i thought the same thing, and ive had good luck over the years, but since disconnecting the connector, i havent once waited, or thought i hope the hubs are fully engaged before applying power in 4WD..
ive heard plenty of pops and bangs over the years, and ive had to replace 1 or 2 also... now, im not concerned at all when turning that knob from 2 to 4
it does not seem any different driving in 2WD with everything spinning, no NVH, no noises, no heavy steering..
time will tell, but i dont see a benefit to trucks that are being used in both on/off road situations where you might switch back and forth from 2WD to 4WD for keeping it intact...
thats where most of the IWEs are broken in my opinion...
not fully engaged, partially engaged is what is breaking them...no doubt...
