Default Anyone had/have a corally c4 need help!!

Ive got a corally c4. car runs great. However the back wheels have hardly anypower and all the power is at the front wheels. THe back diff seems fine and it does work, but it just doesnt have power when on the ground. Im assumming it needs adjusting? Can this be done without taking it all apart.
How would i do this?
Or is it a possibility the back diff is done for?

if anyone could help that would be great.

Ive tried searching for a manual but couldnt fine one : (

thanks to anyone who can help

Check to see if your rear diff screw has snapped. If it broke it might seem to work while you are holding your car, but when placed on the ground it would slip and hardly run.

I had a c4 in the past.

The two pinions on the axle where the spur is mounted can be too loose.
You can tighten it and check now and then.
You can adjust the friction so it acts like a oneway on the belt.

I made a small hole in the left and the right pinion, where they come together, and then put a small (diff)ball in between so when you press the pinions together there is no more movement because the ball blocks the two pininons.

Hope you understand what I mean, my english is not good enough to explain more

I think from memory the c4 had a center oneway on the shaft in the middle of the car it allowed adjustment to the center oneway. Check and make sure thatthe adjustment nut is tight and is all on the right way.
