I just purchased mine (2) from Sunrise Ford in Fontana CA.
Cheaper than the usual suspects and free shipping.
They are my OE dealer of choice.
I also have axles with rings on them already, OE 25k original miles from my 08. I just recently upgraded the entire rear and will be selling all the OE I replaced.
Went with a trutrac 3.73 with strange axles and Frpp one piece DS as part of my supporting mods for my Centri build.
None of the OE had issues, just upgrading.
Get new ones. Before pressing them on very gently use some emory cloth on the inside to make sure it is perfect for install.Same I'm upgrading the axles and just want to go ahead and avoid prying the old ones off.
