i bought A Big rock v3 used about 3 weeks ago with some aluminuim shocks and Duratrax Lockup Mt Belted tires, now when i punch the throttle even at 75% power i hear a crunch sounds Then it goes just wondering if this is normal.

As he said, remove the power module and take a look.

Belted tires on these 3S rigs put too much strain on the drivetrain..too heavy. That can lead to diff ring gear or input gear stripped or the spur, etc, so you could find teeth missing or smooth down too low to mesh. Then you could also have the rear diff yoke flexing.

So open the motor power module, rear diff, etc, and take a look (y)
 
Just opened up the power module this is it wondering if it looks normal
