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.

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?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.
What does this mean? Which is which? That's a measurement to the spring perch?Dont be like me, be able to spot the difference, this measurement is the only really obvious difference in the semi float axles

Just wasn't sure if different axles could be in a 10 bolt.you answered your own question its a 10 bolt. it has 10 bolts. a SF 14 has 14. or am i missing something? you can pull off the cover to check ratio if thats what your after
Point of note: All GMT400s came with drum brakes. Swapping disc brakes in place of drum brakes almost always requires replacing the master cylinder to function properly. If the donor truck's front brakes will swap on, your best bet would be to do a complete brake system swap. The ABS will throw a monkey wrench into that - you'll either have to eliminate it or figure out how to get it to play nice with your truck.I really need to find out more NBS axles... fast!
...I was offered a deal of some leftover parts from 02-06 diesel 8 lug GM trucks. This includes specifically rear axles that I was told are the same 3.73 ratio, 8 lug 14 bolt full float, with g80 and disc brakes.
All GMT400s EXCEPT the rare C3500HD had rear drum brakes. The bigass C3500HD had rear discs.Point of note: All GMT400s came with drum brakes.
Yes! The drum master cylinder has a tiny reservoir, which is not suitable for use with disc calipers. That's totally aside from the ratio of master cylinder bore to caliper piston bore, which may or may not be suitable.Swapping disc brakes in place of drum brakes almost always requires replacing the master cylinder to function properly.
Again, yes. I think there's some ball-joint-stud-hole reaming involved. This site has conversion instructions somewhere.If the donor truck's front brakes will swap on, your best bet would be to do a complete brake system swap.
Use the ABS unit from the donor vehicle?The ABS will throw a monkey wrench into that - you'll either have to eliminate it or figure out how to get it to play nice with your truck.
Maybe. Wouldn't surprise me if the flanges on the ends of the axle housing are somehow different.Can I just swap parts, such as rear disc components onto the earlier 14bolt ff axle?
Sort of.Would the pumpkin swap between the axles assembles if i just wanted to move the g80?
