Has anyone noticed the HUGE fill port on the front differential? What's up with that? I swear you could drop a golf ball in there. It's got this giant machined steel hex head fill plug, then a tiny little hex head drain bolt. The drain is so small I dont see how you could even get a metal filing out of it. The transfer case has two identical steel plugs with an allen wrench recess in them, then the rear diff on mine has just a fill plug that accepts a 3/8” wratchet handle. Nothin' like consistancy all the way around.:crazy: I went through and checked all the fluid levels and condition on my 2005 @ 21Kmi, all three lubes seemed a little dark, but the insides looked clean on all three thru the fill holes w/ a flashlight. I buttered up the plugs with never-seize and buttoned everything back up for now. How are you guys filling these back up? Squeeze bottle with a hose, or suction gun? They look like a horrible mess to fill.:worried:

The hardest one to fill is the transfer case. I used a squeeze bottle and ended up having to purchase 3 liters of fluid instead of 2. I couldn't tilt the squeeze bottle up high enough to get more than half of the fluid out so I just kept refilling and then ended up throwing away almost the entire 3rd liter that I had purchased. :(

I did the same thing that the previous poster did for my rear diff. *shrugs* As long as I got enough in there.

I used a suction gun and lost little fluid in the transfer. It's a PIA to keep having to refill and get back under the vehicle, but at least it worked. Would have been nice to have a drain on the rear differential instead of having to pull the cover.

How about one of those oil cans with the trigger

You might be on to something there! :thumbsup:You can get those cheap enough at wally or harbor freight that you can keep it just for stanky gear oil service.

Most of the auto stores sell a pump with a plastic hose that will screw on to to the bottle. I bought one about three years ago and it works great.
