I've had enough. My truck just destroyed the rear axle AGAIN. That makes four in the past year that shattered for no reason. What I can't understand is that it never happens during off-roading when you might expect something to break. Everytime it happens during the same simple move. T-junction (Tar road) Come up to stop sign. (Driving like any normal human) Stop. Pull away turning left or right. (Like normal people) Chattering noise coming from the rear axle. CRAAACCK !!!! Another 10 bolt gone. The pinion gear broken in two and crownwheel minus plenty teeth. Set-up was perfect and LS fluid on correct level. What do I do wrong? 'I'm telling you now - FORD 9" L/SLIP going into this truck once and for all' BB454 IF IT DOES NOT HAVE 8 PISTONS - IT'S BROKEN !
