Forgot to update this earlier. The oil seal I ordered was the correct one and other than getting the drive shaft off the spindle at the front the job was pretty easy. Adding gear oil in the lower fill hole was pretty easy but the upper one (through speed sensor hole) was a pain - next time I'll remove the box. It's been tested hard since I did the job and I have no issues. I am going to make myself some covers to go over a couple of the bigger openings in the skid plate though to avoid this happening again.
Great to hear you got it done. Thanks for the information as well. I see you added the part number in a previous post in case anyone else has this issue in the future. Enjoy. 😎👍
