NOTE! If rebuilding a used unit, make sure that the side gears and pinion gears go back in the same locations they came from. I usually mark with a small grinder, one of the teeth on the left hand side gear and the pinion gear on the side with the cross shaft bolt. And if you always do it this way then you will always be placing your gears in the same spot even if it sits in the garage for two years before you put it back together. Thanks
Hi, when removing c clips to replace leaking axle seals the spider gear thrust washers fell out. Is there any way to get these back in without too much work It is the original 12 bolt 3:73 posi, and everything is still in place...the car is on jack stands, 69 Camaro.
I think that this the style I have in my tundra and it stinks. Its pretty much just open now... don’t know that I want to rebuild it just to have it wear out again. My go with the tru track gear drive option.
what is the deal with the factory 4 series carrier like the eaton one posted, 5 of the discs with the ears and 4 regular with the teeth that slide on gear, put the god damn thing together and it wont turn no matter how thin the shimming is, went from .009 up to .044 same shit, falls apart trying to get little spider gears in
Tom I'm tired of trying to find a skilled person to work with so I'm just going to throw this out there and ask do you have the time to rebuild my differential? It's a 78 positrac with 355 gears. Please advise Thanks
Unfortunately Tom, my pops, passed away in January. We are still running the business and selling parts so let us know if you need anything. Thanks, Lesli
Tom's Differentials very sorry to hear this, was thumbing through his videos for a 9”: I’ve found his videos very useful, must have been a pretty cool guy and seemed a great teacher willing to share his knowledge. Condolences.
your going to have to tap them out , the raised part is not that thick so shouldn't be that bad , butt you will need to replace the axles , so you have the correct end play
+toms diffs got u .i did not want to damage the inner bore though when tapping. end play was .140 and .135 and its crunchy with little fluid found in the case .crunchy but gears are good 79 vette I hope GM additive ll take care of the sound. joints look good bearings replaced.ll clean metals and put new axles thanks

You got a nice shop Sir.
6:48-7:30 thats the most important thing to grasp from this video.....Thanks Tom!
best video on youtube about this... thank you. for making this.
of course , used to do them all the time , the o.d. of the standard 12 bolt shims need to be trimmed down a bit to be able to use them..
Ok and thanks for you response!
I have what looks like tge same posi unit 1960 chevy C10 looking for parts.
Never mind, just introduced my carrier to my sledge hammer.
How about a rolling torque spec with a needle style wrench? Gr8 vid otherwise thanks, must watch for any home wrencher adding this unit !
its best to order on the phone so i can get the usage app.. yes we assemble them..thanks tom..
it sure does ! that way you have less clutch wear..tom..
Super video tom!
I have one question, do you have to spin the unit if you use carbon fiber Clutch to?

Hey tom can i apply the same principles to the eaton lsd carrier that uses the s spring instead of the 2 plate and 4 springs
hey tom where do i get the assortment of shims to do this tune prosses. i have a 8.5 86 cutlass 442 rear 373 gears
great job!! does this tuning apply to a gm limited slip with z spring? thank you

fairly simple thing to do if you have patience..tom..
Good video sir! Is there anyway to tune up a Detriot tru traxx posi unit with the worm gears in it??
Hey, I want to put a posi in my truck. Would this be a fairly simple thing to do? I am mechanically inclined.
Jo-eL
What happened to the preload springs? Does your technique eliminate them?

Tom's Differentials so sorry to hear that. What a great guy. I bought many parts from him over the years for my axle rebuild business. Gonna miss him.

hi tom I can't get my axles out they got mushroomed any tricks to grind them out?
your going to have to tap them out , the raised part is not that thick so shouldn't be that bad , butt you will need to replace the axles , so you have the correct end play
+toms diffs got u .i did not want to damage the inner bore though when tapping. end play was .140 and .135 and its crunchy with little fluid found in the case .crunchy but gears are good 79 vette I hope GM additive ll take care of the sound. joints look good bearings replaced.ll clean metals and put new axles thanks
