I recently bought a '95 powerstroke 350 automatic with manual drive shifter and every now and then have trouble engaging the 4wd. I don't have the owner's manual and know very little about 4wd. Hope you guys can help a rookie...

Problem I have is sometimes it just doesn't shift into 4wd high or low easily. I found that the more I engage it, it works more freely but still it seems like it gets hung up on something. But my question is should I be in Park when I shift from 2wd to 4wd high to 4wd low, or should I be in neutral. Also, if I have the hubs locked, can I shift from 2wd to 4wd while driving?

Thanks.

 

Hello PSD350, welcome to FTE! take your time and look around. this thread should be in the super duty section or in the 7.3 forum. you can shift into and out of 4wd HI at any speed below 45 mph. however you must be in neutral while at a stop to engage 4 LO. you can even shift into 4 LO with the hubs unlocked, it enables you to back up with a heavy trailer without frying your transmissions. the 4R100 doesnt like it when you are backing up a grade with a load on...
