Is your Peg Perego Outlaw quad making a grinding sound when driving? If so you will need to replace the rear drive motors.. There is 2 motors on the Outlaw quad, 1 motor drives 1st gear and reverse, and the other motor drives 2nd gear..
Peg Perego Polaris Outlaw 12 volt
Peg Perego Corral Green 12 volt
Peg Perego Corral Pink 12 Volt
When replacing the units we do recommend replacing both together.
