i've done more than a few gear swaps myself(successfully), and even i picked up a couple things from this video.

Setting a ring and pinion always seemed like black magic to me before this video. Thank you for doing such a thorough job teaching us.

Yellow bottle making fart noises, is the best was to start any video on KZread. This is an excellent video for upgrade carrier or gear ratio change. As he noted, this was a 3.08:1 ratio. Meaning the drive shaft turns 3 times to every turn of the wheel. Most people come in when they have noise. Changing the gear lube and kept at the correct level is important. I wish the quick lube guys knew this instead of trying to find a $46 PCV valve. The ring gear tosses gear oil thru a tunnel cast onto the pinion breathing’s, as we discussed a ready turn fast and ran somewhat low, will wear quicker. If this is the case, when apart, clean the metal flake out. Don’t forget the axle tubes and outer bearing wells. Spray carb cleaner followed by a rag, pushed inward with a broom handle. The worse it is, rinse & repeat. Air check the case vent on top to make sure it breathes as expansion & expansion occurs has to go somewhere, instead of seals. The outer axle bearing wells do hold gear lube so add some while installing the axles. When full, during long off-ramp turns, gear lube will fill these pockets by centrifugal forces. 1 more reason the keep the lube clean and full while level. Some companies manufacturer expensive high-tech rear covers that drop the temperature of high horse power and pulling trucks. Just keep in mind the most all us, realize that high temperatures break down and destroy man-made additives in GL-5 and others. As one of the best diff videos on KZread, there are a lot of things to think of. So, if the pinion seal starts leaking on your parking spot, think about the consequences of not fixing it... or least taking your bottle and make fart noise. My question is, who put the muffler in that spot?

GM put all Camaro mufflers in that spot, all generations. Duals are aftermarket.

Always enjoy watching Davin work and the way he explains everything. You can tell he takes pride in his work, and passing on his knowledge. My father always told me this, " You can only keep what you know, by giving it away".

I think you are over estimating the ability of most people to set the gears up right. I loved to see the spacer you made to run the truck seal. I set up one set of gears for my 70 chevelle 12 bolt about 10 years ago. I was paranoid that I didn't get the bearing preload on the pinion right. I had a old timer look at my work and said it was about right. A video like this would ensure it is done correctly. Thank you for the content.

I watched this video at least 50 times when I was redoing the 12 bolt on my Chevelle. Thank you so much for giving me the confidence to get the job done!

Between you guys and Ericthecarguy, our knowledge has been enriched, our confidence boosted and our appreciation is beyond words. Thank You!! If I am ever up against this task, you have my back. We all should aspire to help others like you and Eric have done over time. Cheers! Zip~

I really like Eric the car guy also. But, I watched his video on this subject and didn't see him measure the pinion depth. Which I feel is very important. I'm getting ready to put a Yukon in my truck and have been doing alot of research on this subject. This video here in my opinion is the real deal.

Amen brother!knowledge is power

I can smell the gear oil! I raced a 12 bolt setup back in the 80s (Moroso Brute Strength center) and was taught that the seal should be left out, bearings lubed with gear oil, moly lube or grease on the pinion nut and washer (to make the crushing easier and preserve the pinion threads), crush the sleeve to spec, (with a Snap-On dial style torque-meter if you have access to one) Once at spec, back off and torque the pinion nut to spec, recheck drag - creeping up on it if needed. Once the preload is set, dis-assemble to install seal (lubed with gear oil and a little sealer under the washer), then re-torque to spec. If all was well, the preload was accurately set without the seal drag effecting the setting, but you could recheck the drag and it usually went up 15-20 in/lbs with the seal in place. I always did it this way, and I'm sure you can get away with setting it during final assembly like you did, especially on a street car, but this was the preferred method according to GM and Richmond Gear back in the day. Hope it helps. Great video

I love all the detailed information that is included in this video. Other shows would have had this done in 10 minutes of video and glossed over all the important details. Keep up the good work.

You are a very good instructor . You were thorough , precise,and explained everything to the smallest detail that alot of instructors skip over ! Thank you and I will keep this video as future reference .

By far the best video on R&R of a 12 bolt axle set. I have a watched a few and have actually done gear changes on the 9" Ford so the concepts carry over. Very well presented in easy to understand terms and instead of spending hundreds of dollars on checking tools you provide a $2 solution. That alone was worth the watch.

🧰🔧⚙️🔩I KNOW FOR A FACT THE HAGERTY YOU TUBE CHANNEL IS THE SINGLE MOST INFORMATIVE CHANNEL ON THE TUBE! Quality info that is explained by someone with dirt under his nails not brooks brothers on his feet! I appreciate all the time and effort everyone at HAGERTY invests in making this kick ass channel

Thanks for this video. Rebuilt my GM 8.2 in my 71 Chevelle. Went with 3.73 gears and Eaton Posi. It was a success thanks to you guys. 🤘

That was the clearest explanation of setting the pinion shaft I have come across. I had a new Yukon rearend put in my truck from reputable repair shop and it whines to no end. I know now the pinion shaft is not set correct. Looks like I'm going to fix it myself.

Early on, I could tell that this was the most practical/usable Hagerty video that I have yet to watch! I had NO idea that the rear seal included in kits these days was a truck seal - that explains the pesky leak I never seem to get rid of - thank-you, thank-you, thank-you for taking the time to speel this out, and give a viable solution!! I also really appreciated seeing how Davin chose to set up bearing preload, it was so simply, it was a "DUH" moment for me!! Thanks again!!

This is the best how to do video on automotive repairs I have seen to this day. Specifically on rear differentials and gear changing, up grading axles, or even carrier bearing replacement. I don't know how much was scripted or edited but it was perfect. The explanation from start to finish was for the everyday person, camera filming was clear and on point. They say the Devil is in the details , so when you took the time to show the torquing of the bolts and ramping up in stages to final specified numbers was one of those details where in other shows and videos they skip all the time. I liked your fix for the pinion seal. For most of us without a lift I'm guessing will most likely not have a lathe as well, but you gave the solution we can get a ring or collar machined. I have been a mopar person my whole life and have been spoiled by choice when swapping gears. I would intentionally buy cars with the 8.75 rear end, mostly because it is the best choice for any car with any horse power plus the ease of maintenance. changing the gears is a piece of cake which the 3rd member comes out as one piece, just like the Ford 9 inch. That is really swapping out the pumpkin not breaking down the unit and changing to another ring and pinion like you did in your video. In the past I would swap rear differentials before attempting to change out a set of gears in Dana rear end. Your video has changed my mind about doing a gear swap on a 10 or 12 bolt gm rear end or Chrysler 7.25 or Dana 60. Keep up the good work on your videos. You were being nice to the new gears and bearings in your burn out right?? I hope so, for a big block on street tires, those should light up and spin until they pop or you let up off the gas. I would think that the life span for the rear tire would be greatly diminished after the posi installation and the lower gears. I was hoping you were going to show the RPM at 60 mph before and after with the new gears and tires. Also was hoping you were going to put in the new speedometer gear and go over the rule of thumb for ratio of teeth when swapping to larger tires and/or gears. Maybe a quick follow up video?

for heating bearings a electric skillet with whatever oil is laying about can't be beat. good thermostat to maintain whatever temp you want.

I did this whole thing twice back about 30 years ago, he nailed quite of few mistakes I made, and learned from. Spot on!

I drove my old truck for 13 years with the rearend seal leaking just enough to coat the underside of the bed with gear oil. Never enough to worry about... Now I wonder I had that same seal issue. Thank you for all you do! These are absolutely priceless.

Great video! I did this job with the rear end housing on the bench, and was glad I did it this way. I took the time to install new axles/bearings and installed new coils springs, shocks, and a rear disc brake conversion. I took my time and it took me a day and a half. I would not have wanted to do this with the housing in the car.

I agree with prior comment, this is by far the best instructional video on changing your ring & pinnion and setting up your carrier assembly. He uses language we can understand and explains when each step is completd & what it MUST look & feel like. Thank you!

I've been looking at diff rebuild videos for months and this is by far the best. Thank you!

I think, this has been the best explanation on how to rebuild or lash rear axles. Well done guys!!

ive been a diesel mech for 35 years ive set up a few diffs in my day this guy knows how to do it right. And probably the easiest way

Jerry - It's our pleasure! Thanks for being a fan.

hands down one of the best step by step out there!!! please do more of this!

When I changed gear ratios in my 69 SS Chevelle way back in 74, I removed the plates and springs that lock the wheels together and had a heck of a time compressing the plates together and inserting them. The shop manual showed using a couple of C-clamps but they had to be released to get the plates back in. SO, I compressed the plates and springs together with clamps and then tied the plates together with many loops of fishing line through each of the springs. After inserting the plates/springs, I cut the fishing line and pulled it out!! Worked like a champ!

I vaguely knew how to work in a diff, now I see what all is involved. Outstanding job, thank you !!

By far the best instructional video on differential upgrades. Thank you

What a wealth of information and knowledge. True privilege to bear witness to this. Thank you Davin.

Very thorough step by step learning process.

Thank you for making the video, now I know exactly what to do. A few years back like7, mu tear end had gone out on my way home from Columbus Oh to Pikeville Ky, I heard the roaring noise from the rear passenger side, stopped at a service station and looked under and seen the gear oil covered the inside of the passenger tire, this made it the second time I had to go inside that rear end. So I limped my way back home and the next day went to the boneyard and got another complete rear end. Ok here is the issue, my F150 is a 2004 V6 auto/overdrive. The option I had at the time was to take a rear end from a 97 F150, and a V8 I know a big gap in years but I had no time and it was Christmas Eve so I went for the brass ring, and this rear end has drum brakes. and everything on it in good shape, took me 45 minutes and $80.00 out the door I go. I went to my friend's shop and got busy, Within 2 hours I was on my way home. The boneyard rear end is a Dana 60 ratio I think it is 308, like your project my odometer is off and my OD is good at low speeds but at freeway speeds, you can't feel the difference when I shut the OD off. Would change speed sensor fix my odometer?

That was amazing, I could actually do the job right using this. The metallurgy comment about temp and discoloring is very valid though, you will get the desired expansion at much lower temps without hurting the bearing.

I found out that an old Hot Rod magazine had a rebuild and set up for a 9 " Ford pumpkin. It's really full of 90 wt,now. I can smell it in my sleep.

Ran into that seal problem before and a speedy sleeve similar to the one that saved my harmonic balancer saved the day. Not only with a wider, locatable too, sealing surface but in the future neither of us wept again.

Just loved the video and the way you explained it in detail ! Really great job 👍😀

Holy moly, outstanding video! I wish I would have had this a day ago now, bummer but I actually know where i screwed up....net time I will know bettter, the best video step by step in explaining.

I’m loving this. Please more Hagerty DIY tutorials just like this.

Having done this on many diffs I remove like you showed. To get the pinion flange off sometimes you have to use a 2 jaw puller to get them off. I like your way of measuring the pinion height. I have always fought them!!! Though heating bearings I do not like. They press on easily, Just get some pipe to do so. Fitting the ring gear on,, use some heat, 100F is usually enough. On a hot day leaving them in the sun is enough. Use a couple of cut off bolts as guides. And many ring gears only go on in one position. Check before trying to fit. I have never struck a short seal, though have never done a 12 bolt!! Crush sleeves, You can get 10thou shims to go under the old ones so as to reuse. You dont go through your exercise!! And make sure you have plenty of oil on the bearings. I have an alternative to your tool to hold the pinion. A piece of 2x1/4" with a swing piece to go opposite. Works trick. A dial indicator is ok for someone doing it the first time, I do them and bearing preload by feel. 3-5 thou more backlash is required for racing applications. Those gears get quite hot. Synthetic oil keeps them far cooler. And makes the gears live longer. The paint pattern is the drive side of the gear, you have showed the back! Check the oinion as well.

Very good video for a mechanic to follow on rebuilding a rear differential, one thing I would say though, if you go that far you should change the axle seals too.

So detailed! I enjoyed the video a lot, please keep the great work guys.

Absolutely excellent quality video with great step by step explanations and tips !

Geez , great job sir , you are so patient and very and very knowledgeable and the details are most excellent !

Great video! Thank you. Perfectly explained, and simple. Shows how to accomplish a differential change, with tools we all have.(Except the pretty little digital in/lb wrench!)

Great teacher To the point no fluff Explains tools required and giving proactive advice as you progress into the project

Great video brother. Great description on setting pinion depth. Wouldnt believe how few guys get the tooth wear pattern correct. After rebuilding mopar diffs I see why chevys are always breaking, everything is small. Ring gear pinion bearings. Great teacher my man.
