I don't have a lot of real world experience in this so I hope a few experienced members will chime in and confirm that my plan for moving forward makes sense and if not, I would love hear other suggestions / recommendations. This is all for my 82' FJ40.
I pulled the 3rd members out of the front and rear axles and hoped to install speedi-sleeves and new pinion seals to stop oil leaks at the pinions. After pulling the the 3rd members, I torqued the pinion nut to 170Ft lbs per the FSM and tested the overall pinion preload. With the carriers in, the preload was only 2 inch lbs max were the FSM says it should be no less than 11.3 inch lbs. The pinions do not have crush sleeves, they use shims. Is it possible that the pinion bearings are just that worn that they have eliminated the preload? Unless more experienced members think I should take a different direction, my plan is to buy a gear splitter and change out the pinion bearings/races. This should bring everything back in spec., correct? I guess another option might be to remove the small pinion shim (measures 0.018") and see what pinion preload number I get but that seems like a cheap option that will eventually bite me in the asx. Below are pictures of the bearing races and the yokes. Based on these races can you tell if the the bearing / races are in dire need of replacing?
I am very grateful for your thoughts / opinions. Thank you!
