I am new to the SC10 4X4. Mine seems to have a clicking, or skipping, sound on heavy acceleration. Slipper is slipping as you can hear the motor rev a bit before it takes off. I pulled my rear Trans apart to check the idler gear and it is fine. Belt seems tight, any tighter I would be afraid of excessive drag. Motor to spur mesh is good. My front clicker is tight, no clicking during braking. Anyone else experience this?
I did not check my front Trans. I checked the rear because I read on this forum for someone having a problem with the rear idler gear. Figured I would give it a look. But I think that will be my next step.
