I watched that video back when he installed the locker. I didn't think he had power steering on his P500.
My 500 steers hard enough without P/S. Years ago, (1985) i had a old Jeep CJ-7 that had a 232 V6 Buick engine and I got stuck in the snow and popped the front diff. Money was tight so I welded the spider gears up solid. I'd unlock the front hubs to drive it on the road and off road, it took both hands and a buddy to steer it.
I am assuming the torque locker is able to ratchet around turns to some degree but stay locked when you lose traction on one wheel. Those of you who have the Tq/L , can you hear or feel it ratcheting?
