XMODSTM Custom RC  
Metal Bearing Upgrade 60-8512  
Tip: For best performance and fit,  
before installing bearings,  
lightly brush each shaft with  
fine sandpaper to remove  
burrs and blemishes.  
Upgrade from standard plastic bushings to metal ball bearings for reduced friction,  
greater precision, and better handling. Before installing, turn off your vehicle and  
controller and then detach the car body.  
Preparing for Your Metal Bearing Upgrade

Loosen and remove each damper screw and detach  
the right and left front and rear dampers.  
Use the lug wrench supplied in your XMODSTM Starter Kit  
to detach the front lug nuts and wheels.  
Tips  
Carefully count and set aside screws while disassembling so you can properly reassemble your car later.  
Bearings can be fitted in place in either direction.  
Be careful that the lead solder joints inside the car do not become detached.  
You may find it useful to remove the antenna from the chassis.
