Would be interesting if this was initially caused by the synthetic diff oil I used or pressure build up in the diff before I did the extended vent mod..
Because my bearings feel very tight with zero play, and nothing is leaking in the drums I am putting off this bearing repair until I find oil in the drums. Could be next week.. could be months or years. Following the old saying, "don't fix it if it isn't broken. And if it isn't broken completely, well let's just fix what we need." (I may or may not of added that last part)
For now I put OEM Toyota shoes on, got my drums resurfaced and refilled diff with non-synthetic oil. My brakes are so smooth and have worked flawlessly in the cold so far. I'll bring you an update in the future to see how I'm doing. Thank you EVERYONE and I hope the info generated here helps other people make their decisions!

Well, you better keep a close eye on it now that you've decided to roll the dice and not do anything about the leaking axle seals. The problem isn't going to get better, it's going to get worse. The only problem with your logic is the problem might get worse in the middle of a long road trip. If you don't plan on driving far distances with your rig, I'd say your choice is ok. But, if you're planning any big trips with this rig, you may very well regret not addressing the issue.
As more gear oil gets past the seal, it will be making it's way into the bearings and washing out the grease and then eventually make it's way into the brakes. As long as the gear oil level doesn't drop down too far, the bearing will be ok because it's now partially be lubricated by the gear oil. If enough grease has washed out and the gear oil drops down far enough to where the bearings aren't receiving ample lubrication, and you go on a long enough drive, your bearings could overheat and implode on you. How do i know this? A guy who came to one of our YouTube Subscriber parties barely made it to my place in San Jose from Auburn. He ended up destroying his passenger side axle. Lucky for him, the place he broke down at had a guy, Me, who knew how to fix it. He was lucky he was able to find an axle at a local PicknPull that day or he would have been stuck.
Good luck!
