I need to order a part (ubolts) & I have to know what model differential I have in my truck. How do I know if I have a DANA 60, 70, or 80.....I have an 02' 4X4....Is there a good way I can find out for sure what model mine is? I noticed it mentioned sales code DRD or DRE....What exactly is this? Thanks for any help or suggestions....

 

You have a Dana 70u used in all autos and dana 80s were used in all sticks and 3500s

 

The fronts is those trucks are all dana 60's. Auto trucks got a dana 70 rear and manual trans trucks got a modified dana 80 rear.
Are you asking about the front or rear diff?

 

Thanks guys. I appreciate the help.

I was asking about the rear diff.....I just have to order a new set of ubolts for the rear....couldn't get the old ones off & wound up having to take one off with the grinder.....

Thanks again.
