How can u tell if u have a sure grip or open diff without taking out the carrier assembly?
Did roadrunners come with open diff ?

jack up the rear end and spin a wheel if the opposite wheel spins in the same direction it's a sure grip... if the opposite wheel spins the opposite direction it's a open rear end.

The only sure way is to pull the diff cover. A sure grip when worn out will act like an open carrier.
