Re: I need a 9 bolt oil diff plug
 

I bought a NOS one recently. Found it at some dealer out west through partsvoice.

Re: I need a 9 bolt oil diff plug
 

I can't find one anywhere

Re: I need a 9 bolt oil diff plug
 

Try one for the Dodge truck rear end. Some Jeeps use a plug like that too.

Re: I need a 9 bolt oil diff plug
 

I scored one on Ebay a couple years back, was 25 freaking bones for cheesy rubber plug lol.

Good luck!

Re: I need a 9 bolt oil diff plug
 

Yes, your GM number is correct.

Just get the TA aluminum rear cover. Problem solved.

Re: I need a 9 bolt oil diff plug
 

I do see a new cover on a few of those sites with a screw in plug are less than $30 bucks and chrome too!
I got my plug a few years back in the Dorman/HELP section of the parts store a few years back for less than $5 bucks.

Re: I need a 9 bolt oil diff plug
 

I have a 9 bolt rear end
I measured my hole it's. 80 "
Not 1.3
I stood in Napa today for 1 hour found nothing

Re: I need a 9 bolt oil diff plug
 

I live in Canada

Re: I need a 9 bolt oil diff plug
 

http://9bolt.com/ might be able to help you.

Re: I need a 9 bolt oil diff plug
 

A quick search on partsvoice showed that Craig Motors in Napa, CA has one in stock. Call them at 800-224-8111 and see if they'll ship it to Canada. Hurry up, because I might buy it if you don't. :p

Re: I need a 9 bolt oil diff plug
 

I welded a large nut onto my cover, maybe 3/4". Worked great. Made checking and adding oil a cinch. If you can't weld just take it to a welding shop or call a side welder from one of the Craigslist ads. I would think the bolt and weld would run you $20.

Re: I need a 9 bolt oil diff plug
 

Actually, I'd measure the hole, then jump on the Google, and do a search for something like "Rubber Cap Plugs" and fish through the results until you find someplace that carries a plug that looks about right, and says it'll fit a hole that size. You might have to order 10 or 25 to get something really close, but I'll bet you can find something close enough. If you want to be belt plus suspenders kinda guy, stick with auto parts suppliers or make sure that whatever plug you find is "Oil tolerant" "Oil resistant" and rated for outdoor exposure.

.80" works out to somewhere between 3/4" (.75") and 13/16" (.8125). So maybe try something like "Rubber oil drain hole plug 13/16 inch" for your search string.

Because here's the thing... Borg Warner or GM, whoever in the business of building axle assemblies and cars, didn't go out and buy a rubber plantation in South America and build a processing plant to manufacture differential cover plugs. They went to a distributor and bought X qty of rubber hole plugs. You can do the same, you just have to work within the limits of what's available. GM is out, that distributor probably still makes the exact same thing or something similar to plug holes in piggy banks or mouthy ex wives...

Re: I need a 9 bolt oil diff plug
 

I'm just gonna have to welds bung
I ordered a new 9 boktgasjet here Tuesday
A d then I'll take it off and weld a bung
Is it ok to seal it up
Does it need a rubber plug to vent extra pressure hot cold stuff

Re: I need a 9 bolt oil diff plug
 

Nah, there should be a vent elsewhere in the diff for venting. Not sure where it is on a 9-bolt, but on the 10-bolt...

https://cimg5.ibsrv.net/gimg/www.thi...e9ff623082.jpg

On the Ferrrd 8.8 is on the top of the right side axel tube...

https://cimg7.ibsrv.net/gimg/www.thi...10c21af245.jpg

Haven't got a 9-bolt handy but it's surely got one.

The rubber plug is just fast and dirty, fill, plug, pull plug, check level, push plug back in.

Re: I need a 9 bolt oil diff plug
 

I have the TA Aluminum rear cover and it has regular screw in plugs. No cover venting required. It's a nice piece with carrier bearing supports.

Re: I need a 9 bolt oil diff plug
 

Ok th great
I'll do the welding bung
Ty

Re: I need a 9 bolt oil diff plug
 

I'd suggest just tapping it to pipe thread. ½" NPT if memory serves. Then use a brass plug with Teflon tape.

Re: I need a 9 bolt oil diff plug
 

Not so easy. Last time I tried to extract the plug it ripped in half. This was back when you could just go to the dealer and get a new one. I just drained and refilled my 9 bolt yesterday. Pop off the cover and push the plug out from the inside to avoid damaging the thing. New 9 bolt gasket from rockauto.

Re: I need a 9 bolt oil diff plug
 

I don't think this will fit. the neck on the GM plug is longer.

Re: I need a 9 bolt oil diff plug
 

Has there been any resolution to this? Is the solution to Weld a nut onto the cover and use a plug? Tapered pipe plug?

Re: I need a 9 bolt oil diff plug
 

That is still the solution in my world because I have the ability to weld. If you can't weld and/or you don't want to pay someone to weld on it then your next best bet is a body plug or boat plug.

Re: I need a 9 bolt oil diff plug
 

Don't forget the TA Aluminum rear cover. I can weld but hey - it's a nice piece they make for us "weird" 9 bolt people. Worth the price IMO. Make sure to use sealant on the carrier bearing support/preload studs. Mine leaked through the threads. Loctite 545 solved it. Wasn't in their instructions though.

GD

Re: I need a 9 bolt oil diff plug
 

that thing is expensive. As long as my stock cover and plug don’t leak I’m good.

Re: I need a 9 bolt oil diff plug
 

$160 is expensive? News to me. That's CHEAP for quality parts. Subtract the time and expense and frustration of the factory rubber plug from that. What? $100? **** man that's an evening at the local Chinese choke and puke for a family of four.

Seriously that's cheap. And it makes draining possible without pulling the cover, adds carrier bearing cap supports, magnetic drain plug..... and it comes with a gaskets. So subtract the cost of that also.

GD

Re: I need a 9 bolt oil diff plug
 

Exactly,
It's not just a "cover", it has other functions you don't get from a stamped piece of metal. It also aids in cooling

Re: I need a 9 bolt oil diff plug
 

Gale Banks did some good videos on his YouTube channel of aftermarket covers/girdles/supports that might interest you guys.

Re: I need a 9 bolt oil diff plug
 

I saw what you did there. Stop doing that. Stop enabling the low quality posts around here. I HATE HATE HATE when people can't even be bothered to spell a 4 letter word correctly. They are here to ask a technical question and don't even have the spelling ability of a 3rd grade student. :gocrazy:

Re: I need a 9 bolt oil diff plug
 

I had seen part 1 and one of the other videos before this thread. Just watched part 2, not really a whole lot of info given in them with supporting/documented proof of whether the covers he is featuring are really negative designs or not. I like his approach to what he is getting at though, but I really want to see the evidence on whether the covers do/do not work as the respective manufactures suggest.

At any rate, we are talking about the TA Performance girdle, it's not just a cover. And it doesn't appear that Banks is doing any videos on girdles, just covers. At the very least, the TA cover should help reduce temps of the oil, since aluminum is more thermally conductive than steel, it also provides an easy fill/drain/level of the fluid when doing maintenance/checks. Also, from what I remember, the inside of the cover is shaped similarly to the stamped steel design, so the fluid movement should mimic the stamped cover, as designed.

I will say that I think Banks is over thinking that the manufactures, of stock covers, are putting a lot of design thought into the stamped steel covers. I think there is room for improvement, but the design is mostly out of concern for cost of manufacturing. Just my opinion though, I could be wrong. I wish Banks would release part 3 video already so we can see some evidence of what he is saying about the other aftermarket covers

Re: I need a 9 bolt oil diff plug
 

LOL 90% of the time, the accuracy of my spelling and attention to spellcheck is impeded by the large yellow cat that likes to take up residence between me and the laptop. Simple typo, no offense intended. ;)

Oddly enough, Ferrrd placed the vent on the Explorer 8.8 on the Driver's tube, just so the extended tube up to the frame would be in the way while servicing the fuel filler neck. Them bastards.

Re: I need a 9 bolt oil diff plug
 

LOL. I see posts all the time from wrench heads, here and on some Facebook boards, who appear to be severely spelling challenged. Even the simplest of words get mangled. Oh well. And I well know the hazards of a friendly lap cat who decides he wants attention jumping up right in the middle of what you are doing. It is what it is.

Re: I need a 9 bolt oil diff plug
 

What? You mean my Eldorbach Crabberaytor or my Weeind intake? How about the head and cams in my Chevy? Sorry, I'll stop now. :)

Re: I need a 9 bolt oil diff plug
 

Drew is a very intelligent person, arguably one of the sharpest members here. He also likes to be the lead troll LOL. I'm obviously passing a humorous reprimand his way because he sits in the back making fart noises while some of the rest of us are trying to class the place up a bit.

Re: I need a 9 bolt oil diff plug
 

If one person laughs, I've done my job to brighten someone's day. ;) I'm almost... almost positive, it was an unintentional typo. But after scrolling up to see I typo'd the same misspelling from the OP, it gave me a laugh.

Literally half the time I'm trying to type with one hand while not disturbing the cat. He absolutely takes it as a personal affront if I'd choose to say.... operate a mouse, or use my hand to hit the backspace key to correct a typo, when I've been exclusively chosen to scratch him behind the ear, or rub his face. I won't say he's difficult, but spoiled might be appropriate. At least he's stopped sending cryptic messages to friends and family on Facebook. Which is to say that he's stopped sitting right on the laptop. He just still chooses to insert himself between me and anything that would compete for attention. Teenage cats, what can you do? :totopic:

Re: I need a 9 bolt oil diff plug
 

He just released his last video on that series. Search YouTube: how to engineer the perfect differential cover by Banks Power
Can't link to YouTube because I'm at work. :gocrazy:

Re: I need a 9 bolt oil diff plug
 

For future searchers.

9 bolt diff plug.

Dorman HELP! 65293

Re: I need a 9 bolt oil diff plug
 

I watched it on Facebook. It was good, they really went into testing in detail. They could have released a video of the shortcomings of the flat back covers and then released another video showcasing their cover and it's superiority, instead of making us wait.

Re: I need a 9 bolt oil diff plug
 

ATM hes also only making that cover for a single rear end. I am really hoping that he will make them for other mainstream rear ends like the Ford 8.8, + 9" and Chevy 12 bolt, especially with him giving them a lifetime warranty. I think the Ford racing aluminum cover for the 8.8 with it's internal vertical ribs is the closest thing to his cover.
