Rear end id? please help.

After looking at pics again, can make out 44, but that’s not 44 I’ve ever seen...

the really strange thing is that i have 2 trucks with this unknown rear axle in it.
the 1999 tahoe 2 door, and a 1997 c1500 shortbed

Did you buy from the same PO? Maybe ask him?

Hello

I have a 1999 Chevrolet Tahoe 2 dr, 2wd, vortec 350. i have made some improvements to the engine and now i want to add a locker to the rear end, BUT i am lost! i really cant identify the rear end in this thing.
does anybody know which rear end this is? the cover says Spicer on it.

Pic attached.

Thanks.

Randy's worldwide might be a good resource for this, just trying to match up the diff cover on there, they usually have pics. Although you'd kinda have to guess at the OEM make/model.

Numbers show 38-11 ring/pinion ratio, so it’s a 3.45 if that helps narrow it down.

except mine says Spicer.

maybe it is because my tahoe is made for the market over here? just seems strange that our other trucks has regular 10, 12, 14 bolts

Can anyone identify this rear diff for me on my 95 gmc suburban k2500 7.4L? Im think its a GM 14bolt 10.5" full floating open differential?

Sorta looks like a Dana 44 but different bottom.

I see a "DANA" on there

Spicer = Dana. More commonly stated as Dana-Spicer.

I'm kinda guessing Dana 44, but that's without research. The Dana 70 was used on some GMT400s, and I think the C3500HD got a bigger one--Dana 80 or some-such.

What doesn't make sense is that the Dana 44 is roughly equivalent to the GM/AAM 8.5" axle in terms of strength, except it doesn't have an exploding differential case like the 8.5 is known for. GM used to sell a Dana 44 axle assembly over the parts counter, to fit the third-generation Camaros as an upgrade over the pathetic 7.5" axle.

A Dana 60 is approximately equivalent to a GM/AAM 9.5" axle; which is perfectly adequate for full size trucks suitable for 6-lug wheels. Which makes the Dana 60 quite the tough rear axle on those Hemi Mopar 'Cudas and Chargers.

Your particular axles were maybe installed as part of an "export vehicle" program, maybe they figured the Dana axle would be easier to get parts for in Denmark.

Just a few days ago, I was researching the origin of "Salisbury" rear axles.

Turns out that Salisbury was a New York company making product including axles in the early 1900s. They were bought out by Dana in 1919--just after WWI, and a few years after Charles Dana bought the Spicer Manufacturing Company, a maker of the now-common "U-joint". Salisbury became the Spicer Axle Division of Dana Corporation.

Eventually, Dana-Spicer set up a company in England to produce licensed versions of the axles. The Dana 44 became the Salisbury 44, the Dana 60 became the Salisbury 60 when manufactured in England. The axles were not identical to US production, but recognizably similar.

With production of the '44 in England, vehicles shipped to Europe maybe got the Dana axle instead of the AAM axle.
