Ford 8.8" Differential Complete Tear Down
Автокөліктер мен көлік құралдары
All of the information in this video will also apply to the GM 12 bolt as well as other differentials of this type.
The #FairmontProject needed a new differential. The stock 7.5" wasn't going to cut it. So I got an 8.8" out of an '86 Mustang. The Mustang rear end had Traction-lock, but I'm not reusing that carrier. Since I'm upgrading to 31 spline axles, I needed to upgrade it anyway.
Perhaps at some point I'll go back and do a rebuild of the stock traction-lock differential, but since I was upgrading anyway, it really wasn't necessary.
***I show how to make a 'set up' bearing in this video. I learned the hard way that this may not always work out. If you are going to use a set up bearing, I recommend purchasing 2 new pinion head bearings and using one for set up. You can purchase set up bearings separately, but they are way more expensive than just getting a second bearing.

i`ve watched a lot of car programs on tv and your channel is the first one that shows work being done and tools actually being used not a load of mechanics moaning to each other about the job an timeline. Great channel i`m clueless when it comes to cars but find your video great to watch the engine swap videos got me started on your channel

Thank you!
Thank you for this series. It was the difference between selling my truck to pull a part, & putting it back on the road. I'd have never tried to rebuild a differential without videos like these.
I'm in the process of rebuilding a Ford 8.8 to put under my Mustang. I've watched this video probably 2-3x already and I'm sure I will again before the jobs done. Very helpful for a novice mechanic.
Your excitement for this project is palpable, and it makes the videos fun to watch. Your videos feel more upbeat and humorous of late. Keep it up!
Definitely one of the best videos I’ve seen on the teardown process. I enjoy these videos, Eric.
Sir you are so detailed with your work along with good energy, your videos are very inspiring. Keep up the great videos Eric.
*SOOO NICE*- to see you back at your Shop, and back to work on Oliver! Eagerly awaiting more of this series. THANK YOU, ERIC.
Great video Eric, nice too see you so happy working on something again. Looking forward to the rest of the fairmont vids.
Changing my 2000 ford ranger 4x4 to an FX4. 31 spline from a 28 spline with spartan lockers. Eric you are definitely an excellent teacher thank you.
Eric, you did a great job on showing all the different tools a person needs to work on the differential and you hit on all the important points of marking the parts so it all goes back together correctly also thanks for showing your work instead of fast fording to the end to save time .... Stay safe and stay dirty !!!!!!
I watched this nearly a year ago to get to the part about removing the axles. Now I'm back to rebuild the insides. Great content.
Im a jeep guy and this is a very popular swap for XJ/YJ/TJ jeeps. This is the best junkyard 8.8 tear down i have seen yet. way to go ETCG!
Great and enjoyable disassembly as always. Looking forward for the next parts.
Eric, Thank you I've got a 94 Explorer(8.8) with a leaking axle seal that i'll be replacing in the morning. This video was right on time.
OOOOOOH! The Fairmont project is starting to get REEEEEALLY GOOD! Chompin' at the bit again... but enjoying the journey as well. THANKS!
In the beginning you called it a posi-trac. I was losing my mind trying not to correct you, so I kept watching. You specified the Trac-loc (l/s) and a weight lifted off my shoulders. Thank you for being knowledgable.
Thanks Eric for putting the Ford 8.8 videos up. A couple years ago I acquired a '93 F150 base model with the tried/true combo of the 300 six, M5OD and 8.8 rear with 3.55 gear set. The previous owner drove it with a totally destroyed rear u-joint. After I went through the truck I noticed that on short runs at highway speed the diff was getting abnormally hot up around the pinion bearing(s). No noise or other symptoms. I'm suspecting that bad u joint trashed at least the outer pinion bearing. Thanks to your helpful videos on teardown and setup (in addition to a factory service manual), I feel confident that I can do a rebuild.
Thank you Eric. Your videos are always very informative.
Thanks for the heads up on those bearing caps!
Oh man this was a great video! I don't know much about differential rebuilding so I definitely learned something. Looking forward to the subsequent videos!
This is awesome! Thanks for the teardown Eric!
i like watching these videos. they teach me something everyday.
You are a born teacher. Superb detail. Thank you!
Watched you last night and today I pulled my very first diff apart. Keys were missing but I got really lucky and when I pulled the cover off the pin retainer screw was right there and I didn't have to remove the drive shaft. I was just going for the carrier to swap my ring gear onto but you gave us everything
He's chill like that, definitely earned a follow off chillness
great tips eric, i always learn something watching your videos
Finally Fairmont videos :D The long awaited chapter begins :D
It's amazing to see how happy he is in these videos. Probably because he's building his baby finally.
I really enjoyed this video Eric. I learned a few things about differentials that I didn't know, thanks. Thanks for sharing Roy

Glad to hear it. Thanks for your comment.
Excellent content, thank you for uploading.
I use a paint roller. hammer the handle arm flat. spray brake cleaner in tube and push debris to center. clean it out. makes for a great, clean tube assy. Be sure to pack outer wheel bearings with axle grease due to it taking a while to lube. If not you'll burn up outer axle bearing. Great video AS ALWAYS ERIC!!
Nice attention to detail,it really made your video stand out.
Most comprehensive video I've found thank you
Just watched this for the third time, getting ready for my tear down on my ‘86 Mustang 5.0. Wish me luck!
Very informative, well laid out video. Thanks very much!
Thank you Eric. Your teaching is very clear.and I do diy.
I'm really looking forward to the rest of these 8.8 videos. I have two 8.8 axles that need to be rebuilt. These videos will help me decide if I should take them to the axle shop to get them done or if I should invest in the tools to do them myself.
Good video - learned quite a bit!!
Eric, you're like the Bob Ross of auto mechanics: your canvas is your workshop and your medium is cars.

I love the smell of Gear oil. I miss going to school to study this. I loved the power train classes. I can't wait to see how you do what you want.
Eric you are just like me. "I'm going to hang on to these because one day down the road I might need a part from in here." it just happens that you hang onto it for 6 months finally throw it away and one week later you have a reason to need it. never ever fails

Love Eric's video have been subbed and watched for years. Sometimes I forget to thumbs-up them when I watch them but when he made the tractor beam sound and said "amber vision" i scrambled for the thumbs up. Even though without it Eric would have gotten the thumbs up.
Thank you again Eric this is a great vid for what my ford 8.8 will do to my chevy s10.
Great video as usual,you're not a pack rat, your smart, i do the same thing, i have a cardboard box where i have tons of Mustang parts, springs, screws,levers, brackets, you name it,even light bulbs,those parts have come in handy more than once specially now these cars and their family like your Fairmont are getting scarce.
great video eric, definitely a nice break from these pull a part videos, lol. keep up the good work man!
hey Eric the car guy. I'm 17 years old and from Indiana. I plan to be like you 1 day. I go to college this year's for automotive. you have helped me soo much!!
Another great video! Like the rest of us, you certainly are happier working on a project that has nothing to do with work. I really enjoyed this one...
I replaced an axle on a 2000 E150 - sans limited slip! - purty much like this. The air hammer/chisel is pretty much the tool 'o' the century! Nice vid!
Great work Eric.
you were positively giddy in this video. nice to see :)
I like the way you work on that.
Have assisted in building a 12 bolt and a couple 9 inch rears. So interesting to see an 8.8. Didn't know they shared anything with a 12 bolt. Looking forward to the rest of this series. Setting rear ends up was probably the most time consuming/precision thing have ever done on cars, as if not done right, esp on a performance car, it will cost you. Heh wish youtube would have been around then, would have helped alot.
That was amazing! I owe you for all this knowledge sharing, sir!

Hey Eric congrats on the 800k subs!!!
Very informative video Eric. Thanks.
Wish you were near me. I would work for you for free just so I could learn what you know. You are a great mentor and father figure. Keep up the good work Eric.
always the best videos eric!! thanks
That was very informative thanks 👍
This humor of yours, I really love it!
thanks! I've been waiting forever for this video
OMG OMG OMG! I have never hit play so fast. I'm actually early for an ETCG video for once! The last time I came this fast, my girlfriend left me. Roll on the rest of the Fairmont videos!

Hahaha. I just want them All. NOWWW!
new Fairmont video, my Friday just got better.
A quick and easy way to remove the e-brake cables from backing plates is to slide a boxed end wrench over the expanded tangs, I think 1/2'' wrench for most. It compresses them all at the same time and the cable pulls right out. Beats fighting them with a screw driver.
Another very informative video, thanks
I am really liking the direction of this build mostly because I love old Ford cars and trucks, also I like a good sleeper. I'll bet it's going to be fun on the street with 5 speed
awesome video!
Good old "80-90 Stink"! I agree I hate that smell too! Just wanted you to know that I learned a couple of things. I learned how to use my brake spring tool! I've done my fair share of drum brake jobs too. I haven't see the offset box end wrenches like you used. Thanks!
good video and very easy to understand,thanks!
You're a good mechanic.
nice work well explained fun to watch 10/10
NICE WORK
Thanks , for the great video schooling.
Great video
Thank you buddy you’re awesome🤘🤘🤘🤘🤘 couldn’t have done it with out you
Looks to me like you might have done that a few times there Eric. Actually I have never had to pull a rear end apart so this was very informative in case i even wanted to do a rear end swap. Thanks for the video
Damn. Not sure how but you're always working on exactly what I am when I'm doing it. I had my Outback that's when I found and subbed your channel and learned everything I needed for that. Now I have a Ford with an 8.8 that needs rebuilt look today and here you are rebuilding one. Hahaha
Man! EricTheCarGuy, I throughly enjoy your content. This video is very helpful I just bout a 2004 grand marquis and this diff is very similar except I think mine doesn’t have traction lock
You seem just a bit giddy doing this. Honestly, I've seen some of this before, but this was a very comprehensive and well-shot video. Thank you.
Great video Eric that air hammer sure saved you some sweat and blue language there.
Yay, back to normal content!
Hi, just replaced all the bearings in my Lincoln Town Car that uses the same differential. Your video was great advice so I knew what was coming and what to look out for. It went smooth but I did it with the differential in the car and only jack stands, no lift. It was no fun but doable. Had to improvise regarding the preload on the pinion bearings since I have no lb/in or cNm torque measurement tool and they are about 300$+ overhere. I worked with a thin and light wooden bar and weights and did some math. Also, no press but heating the bearing to 200F in water and freezing the pinion gear and carrier in the freezer was enough to let the bearings glide on with no effort. Physics and math can sometimes replace expensive tools! The differential works absolutely fine now and I was abel to do it on a weekend. Best regards from Germany.
The best video in youtube, thanks
Thanks Eric! You the man!
Wooooo! Awesome video bro!
I did similar work 12 years ago on my dif. while hanging in the car. the top bushings were a pain in the butt to get out even with the air hammer.
A few years ago my outer pinion bearing in my 01 Durango's rear axle, it howled all the way home. I helped my dad replace the pinion and carrier bearings at home ourselves, because a shop would have charged about 700 to do it, , but a good quality set of bearings only cost $100. Its a Chrysler 9.25 with 3.55:1 gears. The pinion was a little smaller than that, but it was still fairly large and very heavy.
Thanks for another great video! On getting the smell of dif oil out of your skin, I use 50/50 pine sol/water then dish soap. Seems to do a pretty good job!
I see a future Pull-A-Part video coming. LOL. JK Eric. I'm one of the few that liked those videos...
Good video. Thanks.
Hey Eric,I wanted to say I use a box end wrench to take them type of parking brake cables off. I just slide the one that fits over it down, and it pulls the tabs in and you can just slide the cable off, that is if your gong to reuse them.
awesome. cant wait to see the paint video and the assembly. I hope you are going with a Detroit trutrack :)
Someone may have mentioned this before, but the damage on the crush sleeve was from the fragment pieces you found inside the case. You could see them near the sleeve location when the pinion bearing races were being hammered out. Sorry if this was a repeat comment. Love to watch you work, Eric... hate to have to do the same thing myself as a follow up.
Can't wait for more fairmont videos.
this time on eric the car guy, how to do a pinon reach around on fords rear end
I've used a 9/16 or 1/2 inch boxed end wrench to compress the tabs on the Parking brake cable retainer. That works quickly. Slide the wrench over the cable and it compresses the tabs.
The secret is not in the screwdriver, the secret is fitting the appropriate sized ring spanner over it to compress the clips. Best way to do it.
I had 2 fairmonts and 1 mercury zepher these are sexy cars!
Love Taps Lol Kudos on marking the caps i do same thing Cheers
