stuck diff plug

[bluedog]

I am having trouble getting the diff fill plug out. It simply won't budge at all. I have only had the car 12 months and am keen to check on the oil level. Is there any risk of breaking anything if I use more force?

No, you.re not likely to break anything. Just use the longest lever or extention on your removal tool, It will give. Just make sure that your driver has a good snug fit in the fill plug. Good luck.

As Runnerbun said the main thing is a good fit with tool to the plug
you can also heat round the plug a little just go easy with the heating

Times 3 on the good tight fit.

If some of the threads stick out, just put a serious ding on the side with a center punch, then angle the punch & rap it HARD, to break it loose.

A hand impact driver with a tight fitting adaptor? A of course use a Big Hammer times 2 like what Bill said

Yes, A hand impact driver (not a pneumatic impact), a tool that is often overlooked but usually works.

B.H,
My most commonly used hammer is a 48 Oz Ball Pein, with a 2/3 length handle, for BETTER control

If the hole is rounded out, you can take an old Vw wheel stud, grind it to a tight fit then use a socket and the hand impact wrench.

Don't forget to apply some penetrating oil the day before.

Two things..

One, make sure you have dug out all the dirt and grime from the 3/8" square hole in the plug. All the way to the bottom.

Then, using a 3/8" drive socket wrench with a long extension, the plug will probably come out.

Did just this on mine a couple days ago.

Re: stuck diff plug/ get it clean

yes to thoroughly cleaning out the plug...use your dental picks or whatever, but get it clean, side to side and top to bottom.
I have used an impact wrench basically set to off (very, very low) and just let it chatter away until it spins out.
The acetone/ ATF mix might help loosen things for you also.

3/8" square drive will often work, but the correct size should be 7/16", so try to find a piece of 7/16" square shaft, or a 7/16" square head bolt, then weld a T handle to the bolt head.

Couldn't you double nut two 7/16 nuts on a bolt and use that?

Yes, it's worth a try. I used a 7/16" square head bolt and clamped onto it with a Vice Grip when I didn't have my correct tool with me.
