Just finished up this evening. Getting the seal out was pretty easy. Putting it back in wasn’t that hard especially with the right tools. I took my time and made sure it went in evenly. I used a 2” pvc coupler plus part of the seal driver tool I rented. I couldn’t use the driver handle since I didn’t have enough room to use a hammer too.
Hopefully it’s fixed. It’s a shame that I had to replace the diff oil since I just changed it 10k miles ago when I did the CVs.
