That's what I thought, looks like some of those bolts might be as good as a weld. I thought taking apart the rear diff was tough. It looks like I can access it pretty easily from the outside, just all the pics I've seen online show the engine out. NOT pulling the engine, I'll live with it if that's the case!
Glad to find a new group of Yota experts, even if I am in the wrong group. Maybe I need to pony up and buy a newer rig and then I'll be in the right spot.
