Front diff fill bolt

[swathdiver]

There is another spot to fill at ?

Both plugs are facing the driver's side. The lower one is smaller and in the center. The fill is to your upper left and quite large. There are drawings of them in your owner's manual. For a 2009, it's on page 5-52.

I believe he is asking about another place to fill it because he is having difficulties with the FILL plug and you suggested siphoning out of it. Won’t work if he can’t remove it.

I just changed my front fluids last week and had a heck of a time with the fill plug as well, PB blaster and patience ultimately got it out.

You're right! My reading comprehension skills are not what they once were!

allways start with the fill port, if the drain comes out but not the fill you cant service it. since it is only a drain plug it limits the amount of cleaning/flushing you can do anyway. as previously stated, siphon out of the fill plug and forget about it! dont fix it til it breaks as i have been guilty of to many times to count. harbor freight siphon pump $7. oops, if i also misread your post, is it already drained? if so still use a siphon pump and drill out a old wine cork to allow the tube to pass through, install in the drain hole and put the prescribed amount of fluid in. then quickly! pull the cork and install the plug. i know it is a mess but you wont lose more than an ounce or two of fluid.

It's the fill plug that is the issue not the drain plug

Great tip!

Anyone else have an issue getting the fill plug out of the front diff.

I am making a long trip the up coming weekend towing a trailer and I wanted to change out the fluid. The fill bolt was so tight I snapped a breaker bar and started twisting the bolt.

Any tips from people in the same situation ?

Had the same problem with mine. Drove around to get front diff nice and hot, then melted about ten ice cubes on the fill plug, and with a little persistence the plug busted loose. Make sure you use a six point socket or you’ll stip it

I am going to hit it with some PB plaster in the morning, and then right after my drive home tomorrow it should be hot enough to try and pound a socket on and remove. I really want to get this fluid out before I make a 1000 mile trek with a trailer.

Well this was an epic fail the head of the filler just crumbles even with a 17mm socket hammered on. I put kroil on it this morning and drive it to work and then again when I got home. Tapped the case with a soft mallet and then tried using the breaker bar with no luck. Next I tried to use my 3/8 20v dewalt impact and still no go.
