The Stupid Axle Questions Thread

[Schurkey]

MY 9.5 G80 is filled with Valvoline 80W-90, with zero friction modifier in the bottle. Rated for "top-off" of positraction differentials, not a full-fill because of the lack of friction modifier.

K1500s easily upgrade both brakes and axle strength when a 9.5" semi-float axle is swapped-in from a 6-lug K2500. Get the correct gear ratio to match the front. Need one conversion U-joint, and four U-bolts. Couldn't be easier. Shouldn't be too expensive.

Trying to figure out what rear end have on my truck since it's an implant. It's already apparent I have the duo servo drum brakes. How can I tell ? I mean my cover is a 10 bolt. I kinda remember it had a G80 before it grenaded. But what about the axles?

Dont be like me, be able to spot the difference, this measurement is the only really obvious difference in the semi float axles

What does this mean? Which is which? That's a measurement to the spring perch?
