Truck is a 1990 w. 22re. Should be 4:10 gears and the 7.5 rear diff.
I noticed diff fluid leaking from the pinion and the housing area, so I decided to re-do the carrier seal with FIPG and get a new oil seal for the pinion. I had a new seal already in when I started pulling pieces of rubber off the pinion. So I decided to wreck the new seal and check a bit further. Pulled it apart down to the front bearing, which looks fine. Ordered new bearing spacer and another seal. FSM says to set pinion pre-load with an old-school looking inch pound torque meter, which I don't have. I have a torque wrench that you set and it clicks. Is there a way to set the pre-load properly without that little torque device? Well enough that I don't blow the diff far out in the bush? I want it to last about another 20000 k while I look for axle upgrades. I did a search on here and read some of the ZUK threads. Any tricks beyond the FSM would be useful.
