WTB: 3.73 or 4.10 5-lug 10 bolt rear axle

[bucket]

Sounds like right about $1,000 to have my current axle re-geared with 3.73s and all new bearings/seals/etc, if I pull the axle out of the truck. $1200 or so with the axle in the truck.

It's pricey, but I definitely feel better about having a freshly rebuilt axle that I KNOW is done right and not something that's going to potentially fail next week because it's worn out.

I think I need to get into the business to afford all the things I want to do to this truck...and this one isn't even being restored!

I'd do something about the trans before dropping $1200 on a gear swap and axle rebuild. If it's not abused, just about any rear axle should be good for 300-400K.

Yeah, I need to mull it over. I think part of me just likes shiny new parts, even if used will do.

Anyone know if the front carrier and gears from a 78 K10 10-bolt would work in a 10-bolt rear?

It supposed to. If you look up locker carriers, same gears, same carrier part #. That's why I'm not using the Detroit Locker out of that Burb's rear end. I figured I'm going with the 14B Full float 4.10 or 4.56, then I'll put that Detroit Locker in the front axle and convert it to 8 Lug. Then the other truck, I'll use the ARB Air Locker in the front, and a 14B FF in the rear. That's the plany anyway if it ever gets done, and what I'll live with until I get a D60.

Now heyyyyyyyyy WAIT. You asked for Carrier and Gears. Gears are different Front and Rear Right?? You'd need reverse cut for Front end or you'd be putting all your torque on your Coast side of the gears where they are weak and probably break them. This is why you don't do burnouts in Reverse. So I'm farily certain the carriers will work, but the gears, NO.

Nope, they are the same. That's why some folks prefer the ford front d60 over the GM d60, the ford has a high pinion and reverse cut gears. So it's stronger and the pinion/front shaft are up higher out of harm's way.

Well OK, giving it more thought now, I guess you'd be right, and NO you wouldn't be driving forward on the Coast side of the gear. Think about rotation of the diriveshafts. So reverse cut is only needed when the pinion gear is ABOVE the the ring gear center.

Makes me wonder how dual drive axles are setup in that regard....

Works the same exact way. Only difference in a 2 speed axle is that it has teeth also on the inside of the ring gear, with a set of planetaries inside the ring gear. When LOW is NOT activated it just like your rear end in the Burb. When hit a switch and it engages the planetary clutch, then it reduces the axles turning in relation to the ring gear. Usually cuts it down by 1/3 for low range. But, there is NO difference in the ring and pinion. Still just one ring and pinion, just has a plantetary gear reduction within the same ring and pinion is all. Very similar to Planets on an Auto Trans. But although it's not alike, it's the same exact principle.
