Great stuff. Thanks for letting us watch

great video. I have never built a transmission of differential. But it is mince to see how a professional builds one.

Great video. we just put posi in our 8 inch on our 62 Mercury Meteor with 3.80 gears.

Nice to watch this. Your friend is great and knows his stuff👍👍

Thank you for(d) this clear and helpfull video. I’ll be doing my 8” ‘66 mustang diff soon so i am glad to have seen this. Not only how to do it but also tips on what to watch and be careful with. Great!

Love the video. You guys are great teachers?

That looks like a great set up if you are on a budget and aren't planning on big HP, if memory serves the 8 and 9 inch rear ends use the same axles.

Agreed, this one is pretty stout for this particular car.

I’ve watched this video probably 15 times end to end. I really want to try it myself, but nervous bc I don’t have a bench Vice.

for a small block Mustang 1965, I have never broken a 8" differential. And I have only owned standard transmissions.

Very informative video. Thanks for taking the time to do it. One question. I just rebuilt an 8in this weekend for my first attempt. In the kit with all the new bearings it had a new crush sleeve. But upon disassembly it didn't have one. So i didn't use it Now i cant sleep because I think i messed it up. What do you think? Thanks

Any update on this? What type of transmission did your car have? I'm swapping my C4 for an AOD, so trying to decide between 3.55 or 3.80. Mainly for street driving. High revs on highway was reason why I upgraded to AOD. Thoughts?

Just put a complete rear end assembly 31 spline posi 8.8 in it for the same price as a rebuild.

Nice video! What is the part number for that nice aluminum pinion carrier? I can't seem to find it on the Quick Performance web page.

Great instructional video, but you never showed or explained how to check and set pinion depth. Can you do a segment on this procedure?

Great video thanks for posting. How is the axle holding up nearly a year on? I would love to keep my 8" but I keep reading different power ratings online. Curries told me 300bhp max but not sure if this is their way to push the 9" axles they are selling. What power are you currently running through yours

Thanks David, the car isn't going serious racing but the 8 inch is fine if you don't plan on putting serious HP to the rear wheels. I think this set up is good for 400 to 450 HP. Hope all is well with you.

Do these not have an oil slinger being the seal?

Didn't see the adjustment of the threaded ends on the carrier bearings. How is that adjusted??

what if i ve forgot to mark before disassembling?

Why does the kit have two crush spacers? Like the one that’s on pinion?

I am trying to find what rear end I can swap into a 1975 ford maverick that has a 5 bolt 8 inch rear end. I am hoping to find one that comes with disc brakes.

Keep looking around at comets, mavericks and monarchs/Versailles. They sometimes has 9"s you can swap directly in. Keep looking.

Great video except for one thing. What the heck is that piece you have in the small bearing. The area you cut off because it was to close, has a small bearing right next to it, but what the heck is that in the bearing now?? I have the bearing in there with the lock, but I dont have what ever that piece is in the small bearing you have. You got me worried now, help!!!!!

What exactly are you running for an engine in that car? What hp/tq? And have you gotten it out on the road yet? I have a 67 mustang with a 415hp/tq 347 , a c4 and an 8 inch rear. New motor, stock drivetrain. I may upgrade to aod but I'm not gonna put a manual trans in. Would love to stick with the 8 and do this exact set up due to the cost factor. This is a driver not a track car. Would love to know the results of this build and your opinion on the set up. I think these 8's are stronger than people think.

Jody, The car isn't on the street yet but for what my plans are this set up is perfect. I don't see any reason you couldn't build your 8" to handle your motor, as you noted they are way stronger then most people realize. If you aren't going to flog it at the drag strip and HP and torque are under 450sih this is fine.

@jodylane2045

Thanks for the reply. It's definitely under 450 and thats at the flexplate. I do like a good redlight burn out though.

Maybe I am not seeing this right? Are you installing the crush sleeve and then taking it back apart and re-using the same crush sleeve when you install the pinion seal? I don't think you are supposed to re-use a crush sleeve. Why did you not just install the pinion seal the first install of the crush washer. I have no doubt you guys know what you are doing. I just don't understand it. Thanks for the video and please don't take my questions as a knock.

He didnt reuse it. There was a new one in the kit. They put it on, and when they tightened it, is was crusked, hence the name crush sleeve.

Is the drive shaft still gonna be centered? Third member looks offset.

3.55's are a happy medium if you are running a standard 3 speed automatic as in this car. A nice step up from freeway gears without ruing the daily driver feel. If you are putting it behind a 4 speed or 5 speed there is room for a more aggressive ratio.

I never understood why anyone would run the 8" rear! I'm just going by personal experience with completely stock ones. They didn't last very long under hard use,whereas the 9" were way more dependable, even completely stock!

@MustangConnection1

Robert, As I stated in the video( I know it's a long one but hoping to help others) this is the first 8" I have ever built up like this one. The idea was to keep more of a budget build aspect while strengthening whats there. It won't be a high horsepower build at this point and that set up is more than strong enough to handle what the car will be doing at this point. Additionally literally millions of these units were put under 289 Fords so they are plentiful and not everyone can afford to sling a 9" out back.
