligned arm.
