Howdy;
I went about replacing my pinion seal on my own today; I was feeling brave. Anyways I marked a white line using an oil based marker to line up the pinion shaft, nut, and yoke for re-installation. So fluid poured out from the diff of course, drenching the shaft. Well the line on the actual shaft disappeared! Not sure how big of a deal this is?
I did line up the nut and yoke perfectly. But I cannot see the mark on the pinion shaft. It had a little bit of play while installing the yoke, is it possible it rotated enough to cause an issue? I did have the parking brake set and the trans in gear, so not much movement should be present if I am correct?
I did count the number of threads showing prior to removing the nut, and have it on with the exact same amount of threads showing again. Should it be okay? I don't have a torque wrench, but I've heard it should be at 15-20lbs. What I do know is that it is tight on there now. When I first removed it, it was so damn loose and with no thread locker.
Cliff notes:
1. Line on pinion shaft erased, but yoke and nut lines are lined up perfectly.
2. Had 4 threads showing on the shaft prior to the dis-assembly, and after installation is also showing exactly 4 threads.
3. Is it possible that the pinion shaft rotated a ton? Curious because I can't see the mark. I did take a picture using flash from above the differential, and there is no mark up there. Parking break was set prior to work, so it shouldn't have rotated much?
Markings prior to removing the nut and seal.
Pic from about to show no marks on the shaft from above
Pic after installation: But can't see a mark on the shaft. Is this important? Should the shaft mark line up to? Or just the yoke and nut? See that tiny little white mark on the bottom of the shaft?? Could that be the remains of the mark? If so, that would mean I'd have to tighten up the nut a TON as it is already very tight. Also, that means the yoke wouldn't line up with the nut and shaft??
Help please
