Great, thanks. One suggestion I have is to use a paint marker on each of the 4 driveshaft nuts/bolts when you put it back together. On my rear end I used the guttentite method and they started working loose. A good idea to monitor these things for a while after putting drivetrains or suspension back together. Maybe if I torqued them properly they wouldn't have come loose but they were pretty tight.

I think you need to start pumping iron Bro. One day you could even be as manly as Timmy the Toolman. I was going to enter one of those strong man competitions but decided to start a YouTube channel instead.

Thanks again Tim.
An alternative for cheap buggers like me. A free crowsfoot built just for this task. Excuse the welds, it was my first time welding.
The extra length of the crowsfoot does change the torque spec slightly. Formulas for this calculation can be found online, look up "torque adapter". It worked out to 2 or 3 lbs/ft for my adapter. Not too significant.

I have to ask Tim if you have ever tried freezing a new seal for 24 hours before installing? Just enough shrinkage can be the quick ticket.

I haven't tried it yet but I've heard of it. I pretty much think I made it harder than it had to be getting the seal driven in. With an application like this, I worry about getting it right because you can drive it in further than you need to get it in and then you're pulling the seal, driving to your local dealer and hope they have the seal in stock. Analyzing how the companion flange inserts into the transfer case though, I know you could drive the seal in further than flush and be fine. I just want to show how to accurately insert the seal based off the instructions in the FSM. One of the main things Sean and I want to ensure is we pass on good info to the viewing public. This is why you sometimes see me doing corrections in videos because we realized after the fact we screwed up.

It's the same type of seal and quite possibly the exact one as the rear. You would need to confirm this by looking it up on an online parts seller website or by visiting your local Toyota dealer parts department. Remove the companion flange and replace the seal like we show in the video.

Output shaft seal?
Did they revise the part? Looks a bit different to me?

This video was super helpful for my repair attempt and his use of a seal installation tool inspired me to 3D print my own set of install tools.
