1/2 vs 3/4 ton differences?

[firefighter184]

I searched a while, but couldnt find a solid answer. Sooooooo....

Exactly what, besides 8 lugs vs. 6 lugs, is the difference between 1/2 ton and 3/4 ton front 10 bolts? More splines? Thicker tubes? Are the pumpkins the same? Brakes?

I ended up selling the 14bolts I had, to raise money for my motor fix. Now, I have a guy wanting to sell me a six lug 14b SF, with 4.10s. I have an 8 lug 10 bolt in the driveway. If I were to swap the ring/pinion and lock-rite into my 6 lug? Would it work? Why should I not do this? I have help, so labor will be next to nothing. Just looking for some ideas. Thanks gang!

I think it would be easier to swap the 6 lug outers to the 8 lug axle, if the 8 lug axle is the one with the gears and locker you want to use.

The axle housing and differential is the same.

Rotor's, not sure about calipers. Pumpkin, axle shafts, & tubes all the same between 1/2 & 3/4.

You could swap everything from the knuckles out off of your 6 lugger onto the 8lugger. It would be alot easier and you wouldn't have to deal with setting up gears!


Actually, if memory serves me correctly... The 10 bolts all used the 2nd design, big bearing, spindles. So you could just swap you rotors, hubs, and caliper brackets... THe knuckles will be the same as well as the axleshaft stubs and lockouts..

Exactly! This would be much easier than swapping gears.

Guess I'll be learnin me some axles tricks in a week or two...

me too

Just do it. All the parts should swap over between 10 bolt fronts. If they are both 10 bolt fronts the are basically identical except for the brake backing plates and hub and rotor assembly.

The knuckles are the same, the calipers are the same, the spindles are the same, the wheel bearings are the same, the locking hubs are the same, and the axleshafts are the same as long as both axles are either 28 or 30 spline.

If you have ever repacked your wheel bearings then you can swap 6-8 lug.

so what would be the cost to do the shafts?

I am not exactly understanding your question. Can you clearify it?

28 spline 10 bolts (1/2 ton or 3/4 ton) are the earlier versions available from about 79-88. The 30 spline 10 bolt (either) are the later versions from 88ish-91.

As long as the axleshafts are the same spline count between his 1/2 and 3/4 ton he can swap shafts or use them as spares and also swap the locker.

The 8-lug 10b has the 12.5" rotors vs the 11" on the 1/2 10b.

If you like your current 1/2 wheels and tires I'd say stay 6 lug. If you have been dreaming of new wheels them convert to 8-lug.

I believe the 6 lug axles for the 14b rear are $90 each. You'd need new drum brakes also. If you want rear disks now might be a good time to do that also. It is more expensive to do rear disk on a 14bsf (maybe $400) that a 14ff (I spent $200) so you might want to consider that as well.

The center sections and axles are the same on the 10b fronts. I am not sure about the axle tube thickness, but I believe that is the same also.
