Rear end wrench

-
Most I've seen take either a female square for a 1/2 drive ratchet or breaker bar (with no socket) or a male square for an open end wrench or crescent wrench.
 
Just pop the drive of a 1/2 inch ratchet wrench into the hex-looking thing and screw it out.

I see someone disagrees with this statement. Not sure why. If we're talking about the fill plug on the differential cover of a 7 1/4 rear end, that may look to modern eyes like it takes a Torx fitting, but it's not. To my knowledge Torx wrenches didn't even exist in 65. At any rate, the half inch drive of a ratchet wrench is what I have used many times, and I found a You Tube video that shows how a half inch drive (in the video, of a breaker bar) fits the plug perfectly.



An 8 3/4 rear has a fill plug on the passenger side of the chunk. That plug takes a 5/8 open end wrench.

Yes I tried it and it did work. Thanks
 
I tried a 1/2" socket extension on that plug in my 7.25" rear of either my 1964 or 1965 (forget, a few years ago), but couldn't budge that plug. I even tried heating it with a propane torch. I didn't try an impact wrench, but recall it was already starting to round off the squares, so probably wouldn't help. I just wanted to check the oil level. Maybe I need to try welding torch heat. If I drill it out, not sure where I'd get another plug.

BTW, the head bolts on my 1985 M-B diesel have a similar looking 8-point female socket head, termed "double-square". I had to buy a special socket which looks kind of like an allen wrench for them, but metric so doesn't fit the Mopar plug. Aerospace uses many 12-pt bolts (termed "double-hex" I recall), usually in male form, but a standard 12-pt socket fits.

it would be nice if to disagree, you had to give a reason
I have often wondered about that too when disagreeing made no sense at all. Maybe it is because the agree and disagree buttons are side by side. Then being forced to justify the disagree would make even more sense.
 
I've hit it by mistake a number of times just scrolling. A couple of times folks PM'd me and asked about it. I just went back and removed it.
probably happens more with people posting from their phones. small screens and too many of us with old eyes :lol:

Maybe something as simple as a pop up script that said, "Are you sure you want to disagree?"
 
like this?

If the plug is stripped and has a flange, i hit the edge with my air chisel. That will move it. Then install a new plug. Or weld 1/2” nut to it...
