So for anyone following my Tcase rebuild, while I have it out I wanted to replace my pinion seals on both diffs as they were both leaking. Did that, but my inexperience with working on diffs got the better of me.
I knew about the crush sleeves but I didn’t ensure I had a full understanding of how everything works before I began which led to what I’m dealing with now.
For the rear. I’m not super concerned about it but here’s where it stands . I worried that I overtightened the nut as I went about a half turn past my mark. Not a crazy amount of torque but enough that I was concerned. Backed it off (I know this doesn’t uncrush the sleeve but I did anyway) and cranked it back on the mark. I got the wheels in the air and generally I have a breakaway of 5-10 inch pounds and a consistent rotational torque of 5 inch pounds. That’s with wheels and brakes still on. However, inconsistent with yoke position, every few rotations or so I’ll get a slightly more difficult turn of 15 inch pounds breakaway followed by th consistent 5 inch pounds rotational torque. No rubbing sounds or roughness very smooth just weirdly higher break away torque when starting occasionally. There’s no up or down in or out play so that’s good. I figure I may be good to run that one as is but the 15 inch pound thing has me wanting confirmation that I didn’t mess something up that I need to address.
My main concern is my front. I replaced the seal and was much more familiarized with the process after the rear scare, but still think I messed it up. I was tightening down the nut, I was about 1/2 of a turn short of my mark (so I thought I was good) and it got fairly tight. I figured it should be getting tight since I was getting close to the mark and I stupidly cranked it attempting to get back to the mark. Got within a 1/4 turn of my mark and realized I shouldn’t be cranking on it that hard, something had to be off. And of course now my front yoke has a breakaway of 65 inch pounds and rotational torque of 45 inch pounds. With wheels tires and brakes still attached. So I’m fairly certain I messed that up.
I guess I just need next necessary steps. I’m not looking to do a full rebuild or anything of either diff, I just want my jeep back on the road. I need to get my crush sleeves sorted and my tcase back in.
Is there a decent how to for just straight swapping and reloading the crush sleeve on my Dana 30 (I think I have a good video for the Dana 35 if I need to)? I searched YouTube and could only really find videos on regearing or full rebuilds of the Dana 30 not really what I want to do.
I understand that there are spacers and/or shims that need to be kept in the same positions as when I pull them out but I am unfamiliar with what these are, how they work, or what all I need to be careful of while disassembling and reassembling.
I’m not afraid of tackling something new. I have plenty of tools and a decent mechanical knowledge base I’ve just never worked on diffs. Any advice would be appreciated.
