After I destroyed the spider gears in my rear third on a wheeling trip a few weeks back, I am trying another route. I went ahead and installed a drop-in auto locker, of the Spartan variety, in the rear third of my Land Cruiser.
The Spartan locker went into a spare used rear diff that I purchased here on MUD. It was missing the spider gears, so with the carrier empty, it seemed like the perfect time to try one of these out.
I am interested to experience first hand how it changes the driving characteristics of the vehicle. This truck doesn't see snow, so that potential concern isn't an issue. However, it will be interesting to see if I can get used to the pops and clunks on the road (how much, how bad, etc.), and how the locker improves off road driving.
