Rear end problems

Rear end problems
I have a 2008 Toyota tundra with a 4.7 and I keep dropping the pin that holds my spider gears in into my Pinyan year this will be the second time I’ve replaced does anyone have any tips on how to stop the pain from falling out that holds my spider gears in I keep snapping the little pin that holds that person in

 

My guess is the pin hole is worn allowing the pin to move and causing it to snap flush. The first time it snapped what was going on and where did you get the replacement pin from? Rear ends that keep having problems are often the result of bent housings. The spyders are the weakest part so yours could be worn. There's something that has to much slack somewhere

 

Its a known issue. I dont remember what year they fixed it, but after dropping the pin in my 08, I installed a used diff out of a 2010 and never had anotherissue.
