I've searched and found contradictory info on whether or not the front diff needs to be completely pulled. Some say you can just pull the mounting bolts and lower and some say it has to be completely removed. If anybody here has pulled theirs, please enlighten me as to how difficult it is. Probably anyone with a 4WD would be able to shed light on this. I'm trying to decide on whether or not to pull the pan to retrieve a piece of my dipstick tube that fell into the pan when I was trying to replace it. I'll be doing a cam soon, and have an oil pump and timing chain to do also but might just do the cam if the entire job is too much.
