I was in the automotive business for over 38 years , I have done plenty of differentials in my days , what you looking at in this KZbin is a textbook differential assembly , this is the way I did it the mechanic shop way the easy way . 1st ; Ring Gear Carrier bearing preload , the first thing I will do is Ring Gear carrier preload before I even install the pinion gear in the case , I will drop the gear carrier in the case and lightly tighten the bearing caps holding the bearing in place ,after installing the Ring Gear and carrier I will use a rubber mallet and smack the front of the ring gear couple times then the back of the Ring Gear couple times making sure that the ring gear adjustment shims have settled in their place , then tighten the bearing cap bolts to specification and check the preload , at that point I know exactly what size shims I have to use , all what will be left is swapping shims until the right contact point and backlash between the Ring Gear and pinion is achieved . 2nd ; Salvage the old Crush sleeve or shims whatever you're using , install the pinion gear without the oil seal using the old crush sleeve ,(unfortunately oil seals on the market are not exactly all the same , and some aftermarket oil seals will apply additional drag on the pinion gear preload adjustment ), Install the flange yoke ; tighten the pinion gear knot just enough to hold it in place , keep in mind that the new crush sleeve will only give you one chance to get it right , and that's why the use of the old crush sleeve can be extremely helpful ,install the ring gear carrier and set the contact point between the ring gear and the pinion gear . (some Crush sleeves that I had to deal with made out of thin material that would easily Crush , others required extreme pressure before it begins to crush , therefore salvaging the old crush sleeve is an option that might come handy ) . If the crush sleeve was manufactured out of thick difficult to crush material ? I used to do some measurements and get a rough idea of how much Crush did the job require , then using the hydraulic press reduce the size of the crush sleeve leaving behind a small distance to be crushed after installation in the differential . therefore adjusting the pinion too ring gear backlash and contact points will be easily achieved without fighting pinion gear preload with the oil seal drag on top of it , if the differential you're working on uses shims instead of a crush sleeve then you are in luck , it is possible to adjust pinion gear preload to specifications without worrying about the final installation in which the oil seal will impose additional drag on the pinion gear preload adjustment , this way after you are done with all of the adjustments you could easily install the oil seal without changing the pinion gear preload . 3rd ; after the final adjustments making sure it is where you want it to be , remove the drive shaft flange yoke off the pinion gear and install the new washers or the crush sleeve , install the new crush sleeve and the bearing then install the seal and the flange yoke , all what you have to do now is get the proper pinion gear preload keeping in mind that the seal is fighting you back . there was times where the crush sleeve was made from thick material and I had no option except to used the hydraulic press and crushed it to a light preload , after finishing all the adjustments that was needed , I installed the oil seal and all what's left now is just a small amount of Crush sleeves preload , do not use air impact gun to adjust the Crush sleeves preload , it will crush too fast and you will lose it . Warning and if you words of caution and good practice . A used differential will require a larger amount of backlash , for example your dismantling a differential to replace a pinion gear shaft bearings , make sure to measure the amount of backlash on the ring gear and pinion gear before dismantling it , upon reinstallation it is ideal to get the backlash to what it was prior to dismantling it , do not adjust an old used ring gear pinion backlash to the book specs that deals with the new ring gear and pinion , it will be too tight .

@Msonjo916 Hi, for pinion gears that use a crush sleeve, you do not tighten the nut to a specific torque, you tighten the nut until it takes a specific torque to rotate the pinion gear (all the bearings must be lubricated before doing this). There are some pinions that you do tighten the nut to a specific torque because they use selective spacers rather than a crush sleeve to set the pinion bearing preload.

Hi, the shims are selected by setting the side bearing preload first (with the shims) and then by adjusting the backlash (with the same shims). If you have no idea of where to begin, use the original shim thickness and go from there. I tried to explain all of that in the video. I hope that helps.

Hi, the new crush sleeve should be slightly longer than the old one because it is uncrushed until the pinion nut is tightened to the proper rotating torque. It is usually very difficult to tighten the pinion nut to specification because you are also crushing the crush sleeve at the same time. The crush sleeve provides the inward-to-outward force that holds the bearings in place when the pinion nut is tightened to specs.

@trucEtnA Hi, that is a good question. As long as you are using a new pinion nut with thread lock compound, a new crush sleeve or preload shims AND you only apply the brakes just hard enough to reach the appropriate loaded rotational torque at the pinion, it will not over torque the pinion bearings as you run the contact pattern.

@Msonjo916 Hi, without the special tools to select the proper beginning pinion depth shim, I would use the old shim, set the backlash to specifications and check the gear contact pattern. The pattern will let you know if the pinion depth or backlash need further adjustment.

Hi, you start with the old pinion shim(s), assemble the axle, set the backlash, and check the contact pattern. The contact pattern will tell you if the pinion needs to be moved closer or farther away from the ring gear or is the backlash needs to change. You move the pinion by changing the pinion shim thickness. There is a link in this video description for a gear tooth contact pattern interpretation chart.

There will always be those viewers out there that bash a posted video as this ( see a few posts below ) . But I totally agree with WeberAuto that it would have taken them a few hours to show all the different senerios with gear set up . Also I would agree from past experience ( incorrect pinion set up from a local licensed Ford Dealership ) which caused pinion failure on my truck's rear differential . That there are trained licensed technicians/auto mechanics that either take short cuts or just don't fully understand how to properly do a gear install .

Hi, the yellow gear marking compound "Paint" is used to see where the ring and pinion teeth actually make contact with each other. The pattern can show you if your pinion depth and backlash are set correctly. There is a link in this video description for a gear tooth contact pattern interpretation chart to help you understand the patterns.

I work in an environment where sometimes 3 ten thousandths of an inch is unacceptable and after my first gear set up, I was concerned... Now I understand it's not that big a deal. and I only have to work to the .001. I used Dykem for patterning and could see the difference between gear manufactures. I gave up and used white lith.

best explanatory video i have seen regarding the differentials. Sure the shown example was the perfect scenario, but there were more than enough info given what to do if you have abnormalities. And if people cant grasp that without being shown, then they really shouldn't rebuild differentials. Every diff is different, with different specs and different methods to adjust things, but the adjustments in principle are exactly the same and were very well explained.

Hi, there some expensive tool kits each vehicle manufacturer offers that will help you determine which pinion depth shim to use, but it is not exact. I have used many of these tools; we have them here for my classes, However, it has been my experience that these tools always tell you to use a shim that is within .001 inch of the original shim. Because of this, I recommend that you skip the expensive tools and just start with the old shim and then adjust if necessary based upon contact pattern.

MrRealP x, I can't answer your question if you do not allow comments on your comments in your privacy settings. Rotational torque is the torque needed for a constant rotational motion, not to tighten the nut or bolt. Yes, both need the torque wrench to ROTATE, but one stops rotating when you reach the desired torque, the other never stops rotating since is is measuring the effort required to rotate the nut and everything connected to it. I hope that helps.

John Dugger hello Mr John, I have a question on a Dana 80, is it possible to change the leaking oil seal between yoke flange & pinion shaft, without removing pinion gear. Or is this improper, one needs to fully remove differential install new crush sleeve and properly install pinion oil seal? I think I've answered my own question there's no shortcuts doing it the proper way.

@djsteve1987 Hi, When you ran the contact pattern did you provide some load on the ring gear as you rotated the pinion? I usually use a pry bar on the outside smooth part of the ring gear to make it difficult to rotate and then turn the pinion forward 5 turns and backwards f turns. (Assuming the backlash and pinion depth are close to spec) If you still do not have a pattern on both the coast and the drive sides, you probably have a bad gear set.

Hi, I don't have a video on those topics yet. To remove the ring gear, remove the bolts (be careful, some ring gear bolts have an "L" on the bold head indicating left handed threads). Use a brass happer or brass drift to lightly tap the ring gear off the differential case. You will have to heat the ring gear up in a toaster oven to 200 degrees F to reinstall it. Be sure to use the new bolts that come with a new ring gear. If you must reuse the old bolts, clean them and use red threadlocker.

You used a plastic hammer to install the shims I have seen the use of a case spreadera device that bolts to the case and a bolt to spread the case apart a tiny bit to install the shims then released to check the preload would that be better then using a plastic hammer to install the shims? Example >Kent-Moore J-45222 Axle Housing Spreader

Hi, good question. A case spreader is only to be used on specific Dana built axles, no other axle uses one that I am aware of. Even when using a case spreader, you must be vert careful to not spread it more than spec (typically less than 0.019") or permanent damage will occur to the axle housing.

WeberAuto Good point I knew that it was .015 but probably best not to use one don't want to damage the case. On another question preload on the carrier bearings could one use the axle to check the pre-load without the pinon installed? Normally most just check the preload overall with the pinon installed seems to me that the gear backlash, gear pattern, pinion depth all affect the ability to measure the carrier bearings preload.

Hi, once you remove the ring gear, the side gears and differential pinion gears should be able to be removed by removing the pinion pin in the differential case. If you have a locking differential, the side gears and pinions are harder to remove. Some even require a special press to relieve the spring tension on the side gears. I will work on those videos for the future.

Maybe the quality isn't that good. The rear differentials in two of my four GM 1/2 ton trucks are in need of rebuilding after between 230,000-270,000 miles.

thanks for that I look forward to watching the g80 rebuild and I looked in my glove box sticker and sure enough it says g80 on the rear axle and from the pics I've seen of them don't think I am ready yet to tackle that! lol Hopefully your video will prepare me for that later down the road after I learn the more basic hands on with the open type! again thank you very much for your help your the very best I've came acrossed! what got me so interested in this subject is I had 2 so called professionals rebuild rear axles in the past and they went south after about 6 months and a lot of the older retired technicians have told me that theres a lot more to it then most know and it got me interested in learning this lost art! iam very picky with my vehicles I strive for perfection on everything I do! again thanks for the lessons on this and look forward to the g80 video! and love your ujoint series too! I always wondered about people smacking the drive shaft ears with hammers made me cringe because I knew it couldn't be right! thank you very much!

This video has been very informative I watched the whole thing. Gotta get myself a dial indicator. Also very clean workspace major props on that. That place is like a hospital although it is a University so I would expect nothing less. Been an official mechanic for 5-6 yrs now, been turning wrenchs for over a decade and the internal workings of transmissions and differentials are things I'm really starting to get into and this video was excellent.Theirs gotta be a good way to load the diff for the ring and pinion tooth contact test while having the diff mounted in a bench holding fixture. If you really wanna teach about a crazy rear diff, grab a focus RS diff lol. Their isn't even any disassembly info or specs on the Ford PTS site.

hi John just wanted to say that I finally think I've got my drive axle noise pin pointed down I think it's the axle bearings because it has a growling type of whine that don't Change on exceleration or deceleration it seems to change when you on a straight away and you move the steering wheel from side to side the sound will change! it's ever so slight right now I have very good hearing most people can't hear it but one of my technician friends drove it and told me I was on the right track I am going to wait and make sure before I replace them i want to be double sure first! don't think it's the differential though I've had a lot of problems in the past with them and know the different sounds gears and bearings make and this sound is different then I am use to! thanks for all of your help and knowledge on rear axles I do fully understand how to rebuild a rear axle now but don't want to unless I have to because I believe you are probably stronger then me and I watched you get a good workout with that pinion bearing preload on the 1963 Chevy biscayne differential and I don't have the tools you have to work with but plan on getting some little by little so I am prepared just in case! your by far the best instructor and u want too say thank you very much!

Very informative video! I replaced the planet gears in my car a year ago since the previous owner had welded them stuck. Since I had no proper tools, knowledge and skill to adjust it properly afterwards I sent it to the dealer. A year later, now, it rattles, oil is black and a lot of metal particles. Turns out even the dealer couldn't set it up properly. Expensive lesson for them.

@jrstow86 Hello, In a perfect world that might work, but today's new replacement bearings are not the same dimensions as the old bearings. There is actually a plus-or-minus .003" (.076mm) thickness specification for some replacement bearings. This means that if you do as you say (grind the old inner bearing races) and then replace them with new bearings, you could be off as much as .006" (.152mm) to the left or right affecting your backlash and your side bearing preload.

Very good job explaining it all. Thank you. I did see the side bearings pre-load being measured a different way before do using the same torque wrench and a long extension with a special socket to go down into the centre of the differential through the drive shaft holes. the differential bearings preload are then measured but i guess technically this still takes account of pinion bearing preload as well

Excellent instruction, thanks for such a great video. I have a question: Is a small amount of gear noise common when running higher numerical gear ratios? I ask because I had a 4:10:1 Richmond gear set installed in my Chrysler 8-3/4" differential, along with a new Sure-Grip differential, and it exhibits a bit of whine under operating conditions. When I asked about this, the guy who performed the work rechecked his work, said all looks good, and added that a small amount of operating gear noise is not uncommon with higher gear ratios.
@WeberAuto
@WeberAuto 6 жыл бұрын
Thank you. No, it is not normal. Many vehicles come with 4.10 gears and do not make noise. Gear noise can be caused by improper bearing preload, pinion depth, backlash, or all of the above. Best wishes.
@NGH99999
@NGH99999 6 жыл бұрын
Thanks for your response. And thanks to your great instructional videos, I ran a contact pattern on the gears and, sure enough, too much pinion depth! At least I can move forward now with a new plan of action. Many thanks again for sharing your wealth of knowledge.

I had my gearbox with the differential properly fixed on my rear-engined and RWD Skoda 130. I did not have a new pinion and ring gears, as they are very hard, almost impossible to get. Also the wheels of the 5th gear were replaced completely, as they wear out fast. When drving there is a slight howling noise only when the load is small, when I need to keep the vehicle speed on a straight strech of road at moderate speeds. Driving faster makes the howling noice go away, as the foces transmitted are higher due to higher air resistance, drving slower is a lower RPM, when the howl is not yet in the correct frequencies to resonate parts of the car body, or the gearbox housing. Driving in 5th gear creates some additional howl, but that might be due to new wheels of the 5th gear and after about 500 km of driving, it got much quieter as the wheels wear in. Yet the diff whine remains and is the same in 3rd, 4th and 5th gear. Only when a small load is being transmitted. Coasting as well as engine braking is without any problems. The howl is most noticeable between 70 km/h and 100 km/h. A bit annoying, since those are the speeds I drive mostly at. Driving slower only in city and faster only on limited stretches of the freeway. Flat country roads, where I want to drive 80 km/h to 90 km/h are the worst speed to drive at. Any tips how to fix the whine other than replacing the pinion and ring gears?

Man what a kick ass video,i love technical stuff and you explain it so good and in detail,Ive been working on cars since i was a kid and i have rebuilt 5 engines in my life but i have never attempted this because i guess like most people I'm not that good with measurements and things of that nature,this video did help a lot though, i might attempt it here soon,i have a 8.8 on my toy that i would like to change gears on. i do work in a machine shop so i have all kinds of tools at my disposal.
