It’s been a while but I’m back with another upgrade for my ECX Torment. This time I am going to show how to install the new HD drive shafts, this is great for owners of the brushed versions of the truck.
First I will show the difference in the size of the drive balls, as you can see the left is the new HD vs on the right the original.
Now we need to remove the wheel, camber link, axle nut and pin.
Next we pull the outer axle out of the hub and slide the outer drive out from the inner drive as well.
Remove the pin for the inner shaft, and slide off the inner drive.
Now is a good time to inspect and clean.
Next put the new HD inner drive on the transmission shaft and install the pin.
Next slide the new outer drive in the inner driveshaft , then into the hub, install the outer pin and axle nut and you are finished.
I have tested this new setup and I have to say that the truck is more responsive to my throttle input than it was before, and i think this is due to the extra strength that doesn’t allow as much flex.
So in conclusion, if you have the old drives throw them away and go get the new HD drives, you won’t regret it.
