Did the u-joints really lack factory lube? Probably never.

All the grease would be distributed within the bearing cups due to centrifugal forces. There's your air-purge.

 

The joint is not fully greased if there is air in the joint. Spinning it would not remove the air and add grease.

 

I'll have you know that I have a Toyota Engineering degree from Tacoma World University, taught by @NunyaBizness himself. So this is true

 

Grease is heavier than air. Physics dictates that the grease will move to the furthest point from the rotation axis. That would be the bearing cup where its needed.

 

Yeah...about that... Im being investigated and all degrees given by myself have been suspended.

 

Well shit...

 

That still doesn't fill all cavities with grease.

 

You forgot a crucial detail in your analysis - feelings. We are, after all, in an era of feelings superseding facts.

That said, I feel that you and this thread are fantastic ♡

 

I got a feeling after page 4 some people are gonna need some grease for all the butt hurt this thread is causing

 

OK. You win. You want grease just sitting in the cross of your u-joints where it does nothing. All you need is grease in the bearing cup. Sure, occasionally there may be a Spicer u-joint manufactured short on that sweet grease. I would worry about something else personally. But you do you my friend.

 

The thing I need is more beer.

 

*Diet Coke

 

*Kombucha

 

The bearings in the caps are greased, the cross assembly is dry, the first time you grease the u-joint you're filling the channels in the cross assembly

 

*D̶i̶e̶t̶ Coke

 

Shit, tomorrow is Friday.

Guess I will log off for the next 30hrs

 

Blasphemy

 

This can't possibly be true...

 

If I'm gonna give up on a 5 year steak of not drinking soda, it's gonna be Dr Pepper

 

We are in the 3rd gen forums... wake up... its always friday here... why else would @jberry813 be deleting it all the time?
