You throw the diff on the ground and you will need a new diff..
I highly advise not locking the diff on a Nitro..
Excessive drive train wear and possible parts failure will occur..
You have to remember, the Blu Tac method works on Electrics to around 35000rpm or it just turns it into a limited slip as the blu tac wont hold..
That's odd. I know that the Yokomo Nitro Drift Package uses spools front and back. And there are Stage-D spools for the Nitro RS4 3. If you're gonna lock it, lock it correctly. Use some JB Weld. If you don't like it, just buy a new diff. You're using gear diffs, so they're not that expensive.
