I got the numbers off the long tube on my 44 and am having no luck finding any info on the year vehicle it may have come from.If anyone can help me with a website or tell me where it came from it would be greatly apprieciated

the bill of material number is 610036-3

the date stamping (or at least what I believe to be the date) 4 14 8 5CE

610036-3 is a front 44 from a '78 half ton truck or Blazer.

It came open with 3.73 gears.

Does it have a tag on one of the diff cover bolts? If you want to be 100% sure then pull the cover off and read the numbers on the ring gear 41:11 = 3.73 (just divide the numbers to get your ratio. Every diff could use some fresh oil anyway...

thats exactly what I needed to know thanks! I didn't see a tag on the thing anywhere but someone has been in it before so I need to pull the covers to make sure they are the same.So should I assume the 12 bolt out back probably came from the same 78 truck/blazer?

msgross · 10-05-2008, 12:32 PM

i'm not sure when the 12bolt rear merged over to the 10bolt. I have heard that the dana44 went to corp10 bolt front in 77 or so though.

very similar axles with a lot of matching parts, not all though...

84lwb · 10-05-2008, 01:04 PM

well i hope that it came from the same truck and not this one cause unless a PO changed the gears then the original gears are 3.42 with a gov loc and i've heard they were'nt that great.(gov loc that is)

msgross · 10-05-2008, 01:08 PM

send pics, remove cover and send more pics...

those #'s on the ring gear are the ticket

84lwb · 10-05-2008, 03:00 PM

I really don't want to crack em' open just yet.I've still got quite a bit of work to do to button up the motor install,plus new ujoints in both driveshafts( my wife is gonna kill me by the end of all this

)but I'm trying to get all this done by the end of the month so I definetly have alot to do.I'll get this all straight soon enough though!

Blazer1970 · 10-06-2008, 06:26 AM

The 12 bolt is probably from the same truck. The switch from the 12 bolt to the 10 bolt in the rear was not until 1981. GM did start using front 10 bolts in '77, but a lot of '78s still got Dana 44s.

84lwb · 10-06-2008, 08:00 PM

with my truck being an 84 i didn't think it came with those axles even with it being a diesel originally.i definatly appriciate all the help.

earl87gta · 10-07-2008, 08:37 AM

84lwb · 10-07-2008, 08:10 PM
