I have a 2003 F150 XLT 4x4 with the 5.4. I'm needing to replace the passenger rear axle. Can anyone tell me what year if any will be compatible with it? Any information would be greatly appreciative.

 

I bought mine from rockauto. That is when I found out that some 9.75" rears had different diameter axles and bearings. There should be a code on the tag on the rear diff cover bolt that will identify which axle yours has. I of course ordered the wrong one the first time.
