ok so i got a 3/4 ton dana 44 but i thought it should have a 12 bolt cover ????? so why does mine have 10 bolt cover and 8 lugs ?????? please tell me it is a 3/4 ton !!!!!!! the guy was running 38's all day long on this under a k5 and never broke anything so i am hoping this will work for me . please help . :confused:

well if its 8 lug then its 3/4 ton the only difference between 1/2 and 3/4 is in the outters or if you end up with a hd 44 with bigger tubes are you sure is a 44 and not a gm 10 bolt and i always thaught that 44s had a 10 bolt cover?


on a side note my truck had the 3/4 ton front and with 39.5's broke em constantly

um.... 10 bolts are all you get with a 44, unless someone drilled some extra holes in it.

Well, there is the hole for the fill plug:p

and the vent tube.

GM used both the D44 and Corporate GM 10 Bolt as 3/4 ton, really just a 1/2 ton axle w/ 8lug outers. IIRC they stopped using D44 around '77-79, and started using the 10 bolt. While both have 10 bolts on the diff cover, the 10 bolt is cover is round and symetrical, while the D44 is more "squared off".

D44:

GM 10 bolt:

1 of my friends said a true dana 44 has 12 bolts but i guess he is the f**king moron . thanks for the info though !!!!!

Some people mistakenly refer to the rear ends in older Chev's with 44 fronts
as 44's - when they are 12 bolts.

yea that of been .
