Need Advice Re: Leak on my 2007 Sport (With Pics)

// Apology - Please read this only then skip to post 4 below (has pics). Thank you, [MENTION=130999]Inv4drZm[/MENTION], for helping me realize that my original post was two things I never like to be: lazy and inconsiderate. The first move anyone should make before asking here is quite obvious - crawl under the truck and see what you can see. When I did that this morning, I was immediately able to locate the leak. I would still appreciate any advice as noted in my post below and I regret wasting the time of those who read this thread before I did my homework. //


Noticed a spot on the concrete where my '07 4WD Sport had been parked for only about 45 minutes. It was maybe the diameter of a CD and at first I thought it was water - very clear and didn't leave any color on a white paper towel - but there was a faint oily smell. This was after driving home from Lowes, about 30 minutes away, pretty loaded down - 9 4x8 sheets of 1/4 inch plyboard, a bunch of molding and lumber, a couple of saws and some groceries. Load was several hundred pounds more than normal for sure.

I haven't had a chance to take pics or do an extensive inspection yet but all of the under-the-hood fluids are at normal levels and it looks as if there's a coating in the vicinity of the front transfer case.

Read up on various leaks here on the forum and am hoping to get answers to a few questions:

1) In threads where posters cited the year of their rigs (very helpful when doing research), just about all of the 4th Gen transfer case leak issues appeared to be with 2003-2005 models. Has anyone had it with a 2006+?

2) The truck was driving normally up until I saw the leak. Assuming it is the front transfer case or actuator seal, would it be unsafe or potentially cause more damage to drive the truck in 2WD until it's repaired?

3) Does the fluid description match what's in the XREAS? Though I think it's a long shot, that would be much preferred over a t-case leak. ;-)

3) Any advice on narrowing down the source as much as possible? I like being as informed as possible when discussing with my mechanic.

Thanks for any help.

Its not your transfer case, that oil would be black if it hasn't been changed very recently or at least leave something behind on a paper towel.

Did it feel like oil or was it runny like water?

Pics of the pool or of the oil on a white paper towel along with where it looks like it is running down the vehicle will help the experts on this forum a ton.

Thanks. I changed the front t-case oil 1 year and 14K miles ago. What leaked was pretty thin - more watery than heavy like motor oil.

I'll follow your suggestions asap. It's freezing outside right now and I'm also in the middle of a major home reno project.

Also, I edited my original post for future readers to add that this occurred after driving home from Lowes pretty loaded down - 9 sheets of 1/4 inch plyboard and a bunch of molding and lumber. Several hundred pounds more than normal for sure.
 
Got a chance to get under the truck this morning and this is what's leaking. Location is where the passenger side front axle is connected. I'm having trouble identifying the part from the exploded diagrams but possibly the inner joint assembly?

Any help/advice much appreciated on 1) what part this is, 2) complexity of the repair, and 3) is the truck okay to drive 30 minutes to my mechanic's shop if necessary. Thanks.

Kind of a side view

That my friend is a leaky passenger side differential seal. My driver's side did the same thing a couple weeks ago and I replaced it myself. Your mechanic needs to pull out that side's CV and that will gain him access to the bad seal he will just pull out of the differential housing and replace. $20 in parts and a couple hundred in labor maybe. Unless you want to attempt it on your own (Its the same exact process for installing a new CV) You should be able to drive it to your mechanic.

Pictures and a how-to for CV changes:

Thanks, [MENTION=130999]Inv4drZm[/MENTION], much appreciated. Is this part the one you replaced on your driver's side? (It's #6 in the illustration on the linked page.)
 
[MENTION=130999]Inv4drZm[/MENTION], thanks again for your help. Got the seal replaced yesterday.

The local Toyota dealer is much closer to my house but wanted over $100 more for the job. My mechanic did it for $220.
