The two things I like about this video are 1) A professional mechanic lets it all hang out and we get to see the struggles. A multitude of pros would never dare admit they struggle with a repair or procedure. And 2) An opportunity to see complex processes like this so we can decide if we can take it on ourselves, or take a pass. The two places I continue to fear to tread, as a back yard tinkerer, are transmissions and differentials. ETCG - Thanks for all your efforts.

Did this 1 year ago, on a GM 8.5, installed a Yukon Duragrip and the old 3.42 ring and pinon 40 year old stock gearset. As Paul said it was a lot better doing it without a crush-sleeve . But it took me 14 tries, swapping out carrier bearing shims, and juggeling pinion shims around to get it just rigth. A set up bearing is a must! But an extremley satisfying job in the end when it all works great without a sound :)

Here's a tip for anyone doing rears that use crush sleeves. Crush sleeves or crush collars don't need to be installed during initial setup. If you set your pinion bearing preload lets say to 28 inch pounds. That will be the preload you will measure your setup distance or check your pattern against. Once you are happy with your pattern, then install the crush sleeve and crush it until you reach the same preload. The crush sleeve is necessary so that a torque preload is present on the pinion nut as well as a memory point in the event the pinion seal needs to be changed. In regards to carrier shims for backlash. If you are using the same carrier in the same housing measure the total height of both right and left sides. Record that number. However you juggle left and right thickness to obtain your needed backlash always keep that same stack height. This will assure proper carrier preload.

@ericthecarguy 8 жыл бұрын

Thanks very much for the input Paul. I'll be leaving the crush sleeve out next time I do a set up. I hadn't heard of that until the comments of this video and I did a lot of reading before I made these videos. As for your recommendation about the shims, I actually cover that in Part 2. Thing is, the Ford shim kit is very limited and that's so hard to do. I think this would have taken half the time if I had a shim kit similar to the one you used in the T-5.

@GearBoxVideo 8 жыл бұрын

+EricTheCarGuy Didn't the new ring and pinion come with a spec for distance? Often times people think they need a special tool for setting distance. The reality is your bearing caps split on the center. You lay precision flat ground stock across the saddles and use a standard depth mic.

@ericthecarguy 8 жыл бұрын

Nothing like that, but in the next video I share what I learned from Ford performance which is start with .024-.028 pinion shim. At the end of the day I ended up using the same one as stock. Honestly I think that would be typical for a set of Ford gears. IDK about the aftermarket ones though.

@GearBoxVideo 8 жыл бұрын

The Dana and the Ford stuff is pretty accurate. Some do a nominal measurement and then you'll see a + or -2 on the gear. Best to keep to OEM gears. Aftermarket stuff is all over the place. The pattern looks good. Can't wait to see the car come alive.

@markusstrobl1067 8 жыл бұрын

You're doing it the hard way. For setup you don't need the crush sleeve at all. Just tighten the pinion nut (without sleeve) until you have the required drag on the bearings. Also for the final tightening of the pinion nut (with sleeve) you can easily use the impact. It turns so slow due to the sleeve that you can set the bearing drag no problem.

@boomstickkid 8 жыл бұрын

nice video, but you dont need a new crush sleeve when checking pinion depth. only after you have achieved proper pinion depth and gear pattern and are ready to put the pinion in for good you can use a new crush sleeve. just use the old one for setup.

only when it has a horrible design towards setup. love my old landrover as it has the diff pumpkin as a seperate unit, no diff cover and you take the whole thing out as a unit, no shims on the diff carrier, only adjustable end caps. do them up to get perfect backlash and preload. pinion has shims that go on the other side of the bearing so you dont need to take the bearing off to change pinion depth. also making life a lot easier. take about 1-2 hours to change gear ratios and diff center on the bench. also ring gear is so close to not a press fit a swing with a hammer dropps the old ring gear off.

If the replacement gear set has the pinion gear mesh depth engraved on it, I use a depth mike and measure off the bearing saddle to achieve that dimension. Then, your heel/toe portion of the pattern should be pretty darn close to where you want it. I never use a sleeve when doing a set up, just enough pressure on the flange nut to keep the pinion gear from wobbling around. Never had a problem yet! Once I set up a GM 12 bolt Posi for a '68 GTO like a Dana, with a solid sleeve from Summit and shims to get the rotation torque preload to spec with 250 Lb/ft of torque on the nut. Worked out great! Something that was left out from this video and is VERY important, is to check the pattern and back lash at three places around the ring gear to make sure that you don't have any tight spots. A couple of dolts set up a new set of gears in a Ford tow truck axle, and didn't make it out of the driveway before the pinion gear blew up and took out about 1/3 of the ring gear! The reason? The cold chisel used to separate the old RG off the gear case gouged it, and the chip was left under the ring gear, elevating it about .007-.010". When the high point of the RG came around to the pinion gear KA-POWWW!!! Metal schrapnel all over the place inside! The Detroit Locker was also damaged and parts to fix it couldn't be had for 10 weeks, so a peg leg axle had to be put in to get it going and making money again. If they had bothered to check in three places, they would have spotted the problem and could have fixed it before the damage was done. Let that be a lesson to all here!

I have even expanded my search for either a Futara Coupe, or a Wagon. NO LUCK!😿 My only complaint I had with my (5) previous Fairmont's/Zepher's was the Aluminum Bumpers.

This is a good skill to learn! A diff overhaul around here will set you back over $2,000 - can save yourself ALOT of money, so long as it's done correctly of course. I had an '86 Grand Marquis (still do, but it's a different car from the one I'm talking about) back in '00 when I was living in Phoenix that developed a pinion leak. Replaced the seal, & bought a new nut. Didn't have an inch-pound torque wrench, so I had to guess! Funny thing on that was, anywhere I went looking for one, I got stared at like I had 3-heads. Apparently back then, inch-pound torque wrenches were a rarity. Anyway, I got it together and went for a ride. Nice and quiet at cruise, and under load. Perfect ... so I thought! Got off the highway and slowed from 70 MPH to 30 or so, and as soon as I let off the gas, WOOOOOOOOO (in a cascading sound as I slowed). VERY loud on decel. Knowing I wasn't supposed to touch that nut after tightening it (new one was $35 at the time), I loosened it just a hair and tried again. PERFECT! Learned that day to mark the nut and pinion, AND count the number of turns to remove the nut! :D

I thought of and discovered a really cool trick when installing races on a sport bike I was rebuilding. Take all the races and put them in the freezer for a few hours beforehand, then take them out one at a time as you need them. You'll find that the races shrink enough that they literally just drop in, maybe sometimes needing a little tap. It was a whole lot easier than having to press them all. A thicker bearing might take longer to shrink, might not work at all, but it's worth a shot.

I set up those crush sleeves in the press. On a live axle, you need a helper to get the rear end into the press and hold the end to balance it. Set the pinion flange down on the base of the press with a gap to access the pinion nut, and press on the pinion with a long extension. You can feel the preload on the bearings by the friction when trying to rotate the housing in the pinion bearings. Once you have it right, you can just reach up under the press base and tighten the nut down.

Those bushing/seal driver kits are a life saver. I use them for control arm bushings, wheel bearings and the like all the time. You wouldn't think they'd be strong enough since they're aluminum and so light, but they work a hell of a lot better than sockets. Also, that's why professional differential builders use large pneumatic impacts.

+EricTheCarGuy I agree with eustise. You dont need the crush sleeve during setup. You just have to setup same rotational resistance without the crush sleeve. The pinion depth will not change due to pinion bearing preload as long as the pinion is not loose. Once you get your setup right then you put in the crush sleeve during your final assembly.

Make a fake yoke out of some tubing and a nut. Make it a bit longer than the height of the yoke. For setup, leave the crush sleeve out and tighten the fake yoke by hand until you get the right preload. Saves a ton of time and you only need 1 crush sleeve to do setup. I see you fond the shim driver tool. I've got one drawer of my tool box with special tools for doing gears. They also make crush sleeve eliminator kits. Good luck against my buddies Miata on friday!

Incredible differential video. Well done! I hope I never have to do it!

Great video, Eric. I have done what you are doing and, yes, sometimes it is very time consuming. Unless you have done it, no one really knows how many hours it can take.

So eric loved the video. I am glad to find a detail video on a 8.8. I would like to ask you a question about my 2008 crown victoria it runs the same differential configuration. My question to you is I just want to put LSD in it do I still have to worry about the backlash? As I am not taking out the pinion just the Carrier. Please advice Thanks

Great video at first i was going to going to have a shop do my gears but this video series gives me the confidence to do it on my own. Video quality and editing is top notch.

Thank you. If you follow the take aways of this video and use a proper set up bearing, it's not that bad. Good luck.

Great videos. I'd recommend against using an impact on new bearings

@ronlemon640 3 жыл бұрын

Would you have been ok if you made sure to get the same pinion bearing that you took off to have a setup bearing? Great info man. I really enjoy your videos you really explain what n why you're doing what you are doing. Thanks n keep it up Todd

you can also use a ratech crush sleeve eliminator kit make setting the pinion preload a breeze, and yukons differential shims come with a lot of smaller shims had to get the yukon kit to get mine in spec easier. also the koyos are a higher torque bearing then the timken both will work but the koyo is the one they use in the gt500 differentials koyo std4183 is the bearing number for anyone wanting to know

Hey Eric, great content, quick question would the diff cover you used fit on my 04 marquis? It’s a 8.8 as well

Welcome to hoodralic press. This bearing is extremely dangerous and could attack at any time. We must deal with it.

hi to you, great video with lots of explanations. Today I am replacing my differential but I cannot read the setting value on the pinion. How to get your opinion, a photo where? thank youps : (my car is a 1995 Cherokee Jeep)

@wookielaney5971 8 жыл бұрын

when i did the setups on the differentials for john deere we had to immobilize the pinion to get a good backlash on the diff.

I have changed the pinion seal without a new crush sleeve or special tools. Since bearing wear is going to make the pinion bearings very slightly looser with wear. just take off the drive flange(part that holds drive shaft cups). pull out seal. replace seal put flange back on. have a clean pinion threads and knut threads. Put some high strength lock tite on and tighten knut till you get the bearing drag for used bearings. Actually you can feel that well enough. All went well and over 150k later was still good. yes you can do some things without special tools. Other than leaking pinion seal, and outside axel bearings. I have never had a differential fail in over half a million miles.

I would say, if you are trying to get by cheap. get a good junkyard rear end and just use it.

The crush sleeve's purpose is so that you can change a seal and have a torque on the nut without affecting bearing preload.

Im doing mine now and rebuilt the whole thing and changed from a 3.73 gear to a 5.13 and started off with the shims that was in it and it felt to little of back lash but it was right at 8 and did the paint test and looked good so did i hit the rear end lotto or what.

@halleffect1 7 жыл бұрын

i shimmed the rear axle in my friends F-150, it was making lots of noise. he had super high backlash, I was surprised the gears weren't destroyed. BTW- Eric, I can see you put a lot of effort in this video. Great job and thank you for your dedication.
