Re: 76 K10 hubs shaky top to bottom

Don't forget to check or replace the axle shaft u-joints too while you're that far in too. Get some Spicer 5-760x's

Re: 76 K10 hubs shaky top to bottom

Definitely will. Thanks for that. My goal is to have more than what I need by my side, replacing everything that makes sense to replace, and then return anything that was not used. But I've never worked on these types of parts so I'm trying to figure out what is needed.

Re: 76 K10 hubs shaky top to bottom

Is there a seal at the end of the axel? If so, mine must need to be replaced.

Re: 76 K10 hubs shaky top to bottom

That inner axle shaft seal is on the inside of the axle, behind the ring gear and carrier. You can remove the carrier to replace them and reinstall without setting gears as long as any shims that are present are put back in the same exact location they were removed from. May as well buy/make a tube scraper if you replace those seals to get all the grime out.

Thanks for the info. To replace the seal that is likely causing this leak, would I have to pull the differential gear out? Is this the right part on LMC's website? In the other picture, is this where the seal is? Thanks for your help on this.

Yep unfortunately that’s the one. They can be a pain to get out and install. I have an install tool I made with 1/2” all thread and 1/2” fender washers that just barely fits in the ID of the seal land. As said above put the exact shims in the exact position they came from. You’ll have to pull the spindle to get the axle shafts out in order to replace the seals. And yes there is an inner bearing, inner race, and an outer bearing and outer race. Along with the inner spindle needle bearing that supports the axle shaft.

Good idea. Do you think this is the right u-joint? LMC shows the axle u-joint for 1973-87 4wd, 1/2 ton. Mine is a Dana 44 8F

I don't bother with LMC for these parts. RockAuto has them all, and cheaper for better parts;
Its the same ujoint used on both Dana 44's and 10 bolts, 73-87 1/2 ton and 3/4 tons.
Here is the axle shaft ujoint https://www.rockauto.com/en/moreinfo...t=2392&jsn=614

Spindle bearing kit- https://www.rockauto.com/en/moreinfo...t=1672&jsn=637

Axle shaft seals- that go in the housing; https://www.rockauto.com/en/moreinfo...t=1852&jsn=624

Here is a pdf of the factory service manual if you don't have one, same info thats in the '76 supplement manual.
