spicer 3/4 ton hubs, HD44 being parted out - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Differences I am aware of between 8 lug HD and non HD.
1. lockout style (duh)
2. Bearings are slightly larger on the HD

Differences between the 1/2t and 3/4t
1. Bigger bearings on the HD
2. Larger piston for the caliper on the 3/4t(they interchange)
3. Taller rotor
4. Rumor has it some 3/4t's have thicker tubes, and larger diameter (or maybe thats just some fords)

There were small spindles, and large spindle half and 3/4 ton.

Not trying to steal the thread on you...just trying to figure this out.

so there are 2 sizes of bearings for 3/4t axles????
or are all 3/4t (8-lug) axles considered "HD" with the bigger bearing size????

Thanks

ARKracing, I might be smoking crack on the 3/4ton bearing differences, but 3/4 ton are larger than the 1/2 ton. I think the I.D. is the same however, the half and 3/4 hubs are interchangeable.

W314: Let me separate the shaft from the Tcase, I need to check the CV and make sure its still good. Give me the measurement of your existing shaft, measured center of cap to center of cap compressed, and fully extended to confirm the size I have is the size you need. If the CV checks out, I want $100 for it.

Yeh I knew that the 3/4ts had the bigger bearing than the 1/2 ton and I know that you can put the 3/4 ton spindles on a 1/2 ton axle set up.

I guess I was confused into thinking that there were 2 different types of 3/4t axles

#1. = d44 (3/4ton)
#2. = d44HD (3/4ton)
but they are the same thing and some people just use the "HD" to designate the axle as a 3/4t
