Dr diff sells the install kits with all the bearings (if you need them) for around 100, good price for the quality. The side bearing adjuster tool you can just get a nut and weld it onto something, only a few in pounds on them.
When I remove them I will check what inch lb's they are set at and put them back the same amount, just like the pinion's (crush sleeve) if my bearings look good :glasses7:
