Hey, friends. It's Len here at 1A Auto. Today, we're working on a 2007 Toyota FJ Cruiser and we're going to be replacing the transfer case fluid. It's going to be a very easy job and I want to be the guy that shows you how to do it. If you need any parts, you can always check us out at Thanks.

Okay, friends, so here we are, we've got our transfer case fill plug and the drain plug. We're going to remove the fill plug first. In case there's an issue, we won't have it completely drained before we're stuck with no fluid in our transfer case. Make sure we have our collection bucket, eye protection, hand protection, just in case any fluid comes out. Looks good. Here's our plug, 24 millimeter. We'll set this aside.

Now we're clear to remove the drain. Fluid's going to come out, so make sure you have your receptacle there. Same socket--24 millimeter. Let's try to get off some of the crud. The fluid's going to come out. There we are. We'll let that finish draining out and then we'll move along. I'm just going to clean this off along in the threaded area, if I can, along where the gasket's going to ride or seal, whatever you want to call it. Just go along and make sure it's nice and clean and shiny. We don't have any big chunks of anything in there, debris. That looks good. Set that over it. This is going to be ready to go back in. Before that, we're going to come up here with our rag, and we'll just clean off around the drain hole. We'll put this in, and I'm going to bottom it out, and we'll torque it down after we fill it and put in our fill plug.

Okay, it bottomed out. That's good enough for now. We're going torque this at the same time as that. All right, so now we're going to go ahead and fill this up, 75-90. Sometimes these bottles make some funny noises when you're filling, just so you know. Gets me every time. I guess I'm just one of those guys. Okay. That's quart number one.

Let's grab some more. Quart number going in. It should take a little less than a full quart here. All right, there we are. So that's just over one quart. We'll let that come down to a slow trickle, and then we'll go ahead and plug it up. We've got our fill plug, nice and clean. Go ahead and put this in here. There we are. Just wipe this down so it stops dripping.

Now we're going to torque both of these 27 foot-pounds. There we are. Okay. I'm going to use my 24 millimeter socket. That's the fill. Here's the drain. And I do it one more time, just real quick. It's definitely tight. Definitely tight. We'll clean this down the rest of the way and we should be all done.
