Default Replace pinion yoke.

So when replacing a pinion seal instructions on this forum would have you mark the position of the yoke / nut / pinion shaft so you can torque to the same position.

But if you need to replace the yoke what is required ? or do you need to torque based on measurements ?

I would thnk a new yoke would vary slight from the old one and there would be no mark.
if reusing bearings tighten to used bearing specification i would imagine.
my learnings here with used bearings and seal.

Well the nut came off real easy. I mark the original yoke to test the procedure to tighten.

It took vary little torque to place back to the original markings. I don't have a in lb torque wrench yet but I dont feel any play in the yoke and it turns with similar force as before.

I have heard you need about 160ftlbs torque to get the desired 10-15 rotating torque for used bearings.

I know I didn't use 160 ftlbs or torque ???? Something seems off ?

When i changed seal and retorqued it was beynd 160#.
does not sound right i am betting too loose.
i actually bent the holding bracket with a half inch breaker bar..
Used bearings i think are 5-10.
I went slightly past my mark to get 5inch # but failed to measure initially..
has anyone been there before? Maybe not a crush sleeve?

I didn't need anything like your bars to tighnen the nut to the original position. Did you replace anything other than the seal. I am guess if you have a new crush sleave then those torques are required. I am guessing as the torque required but I placed a bar through the have shaft end
to prevent the diff from moving and used my 1/2 deep socket until I hit the marks. Compared the effort to turn the diff yoke by hand. This diff has 210k km (130k miles). Still the org factory diff the car came with. Other than side yokes still factory original.

Picture before.


picture after.

I only replaced the seal... no other change including bearing and crush sleeve.
i think the inch pound test will reveal.
