no "35". what's my rear end?

 

if its for that F250 in your sig, its probably the Ford 10.25. Try to get some info off of the tag on the diff itself

 

This is the page you needed:

https://www.ford-trucks.com/article/...de_Chart_.html

35 is 4.10 gears, 6250lb rating (usually limited to 6084 by tire rating)

It's the Ford/Sterling 10.25" full-float axle.

cool, thanks

just curious, why does it say "Year 1991"

 

Whoever compiled the list probably had that year of truck (and owner's manual). But the codes didn't change from year to year that I'm aware of.

My '93 has axle code 35, and it's the same thing, and my '90 was axle code 19, and it was the same as that list.

gotcha, thanks. 4.10...wow. who needs a house pulled down
