so im on the hunt for finding drive train noise.
currently i have replaced the wheel joints and rear drive shaft joints. (Replaced because i didn't know the condition and could not grease them + front ones are toast.)
noise still seems to be there. it also seems to have a peak noise at 35mph. and then it doesn't get much louder after that. but road noise might muffle it.
it has the np242 which i changed out the input gear on but did not rebuild it. its hard to tell where the noise is coming from.
i still have the vacuum controlled front axle but had set the shift fork to lock it all the time. i recently unlocked it to check if it was the front driveshaft or output on the transfer case.
noise is still there if coasting in neutral.
im going to be swapping out the front wheel hubs also. not sure if i should check anything else while im down there.
