I am definately a newb with puddin putty (that sounds good doesn't it

) in a diff....I'm used to laying the gears in there then putting the oil in the diff. case, revolving the gears to get the oil placed, then adding more... with putty what would be the best way to pack a diff case??
I'm sure my car will handle much better with running a diff in front, with putty, besides running my spool, but I have never tried it..
