It's identified as a Corporate HO52 or non-Dana is how GM books list parts.It is an Eaton center section.There's a guy selling shafts in the parts board right now.How'd you break that beast?

Looks like the 6 lug semi float version...

brew8 · 10-31-2010, 05:06 PM

ea, It's 6 lug simi floating, must be very rare or from the 50's, too much skinny pedal is what did it in, bummer, I have a 10 bolt rear, I put new bearings in I guess I couid change the spring perches and use it but I have no Idea what to use for emergency brake cable I think mine on a 62 truck woulkd be too short, Thanks, Larry

I have never came across a 6 lug version before what trucks did they come in?

b454rat · 10-31-2010, 05:19 PM

There *was* one in my 62 burb 4x4. I'm guessing early 60s...

**special-K** · 10-31-2010, 05:23 PM

I went by the first picture.I thought that was a different axle on the floor jack.Now I see the flange on the axle shaft has 6 studs and it is a semi-floater to boot.Good eye Rat.That will be a hard one to find.It would be nice to replace with a 14-bolt 6-lug semi-floater.But,you already have the 10-bolt.
what truck is that under?Is it a Napco?

brew8 · 10-31-2010, 05:46 PM

It's a 62 SWB fleet side K10

**special-K** · 10-31-2010, 08:50 PM

That would be the same axle as the 50s.I asked Napco because the rear would be the corporate 2wd.

That's the normal 1/2 ton rear used 55-62. Some people call it an Eaton, but it was actually made by GM. I believe the GM designation is either H033 or H035.

My 60 C-10 has basically the same rear, except with brackets for the trailing arm supension. The most common ratio is 3.90, but they were also made with 4.11 and 3.38, the last being quite scarce.

I'm not trying to hijack this thread....

I just don't see the sense in 10 different threads asking the same question.

So,
Could somebody identify this front axle?
it's on a 1979 1/2-Ton Chevy Suburban.

Thanks

brew8 · 12-20-2010, 11:21 PM

GM 10 bolt

LostMy65 · 12-21-2010, 08:20 PM

^Thanks.

If it is safe to assume the front gear ratio is the same as the back, then is a 3:40 a good ratio?

Depends on what you're doing with the truck.... for a fairly stock street-driven truck, 3.40 is a good all-around compromise. Low enough to give you decent acceleration, low-end grunt, and towing power -- and high enough to be driven at highway speeds. Not too bad for fuel mileage either, but that's kind of a moot point on most of these trucks anyway.
