when you regear, in addition to the ring and pinion set, is there anything else that you need to get? i know that there are overhaul kits that you can get that include:
"new pinion nut, pinion seal, crush sleeve, pinion shims, carrier shims, ring gear bolts, Locktite, marking compound, brush and gasket and Timken brand pinion and carrier bearings with races."
is this something that is needed when you whenever you re-gear, or only if you are working on an axle with high miles?
thanks
