Last week I rebuilt the torque tube assembly by using this Technical Article and Deve’s website. Both of these resources are excellent and between the two I took the brave step of attempting this. Whitelightening: believe me when I say if I can do it - you can too. Not sure if I would have attempted this rebuild without SWEET’s good work.
Bout’ the only thing I would add is the front bearing lock ring can be tricky to slip into place. I took some extra time and ensured this ring was smooth around the outside edge, and I ensured the same for the torque tube. A very light coat of white grease on these two mating surfaces helped to let this ring slide into place with light taps on the pinion gear.
