Inner race turns in the hub on my k20
Put it here for more exposure. Repacking the front bearings they had plenty of grease but I’m going to Tennessee next week . Bearings all clean look pristine but when wiping out the old grease the inner race turns in the hub . Not sure if I should continue or get new cups and cones

Re: Inner race turns in the hub on my k20
That should be a press fit. Can you slide the race out of the hub? Given the tight tolerances on bearings, I'd think that the hub is damaged.

Re: Inner race turns in the hub on my k20
the race is much harder material than the hub, if it spins you need a new hub. i have in the past used a center punch to score the hub so the race would be tight- but only in an emergency situation until i could get a new hub.

Re: Inner race turns in the hub on my k20
Yep exactly correct. I’d replace that hub and races at a minimum asap.

Re: Inner race turns in the hub on my k20
Popped out the race it’s been overheated. I have the hubs coming and I just ordered the cones and cups from Rockauto

Re: Inner race turns in the hub on my k20
Good call, that’s probably been that way for a minute. Luckily you can still find the 44/10 bolt hubs fairly cheap/easily. It’s nice when you can get them assembled with the rotor like that. My front Dana 60 is expensive to replace hubs on and they are a little tougher to find.

Re: Inner race turns in the hub on my k20
Well the hubs will be here tomorrow morning I’m going to try and get the cones and cups at Napa tomorrow. The online order site says that I can order tonight and pick up tomorrow. But I’ll just go to the store early and see if I can get them . I’ve had the order now and pick up tomorrow lie before .

Re: Inner race turns in the hub on my k20
If the cups in the new hub are the same brand, they should match the cones. I've seen where one can buy the cones only. I don't know if there is any savings with that, beyond the time of having to pound out the "old" ones and pound in the new ones. Working as a piece-work mechanic in the past, it would have been less labor.

Re: Inner race turns in the hub on my k20
Locktite makes a green compound that works well for this application. I’ve had to use it for knuckle bearing races. I always knurl the edges of whatever the race is going into, apply green compound, then press the race in.

Re: Inner race turns in the hub on my k20
Not a fan of chemical bonds overheat it and it turns to goo . Granted the high temp is rated to 450 degrees but I’m not trusting it . I’d rather replace than patch .

Re: Inner race turns in the hub on my k20
Glad you are getting back together, you definitely made the right call replacing the hub. As for the newer race in the old hub I wouldn’t put it past someone in the past to have just dropped a new race into a wore out hub. Lots can happen In 35-40 years.

Re: Inner race turns in the hub on my k20
I’m the third owner . Both prior owners were very anal about the truck . I have every receipt and work invoice and every piece of the original paperwork including the bill of sale . Guy even kept the recall notices and the envelopes they came in . First owner was a mechanic second owner is a member here .

Re: Inner race turns in the hub on my k20
All done this morning . I think this had something to do with the shudder vibration I’ve been dealing with on the truck . Took it up to 75 mph no vibrations was super smooth
