Help I need to identify the rear differential

[jim5233]

I recently got bad vibration in my rear end. I thought it was a u-joint but turns out it is the rear differential. Anyone know what size rear differential comes in a 2003 explorer Eddie bourer edition with the 4.6ltr? Has anyone ever had this issue before?

All 2002-2010 explorers came with an 8.8 31 spline IRS diff. Gearing and limited slip options varied. Look at the tag on the edge of your driver side door for the axle code which you can put into google and it will tell you your gearing and if its a limited slip or open.
