Exclamation Any Suggestions? (Differential Filler Plug)

Tried everything it wont come off.. WD40 doesnt work, full force don't work.. I do not have a impact gun, the insert of the 1/2" is starting to get damaged, 1/2" ratchet drive has taken a beating , and losing patience.. Any suggestions would help.. Thanks.....

well, use some penetrating oil. Like PB blaster, or liquid wrench.

if that doesn't get it try a heat cycle with the 'ol propane torch.

if you're using the liquid stuff to loosen it make sure you close the bottom part, don't want that stuff going inside your diff

Rent an impact gun. I'm guessing you're doing it at home? Meaning no lift, meaning you can't use a 2 foot breaker bar to its full potential.

I used a short breaker bar with a floor jack to apply huge force (the weight of the car). The car was on the ground.

if you are starting to strip the plug itself, I wouldn't use an impact wrench. The force from it will totally strip the plug.

Get a 1/2" breaker with a pipe AND get another person. One person has to be under the car to make sure the 1/2" breaker is in there nice and square.

Good luck, you should've loosened the fill before the drain plug.

It wouldve really been easier to take it to the shop really, but i was short on $, ill buy a breaker bar , and i'll definately need to start working out lol , ill try to get like a wooden block underneath the diff on top of the jack to see what i can do.. unfortunately the inside thread is starting to mess up, i'll probably need to buy the fill plug down the street ( capitol subaru ) good thing i have a commuter beater ..
