Where do I find the info on my 98 F-150 that tells me what rear end came out in my truck ?

 

Get the axle code off the sticker on the driver's side door jamb. Post the code here or search what the codes relate to in ratio. You can also get the exact ratio off a metal plate attached to one of the rear end cover bolts. It's the first few digits on the left of the second row of information.
