Alf's Mustang Garage is not responsible for any mechanical or technical error that you may encounter when working on your own car. You are responsible for your own quality control and your own proper repairs.
Today at Alf's Mustang Garage we bring in a 65 Mustang Fastback with a rear differential howling. Turns out the pinion bearing pre-load is too loose and needs to be reset. We remove the pinion support from the third member, replace the crush sleeve and set the pre-load. This is all done on a 8" Ford.

Love love love this beautiful Mustang. I cannot get over how clean and shiny it is underneath, wow. Great diagnostic skills! Thanks for sharing.
Oh ya this car is crazy. The owner did an amazing job in every aspect of the car. Of all the cars I work on, this one makes me the most nervous.
@@AlfsMustangGarage The best thing about it,, it is NOT a trailer queen!
Absolutely! This car does get on the road and is enjoyed.
Just found your channel. I am trying to catch up on all your videos. Just getting ready to install a 3rd member now. Ii started restoring a 1965 Comet Cyclone 2 years ago and didn't have your channel available then. I saw some mountains in the background of your video and recognized them. I live in North Ogden around the corner. You are going to keep me busy . . .
Ha ha what are the odds? Thats very cool, glad you found me. Ya there are a lot of videos now most of which are relatable to the comet. Let me know if you need any help.

I put solid sleeve from Currie in mine. Never have to be concerned by assembly or engine torque over stressing it.
I prefer the Eaton TrueTrak gear type posi. Very agressive and very smooth. Must use plain mineral lube. No synthetic, no slip additive... Either reduces the posi bias.
I always install a magnetic drain plug for easy routine oil changes.
Excellent tutorial. I will doing this very job this week on my 66 mustang 8 inch. Can you give the part numbers for the crush washer, yoke seal and carrier o-ring? (Would save me a little research). Thanks again for your great videos!
Wow, Ford pinion preload is much easier to set than a in a '65 Chevy...I just had the yoke nut back off of my '65 c10 and it caused the pinion to groove the carrier...what a mess! It turned out the right bearing had turned to dust which caused everything else to fail. Once I start working on my '65 Stang your videos will be my go to for how to.
Oh ya these are definitely much easier than the GM differentials. One thing that Ford did right 😅😅😅
First gen content 👍
Hi Alf, thanks for this detailed tutorial. Much onbliged from Amsterdam bye eric
You're very welcome! Very cool to hear from people all around the globe! Thank you for being here.
I love seeing that car!!
It is a nice car
Oh, dang! Just saw the parts list!
Great video man! Just sub’d 👍🏻🔥🔥
Awesome! Thank you!
Nice job!!
Thank you!
16:09 thats the same face i make when i drive my mustang :)
🤣🤣🤣
Nice, I got a 68 fastback with a swap diff since it was an original 4 lug but it's got a updated sway bar rear diff pretty big size still not sure on size but I'll be doing this soon.
Very cool! Love those fastbacks!
Should be a good ole 9in in her.
Hey Alf. Are the crush sleeves you listed compatible with an 8 inch diff? Says they aren’t compatible but I was wondering if they really are and Amazon was just wrong.
Your content is so helpful and it’s great thanks for doing vids.
I'm fairly certain that those actually do fit the 8" despite amazon saying they don't. Worst case, compare them before you open the package that way you can send it back if I'm wrong 👍
I'm going to your Amazon link to get the crush sleeve, even though it says it won't fit my 66 8 inch. Hope it does!
Amazon says out of stock, so it's off to Oriellys!
Oh dang it! I should send them some lol
Oops. Not the crush sleeve that's out of stock...it is the 8" seal (8181na). That's out of stock on your amazon link. Local parts store had one, so I'm ok there...
Hey do all 8" diffs DO NOT have an oil slinger between pinion seal and a gear? Doesn't it supposed to be there same like 9" does?
I don't know about all but every 8" I've torn down doesn't have an oil slinger.
My 67 has started doing this, can something like this cause a Hum/ vibration at 40-50mph?
It can. But so can many other things.
I've never seen bars attached to exhaust pipes like that before...what is this for?
I'm not 100% sure. I've never seen them either.

Hi, I recently added LSD and 3.55 gears to my mustang 8 inch. Initally, it had some howling when turning at slow speed and slight whine. After driving for a while (I guess after braking it in and bunch of figure 8s) howl and whine was gone. I drained diff oil, added friction modifier and new 80w-90 oil. It now makes a horrible ratchet clacking noise when turning slow. Both sides. Straight sounds just fine. Only turning at slow speeds. All I did was drain and fill oil. Any thoughts?
Sounds like there is something wrong internally. Probably want to take it out to inspect.
@@AlfsMustangGarage I was worried about that. It was going to be a while before I opened her up, so I reached out to Quick Performance (where I bought LSD n gears), and they mentioned that they've had other users call them about similar troubles when using "inferior /off brand additives" sold in popular parts stores. He said to use the Ford Motorcraft additive friction modifier instead. So I drained some oil, added the 4oz bottle of Ford Motorcraft additive friction modifier. Drove it around for a while and the ugly sound is gone. It's back to normal. Yay! 🙌
The one I had used that cause the issue was LubeGard Limited Slip Supplement. 👎
Oh wow! Good to know thank you for the advice. I'm about to build one myself for a 67 cougar. I will remember this.
Last quick question. I have no clue as to the mileage on my 8 inch diff. I am assuming quite a few thousand miles. Without the manual in front of me, what should I set my preload to?
15 inch lbs for used bearings is what I usually go for.
@@AlfsMustangGarage that crush sleeve is a bugger to crush! I know I'm a pretty good bit above 175 ft lbs on the nut (breaker bar and cheater pipe) and I'm seeing about 6 inch pounds preload. It feels much better than it was when I took it apart, but I'm reluctant to put anymore torque on the nut for fear of doing something bad. Is this normal?
Can this be done with a regular torque wrench?
No. Not if you want to do it right.
