I bought my 98 f150 a short while ago, and recently (due to mechanical problems) realized that the original differential isn't in the truck. I know that i need an 8.8 3.55 diff for the truck, but i don't have the tag number that every parts shop in town seems to need. as there is no tag on the diff, how would i go about finding this?

 

Go to a junkyard and buy a whole rear end.

 

so i went to the junk yard. now i have to remove the break lines and such from my rear end. it hasn't been a problem until this:


sorry about the size. also note, the wetness is wd 40 and some leaked oil

how do i take this off without cracking break lines?

thanks for the help

 

Those lines look like they should be replaced anyway.

 

x2!
