RR Axle Service Questions

Getting the seep shit around 3rd member/axle housing. Yes, I have torqued down all the bolts but still persists. No, not 2016/2017 so not in recall. So, will be gathering parts for rr axle service. Will be doing rr brake shoes since never done and at 155k miles. Have to remove to pull axles anyway. I would like to also replace axle seals on both sides along with 3rd member gasket & brake shoes. Can't the pinion seal can be done from front of 3rd member by just removing driveshaft and yoke on 3rd member? It is dry now but probably need to do it too since doing the rest. This is just open diff? that comes on 08 RC SR5 prerunner. Not elocker and pretty sure not limited slip. Any other seals or parts I should replace while doing this?
