Seriously, how in the heck did you do that ..... ??

I'd suggest you just go to a dealer and get a new drain plug ....... I wouldn't just pick up any old bolt from a hardware store.

Then, after you secure a new plug, if it will screw into the differential without leaking, I suggest you build a skid plate for the differential or, better yet ..... STOP OFF ROADING!

Lol this is actually the second time it came off I found it last time.
I wish it was from off-roading that would be fun. My car was really low and the diff was 1/2 an inch from the ground so after continuous scraping it came loose.
The dealership wanted $15 bucks for an Oem bolt and washer.
I picked up a drain bolt and gasket from car quest for $4, no leaks so far after a 1 hour drive.


For future reference the drain bolt size is m18x1.5x12.

Well, in that case, forget the skid plate ....... you would just high center on a drunk bump ..... :eyebulge:

Bubba suggests you weld one of these on the bottom of your differential..... :D

Well, now, 2" is much better. Assuming you gave up off roading, the only thing you have to watch out for is the raised gas tank fill covers at some service stations ...... :eyebulge:

Yep, hit one of those and make some sparks ...... and KABOOOM ...... your car's new ride height is about 6 feet off the ground, upside down.

I hit one of those in an in-lowered miata, up in Canada, put a big gouge in my under panel. Another Canadian station that I stopped at on that trip, the click off on the filler nozzle didn't click off as I was inside the station taking a leak.

There was about a 40 liter gas puddle surrounding my car. The dude tried to charge me for 80 liters ........ I paid him for 35 liters and pushed my car out of the puddle and drive off.



Lesson learned: Don't leave your car when you are refueling ........:)

@Cole @Tcoat ........ is that a Canadian trick to sell more gas ...... ??
