i think you mis understood, the car is 4wd, one belt for the front and one for the back(u would know that)
umm, the front one keeps snapping when im using the car, it used to still drive just the rear, but now it wont move far, it will move like not even walking speed, i go to give it the trigger and it just revs?
any ideas

The problem you have is the front belt may be too tight

Look at the rear pulley the one right behind the engine if there is no set screw (grub screw) that is the problem

i had a look then, the pulley behind the motor, it seems to have a screw in it, man the hobby shop loves me, im down the like every week.
the belt is fairly frayed but that cant be it cos it still spins the wheels, aahhh. i dunno i wish i knew more about them, dont rack ur brain too much about it mate, but ur knowledge is appreciated..

so your engine revs but nothing happens if I am correct do this,
go thru your system , first engine drives the clutch, clutch shoes are engaging properly(springs are not to stiff?), pinion to spurs are meshed correctly yes? spurs are driving the main rear shaft which is connected to your belt yes? rear belt is not to loose?? then after that could be your diff is stripped inside??? then after that and highly unlikely check you universals/dogbones. this should find your problem.
cheers.

this is important if your grub screw is not there your main shaft will just spin and wont engage the rear diff.
