WTB eaton rear-end fill plug - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**JIMs70GMC** · 06-01-2004, 07:27 AM

That's what I need. Mine's almost rounded off. It still seals but is a pain to remove/install. I'd like one that's nice and square. Thanks,

JimKshortstep4x4 · 06-01-2004, 10:35 AM

Isn't that a 1/2" NPT pipe plug with a square head? Hardware store should have one.

Jim

**JIMs70GMC** · 06-01-2004, 10:41 AM

Nope it's a lot bigger and has a flange that seats on the cover.

Dean · 06-01-2004, 01:09 PM

Well the good thing is you know a previous owner filled the fluid at least once....bad news is I guess they only had one tool....vise grips....lol

I probably should have picked up a few of those in junkyards over the years.

**JIMs70GMC** · 06-01-2004, 01:32 PM

Dean, I went through and checked all the fluids this weekend, just to see how it was doing and had to use the vice grips to get that sucker off. I figure somebody should have one sitting around.

**67sss** · 06-01-2004, 02:54 PM

would it be the one on this cover?

Dean · 06-01-2004, 03:00 PM

That looks like it to me.

da-burb · 06-01-2004, 08:51 PM

I welded a nut to the last one that was rounded off. Wasn't pretty, but it was functional....

**JIMs70GMC** · 06-01-2004, 08:54 PM

67sss, that's it. da burb, the one I have also has a chip in it down to the and including a chunk of the flange.

**67sss** · 06-02-2004, 12:09 AM

JIMs70GMC- pm you

**JIMs70GMC** · 06-02-2004, 09:58 AM

PM'd you back.

2wdBlazer · 06-02-2004, 12:10 PM

Time for a chrome cover. They come with plugs too.

junkyardjohn · 06-02-2004, 12:16 PM

YEP-- I JUST HAD MINE OFF YESTERDAY IN MY TOWTRUCK TO CHECK THE FLUID LEVEL. I WELDED A 3/4" NUT TO MY PLUG. NOW IT TAKES A 1 1/8" SOCKET INSTEAD OF A BIG "FITSALL" WRENCH.

Adam, how do you REALLY feel?

I bought a school bus yellow parts truck with a purple painted diff cover once

. I'd say if that color combo is on your short list, go with chrome!

*1972C10* · 06-02-2004, 12:54 PM

I have had to weld stuff onto stripped fasteners all the time i have a friend of mine thats running around with a 3/8 extension welded into his plug on his 10 bolt in an isuzu

**COBALT** · 06-02-2004, 01:52 PM

The plugs Chevy Duty sells will fit. That's where I got my replacement when the flange started breaking off.

Well I do realize that chrome diff covers alone can add 5-10 rwhp... However I just don't like to take teh time out of my busy schedule to polish them.

Seriously, those chromies are weaker than stock diff covers...when I got my dana 60 front, the stock cover was dented so deep that it almost touched the ring gear. I guess I will have to build a custom thick one.

Also, a guy on Pirate 4x4 built a diff cover for his Eaton out of a sewer pipe endcap (not chrome

). I think I am going to do something along those lines myself.

Well I think they are kinda cool. I intend on putting them on my 4x4 since the the diferentials kinda stick out it's so high. I'm not gonna worry about my 2wd as you'll never see it. Sorry if you think it's GAY but your entittled to an opinion.

1969 GMC · 06-02-2004, 08:15 PM

sorry bout that, didn't mean to bash ya...I just think they're gay cuz they aren't as thick as OEM (which isn't that good anyway, IMO). I also dislike when some people want to make their entire vehicle out of chrome, which yours obviously aren't. But I'll shut up now.

No hard feelings.
