2010 long bed tundra bearing assembly replacement question. Please help!!!

I have a V8 5.7l long bed 2010 Tundra.

I need to replace the left rear bearing. This Tundra has a bearing assembly with two bearings inside rather than a single bearing.
With this Tundra, one can replace the bearing only by replacing the bearing (housing) assembly as a kit. So I have to buy the whole assembly. Darn! I just can't push the bearings out and press the new one in on the spindle. I need to buy a whole new assembly for lot of $.

So I am planning to do it on my own.

Question: Is the bearing assembly easy to replace? I have replaced bearings before. Do I just slide the new bearing assembly in and bolt it in? ....or is it more complicated? How do I do it? I have looked on youtube and forums but couldn't find anything. Replacing regular Tundra single rear bearings is well documented however there is not too much info on replacing bearing assemblies with two bearings like mine.

Please point me into the right direction!

Thanks so much!
