Got some free time last night so I went out and popped the broke cover.
Looks like my truck has some missing balls
Here's what was floating around visible through the crack in the cover
So, what did happen to the missing ball bearings? Kind of looks like they are pretty captive in there - would they have slipped out and into the transfer case or broken up? Was some obvious metal grit in there.
Spent a bit of time doing some more eyeballing and it looks like moving everything forward and dropping 2" of the body lift will require me to rework the low tranny hump I added or go back to the high tranny hump. I'm on a very tight budget as this was not a planned project to happen right now so I will probably see if modifying the low hump tranny will allow me to still use my rather new carpet.
I'm thinking I can just move my exhaust hangers forward and avoid having to do anything to the exhaust - not sure on that.
Guess I will start ripping the transfer case out soon, yank the headers, pull the engine crossmember to modify it a bit, then move the engine forward, i.e. open a can of worms!
