Im running 100k in the front diff. The outputs and gears inside move normally. I dropped the diff in the bluk head with the same settings as the spool (low cam, 8 tension) and it does not spin in the bulk head. Its frozen so much that my 6.5t motor cant even spin it. But as soon as i put the spool back in, it moves just fine.
So again, is there a different diff housing that needs to be used for the front? Or can i just use the rear one since i have the Spec-R in the rear?
You may also want to go to a much stiffer gear oil for the front. 2.5M works for me.
what are u using for 2.5m fluid? Link and description please?
