Removing and Installing The New Eaton TrueTrac Differential

[@thatsmycar8150]

Nice vid, considering the eaton or yukon. Bearing caps are on backwards, arrows point towards the wheels.

[@AllThingsBoost]

Yeah, this was my first time messing with a diff. I've since gone back in, put a new gear set in, properly shimmed it and got my backlash and pattern proper, and made sure the caps were facing right lol. But it is quiet as can be now.

@@AllThingsBoost Awesome, this isn't a straightforward job.

[@adamcresswell2064]

Do you still have the other spacer by chance ?

[@Twobarpsi]

Good job on the R and R!!

9:15 They sent you a 10 mm socket?

[@fishtail3052]

Man can i pick ur ear?, you seem to know alot and i just had a shop install mine on my 02 gt, i pulled the axel out and brought it to the shop i had them powder coat and install one of these and 4:10 gears with yukon 31 spine axel shafts, i get it back to the car bolt it all up nd wen i put the my dual caliber brake setup i noticed that on the passenger side the rotors are perfectly in-between the brake calipers but on the driver side the rotors are so close they are almost rubber my calibers somethings not right, i havent even broken it in yet, Advice?

[@AllThingsBoost]

Interesting. So I had a weird issue with my first set of axles, some fords (f150, explorer, a few others) have an ABS ring between the ring gear and differential. It's about 1/4, but that means if you have an 8.8 (like in my car) that doesn't have an ABS ring in the diff, then it will be offset to one side. For mine I couldn't even install my first set because it was offset enough I couldn't get the c clip on, and the other side looked okay but probably stuck out a hair. Had to order a different set of axles and the second set was setup for my my style diff and 8.8 and fit fine. I'm betting that could be what you're experiencing, maybe the shop clearanced an axle tube to make it "fit" but obviously it's not right

[@Twobarpsi]

Bearing cup! The part with the rollers is the cone.

[@AllThingsBoost]

Thank you! Haha It was killin me!

[@Twobarpsi]

@@AllThingsBoost test drive? Did it work? Also good job on keeping the backlash the same, at 0.010" 👍

[@AllThingsBoost]

It definitely feels better, the noises the diff was causing are gone, but the solid lower control arms still transmit quite a bit of noises to the cabin. I thing I might go for a bushing design down the road if the rear seat delete and some sound deadening material dont quiet the noise down a bit.

@@AllThingsBoost what was the 10mm socket in the parts bag for ? Did that come from Eaton?

[@hotroddude6551]

Its call a Race. Bearing Race. Not a cup

[@mr171009]

Great vid, I’m looking to do the same, is this the Eaton Detroit tru-trac? And do you have the #?

[@AllThingsBoost]

I don't have the part number, but yes it is the one you listed. I have an updated video called fixing my gear whine, or something to that effect that goes into detail on installing the proper shims and setting backlash and all that. Much more info than this first attempt

[@lynnboynton5640]

This guy says this was so much fun.

[@israelaldaba46]

I was go 40m n it went to a clcomplete stop it still start but no go

[@tjoyce81]

Using the bearing race to press on the bearing can cause a flat spot on the bearing rollers - thus a possibility of causing noise and vibration that you will never find. That is a bad practice. Also - you installed the bearing cap up side down. The arrows on the cap always point to the wheel - this too, can cause a vibration... Not sure how precise you like to be - but any vibration in the drive line is not good... Just an observation, but all and all good video...

[@AllThingsBoost]

Thanks, I'm pretty inexperienced when it comes to a lot of this, so I appreciate the pointers. I will probably revisit this as I'm learning more and make some adjustments and do new bearings for piece of mind. Thanks

​@AllThingsBoost do you have the other spacer by chance still

[@BoostaholicRacing]

Good stuff brotha!! 🤘🏼🤘🏼🤘🏼

[@jackiel9054]

Send it! great vid

[@blackriflex39]

im pretty much trying to do the same thing . how do you like the eaton diff? im boosted 450 to the wheels and my old factory diff is failing so i plan to upgrade while i daily drive this car i do like to visit the track both drag and autox as often as i can... in your oppinion what are the pros and cons to this diff? great video i noticed the nc plates im from Shelby

[@AllThingsBoost]

I actually really like it. My only complaint is I should have swapped out the crush washer on the pinion gear for shims, because it still whines pretty good, when you launch it slowly crushes that washer putting itself out of spec. I've had a bunch of 1.6 60ft launches and one 1.5 and its held very well, so all and all big fan of the diff.

[@vandettabuilds6641]

Very good video. I’m going to put one of theses in my truck. Did the locker come with the bearings

[@AllThingsBoost]

Nope, had to buy a bearing set separately.

[@charlierosene1117]

what was the 10 mm socket in the parts bag from or for?

[@AllThingsBoost]

I found it hiding under the battery tray in my truck, completely unrelated to this install. Forgot it was in there.

[@jasonkennedy2348]

Could we see one of these installed in an F150?

[@AllThingsBoost]

Should be the same process. I dont own an f150, so I can't show an install on one....

[@moejr14]

What’s the best oil to put in the truetrac?

[@AllThingsBoost]

Go onto Eaton's website and find out for sure, but I believe it was a GL-4 80w90 standard oil. Non synthetic, no friction modifier

[@moejr14]

@@AllThingsBoost thank you. I had one install and it’s popping in turns really bad and found online/forums it may be the diff oil that’s causingbit

[@seanhernandez1466]

Is this a 8.8 rear end?

[@AllThingsBoost]

Yes. I have an updated video on this as well setting the lash and doing a few updates that I didnt do at this time.

[@slaughtertwo]

What weight fluid did you end up with?

[@AllThingsBoost]

80w90 gl5 rated. Went with valvoline. Eaton says no synthetics, so just the standard stuff.

[@StillNoPickles69]

It wouldn’t be 10.1 lmao it would like .0101

Yep
