Nissan Titan 2005 Rear axle shaft bearing cage nuts and lock washers.
Anyone had an issue to tighten the old bearing cage to 87 ft-lb ?
One of my bolts broke at that force. On a new bearing cage tightening-it just to 50 ft-lb it felt that is stretching to much (possible the old nut stretched?). I tightened the rest of 3 nuts to only 40 ft-lb. My torque wrench it is in spec.
The Frontier documentation is asking only 41 ft-lb, Titan spec is 87 ft-lb .
Any thoughts?

They all use the M226 final drive, but sometime around '11 they dropped the torque on those cage bolts to 57 lbs/ft. I have seen a few break off at the higher torque, but I don't see much real difference between the early and late setups. So I kind of think the engineers rethought it, and I imagine you'd be safe with the 57.

Thank you for your time.
I have aproximative 1/16 longitudinal axle play even with the new bearing and seal installed, it did not changed after bearing and seal change. I'm not sure if this normal and how it can be adjusted?
I just contemplate if there is any correlation between my broken bolt and this amount of axle play?

Very interesting the Frontier recommends replacing the nuts and washer after every disassembly at 41ft-lb. Titan do not recommends that at 87 ft- lb.
The way I understand this axle sort of free slides in the transaxle and bearing house, the bearing cage being the stop. That axle play must be bearing play and bearing sleeve movement in the bearing housing to the seal and the cage. I'm not sure if this is a genius solution or just minimalistic one? It is quit possible this axle play made the seal occasional seepage.

They definitely free-float in the diff, but 1/16" seems like a lot of play. Been a very long while since I did one, but I don't remember the bearings being that sloppy. Was the cup spun in the housing, maybe?

I don't think the bearing seal or sleeve spun in the housing.
The gap between the bearing cage and bearing seal leaves room for longitudinal play along the axle.
I will measure tomorrow exactly with an indicator to know for sure, my estimation is aprox 1/16 (.0625)

I had a chance to measure the above mentioned play, it is .032 inches near the left axle, it feels a lot more with the tire mounted and shacked at 12 and 6 a clock no play at 3 and 9.
With the old (18 years old) bearing and seal it felt the same. No bearing noise or leaking just some seepage seen around the hub with the old set and at the breeder dampness. I figured it is time for a new set of bearings and seal, it looks like i did not fixed anything.
The right axle has .010 inches play with the old (18 years old) bearing and seal. No bearing noise or leaking just some seepage seen around the hub, the same way like the other one. This one I don't think i will change it until bearing noise and some leaking appears not just dampness on the surface.
It is OK to have .032 inch play? Any adjustment can be done?

Honestly, I don't know. Nissan doesn't give any spec that I'm aware of for end play in the axle shafts. I'll just say that 0.032" seems like a lot, tapered bearings don't generally like running with that much slop. The fact that it goes away in certain rotational positions suggests maybe the axle is bent.

Nissan may not specify this detail, in practice a .025 spacer shim i think can do the trick.
Along the axle play in and out is 0.032 inches. This play can be felt in the tire in the 12-6 position only and probably can make the bearing seal to wear out ultimately seep and leak.
If this much play is not from inside the bearing that means that the axle together with the bearing and oil seal moves in the shaft housing. It maybe machined to deep. I assume very tight wont be good ether. A bent axle can complicate the geometry per see.
