Does anyone know what year that GM made the HD 8 lug rear-end's with 14 bolt, 10.5" ring where the drums were integrated with the hubs(ie: have to remove the axles and inner lock nut in order to remove the drum to change the brake shoes? This is with the full floater and locker.

Many years, don't know the exact year but I think the drum style stopped in 00 and the 01's were HD's and all use disc brakes on the same rear end.
Do you need one or parts or something?

Joey,
No, I have one that I bought from a buddy at work thinking my rear-end was toast and it seemed to be totally different from mine.
My rear-end has the ability to remove the drum to change the brakes without having to remove the axles, and also remove the axles without having to remove the drums.
He thinks it came from an 89 GM 1 ton buit was not sure. Now I have this extremely heavy rolling lump in my driveway. He may have someone to buy it back but I was just wondering what year ir came off of.
I would hate to have one where I had to remove the axles, drums and bearing/seal unit just to change my rear brakes out.
For the most part, It was just a curious question. The only thing its missing is a locker, since it's a full floater, 14 bolt w/ 10.5 ring / 4.10 gears. I was maybe thinking I had to change out the entire rear-end, but ended not needing to do so, therefore I have bought an additional piece of yard art. LOL

I have to pull the axle and then remove the hub assembly to get the drum off. I was thinking only the suburbans had the slide off drums.
What did you pay for the rear axle?

$75.00

Although it is not just the axle as I am so oftenly corrected....;-( I'm not used to the heavy duty trucks so when I say axle, I think it's the whole rear-end(which this one is).
I have been corrected in my statements that with a full floater, the axle is one of the pieces that slide out of the shaft... OK so I'm learning..;-)

Joey you should not have to. ;)

Different years
The year split is '72-88 and 89+. I shall refer to these as "first design" and "second design". Of course, there may be variations. Differences between these years are noted below. Where the difference is known only to apply to certain "types", I shall indicate this. Otherwsie, it is not known whether the differences noted between the years apply to all types or not.

Second design axles have more fins on the center section
First design axles 1984 and earlier use a different pinion straddle bearing than 1985 and later
Second design SRW axles in 1-ton pickup trucks and 3/4 ton Suburbans changed to allow for a slide-off drum (drum can be removed without pressing out the wheel studs). The backside of these hubs is not machined flat to accept a rotor, for example. The hub flange is also further inboard to allow for the thickness of the drum.

My 96 1 ton and my 98 3/4 ton I have now the drums do not slide off, it sucks

Snap a pic.... That will solve the issue and make ti ieasy to tell you wat to do next!!!

BTW: How did you trash a 14-bolt 10.5" FF axle anyway!!!!

For those of you that are tired of pulling axles to do rear brakes on older full floating rears like i am there is a shop called great lakes off road that makes caliper brackets that bolt to the 4 bolt flange on the axle housing. Once you bolt up the brackets you need rotors, calipers, and brake lines from a 75 Chevy 3/4 ton front axle and you should be set, if you want e-brake calipers I'm told 76-78 rear Cadillac Eldorado calipers will work. The UPS driver just dropped off my brackets today. I'm figuring the conversion will cost me about $400 to $500 I will post the out come when I'm done.

Big will,
Snapping a pic would not be a problem, but posting/attaching it will. I tried to use one of my pics for the avatar, but it was way too big to allow it and not sure how to make it fit.
As for trashing the old rear-end, found I did not do so and am too embarassed to say what the problem was with blowing three sets of seals(they were put on backwards by instructions of my neighbor mechanic:mad: )
And yes he is still employeed, just stay away from the CSI waste trucks in the Cincinnati area:lol: .

P.S. I do have rear brakes now too......Yeah.

Dunno who's "correcting" you, but I think you were right in the first place.
The pieces that slide out are more properly (and more descriptively) called "half shafts".:lol:

Now that makes more sense to me.
Thanks, I don't feel so dumb now.

Proper would be axle shaft, half shafts are whats in the front end of an IFS:lol:
