RESOLVEDD CHECK LAST POST! ALWAYS CHECK THE OBVIOUS THINGS FIRST HAHA
2000 dodge ram 4x4
frustrated now lol
first started out as a whinning/vibration at about 30mph+ when in 4 wheel drive
then started popping out of 4 wheel then right back in the got so bad it would do it 5 times in 5 seconds, so i took off the vacuum actuator and seen that the intermediate shaft was chewed up, so i replaced..
U-joints on both sides
still getting the whinnin/humming/vibration but stoped kicking it out of 4 wheel drive, lasted about 2 weeks it started kicking it out again, looked at the shaft, chewed up again, so put a washer right the motor side of the shift fork to engage the callar farther, worked fine for 2 weeks now started to shift back out again. have good vacuum, what could it be??
