Mine arent that cool other then i broke just 2 birfs. First time was my old truck, 1981 longbed locked in the front and rear with 37s. Second one was in my 1986 4runner SAS'd using the 1981 axle/locker/birfs and also running 37s.
First one:
Fordyce, backing uphill, turning right, not on it at all
Second one:
Highlakes in the snow, backing on a slight uphill, straight, idling
