Is this box out of one with 4.0?

are they all the same?

What fails in them, just start leaking? What mileage do they start having issues?

My 02 has the cooler and the hydraulic fan, I change the fluid in it yearly.

Great information here. Thanks for the write up. I was planning on doing my seals as well. This will be very helpful.

One thing I will make a note on, I do not believe that bearing belongs on the end of the worm shaft but fell into that position behind the nut when you twisted things too far and had a few bearings fall out. When I disassembled the one I just rebuilt it had a full 24 ball bearings within the worm drive, 12 silver and 12 black. At one point when I was reassembling I had a ball bearing fall within the housing and thought I lost it, it ended up nestled into the end of the worm shaft just like yours, but mine was silver. Considering the ball bearings follow a continuous loop, you need an equal amount of silver and black ball bearings to keep it alternating throughout. Somewhere within your worm drive loop you're missing a black ball bearing and have two silver bearings stacked together
Winner winner chicken dinner! I pulled another box apart last night being extra careful not sping the worm gear out. I pulled the cap off the end of the piston assembly and sure enough, there was no ball at the end. Looks like Ill be pulling my box back apart (good thing its not installed yet). Ive edited the post accordingly. Good looking out!

yes, they are all the same. Usually they just start leaking, occasionally they need adjusted. No certain mileage that im aware of. My original box has 180k on it and I have had no issues.
