Default Earthquake 3.5 help!

Ok so i was playing with my earthquake and having a blast, everything was fine untill suddnly it seemed like it was revving high and not going very fast, now if that alone was the problem id know its the slipper clutch but i checked and its not, all the power seems to be going to the front wheels, even though im not missing a drive shaft anywhere and the rear diff seems fine, if i spin it by hand the wheels spin together so im wondering why all the power is going to the front wheels?

Check the grub screw on the diff cup at the rear of the tranny. That little set screw holds the cup to the tranny shaft. If it gets loose, the tranny shaft spins inside the cup, but the cup doesn't turn the dogbone.

Hmm, ill have to check that i gave it a quick spin when i took out the rear end but i might have over looked it, but if thats not it then what else? maybe i do need to tighten my slipper clutch?

if you lift the front wheels off the ground and roll the truck for word on the rear wheels does it stand the rear dogbone going to the tranny? if not the rear diff pinion is probably stripped.

no problem lol but yeah it does spin and i think your right about the pinion considering when the truck was on lifted it in my hands gave it a bit of throttle and heard what sounded like a grinding noise, also when i hit the brakes the rear wheels free spun for a bit before stopping although the front wheels stopped with the brakes
