I changed both my front axles with remans last week. I did passenger first, thinking it was the only one I needed and noticed the driver was bad when I was under there. After the first time I did the passenger, the diff seal was leaking. I definitely recommend replacing that but be careful doing so.

I'd also recommend buying OEM knuckle seals along with both axle/diff seals. Be careful putting them in. I changed out that passenger one 3 times due to putting it in too far and one time slightly crooked. The lip of the seal will protrude from the diff housing if done correctly. I also stopped using the seal driver for diff seals, did it mostly by hand, and used a punch to even it out and finally get them set. No more leaks after a week but it annoyed TF out of me to pull that passenger axle basically 4 times in a week. I did use the seal driver for knuckle seals.

This thread helped me to get it right - 3rd time replacing leaky front axle seal with OEM. Why does it keep leaking ? | IH8MUD Forum

The Reman axles are very low in inventory. I called many places and dealers told me I could only order one if I came in. I went in person to my local dealership parts people that are familiar with me and they were able to order two from New York. IIRC, they said 5 total remained.
