Torn rear axle — logbook Toyota Land Cruiser Prado 1995

In general, we went hunting, which will be written a little later. the trip turned out to be just very exciting, the water was higher than the roof, after I came home after driving for a couple of days I heard some strange sound that came from the rear axle, similar to when the crosses are unfolding on the cardan, removing and checking the cardan did not lead to anything, removed the gearbox and saw. that one tooth is missing on the main pair, and 2 more are thoroughly eaten up, it’s strange that there was no rumble beforehand, it turned out that I chtoli broke it in the city, I didn’t prescribe coke to the car, in short, everything turned out somehow strange. rear axle oil was normal.
