ok my buddy has a 83 suburban. with the 6.5 diesel in it.
new years he exploded the spider gears in the front diff. and we are having a problem figuring out what front axel he has. one guy says a dana 44 . next guy say somthing else.

stupid thing has sooo much grease i dont know where to look for numbers etc.
anything would help.. thanks

 

i doubt i has a dana 44

if the cover is round it's just a chavy 10 bolt
if it has 6 sides it's probably a dana 60. those usually came one the 1 tons

unless it was swapped it has a 6.2L

 

as long as everything is stock and it is a 1/2 ton it is a corporate 10 bolt 6 lug. if it is a 3/4 ton it is a corporate 10 bolt 8 lug. if it is a 1 ton it is a dana 60 8 lug... take a look in the glove box there will be a sticker in there with the alxe ratio and type of rears that are under the truck....GM stopped useing dana 44s in 1980..

 

your probably right... i hate the thing. but we can load 8 people in it and drive to a cave or mine to explore. ill look tomarrow


many thanks scarecrow, bow2no1!

 

if the cover has a plug to put gear oil in then it's a dana if not it's a gm coporate

 

so its a gm 10 bolt. got that figured out after removing 3/4" of structural grease. now i need to find out where to either get parts to fix it , or a place to get it fixed in socal. what would the gear ratios be?

 

gear ratio........the should be a tag attached to one of the cover mounting bolts..................if no check for a tag on the rear diff as it will have the same ratio

Spider gears dont matter what ratio ya have............unless ofcourse ya trashed the ring and pinnion
