knuckle started smoking up

[konarider1993]

right after the knuckle rebuild  bearings froze up??

[Slolyfe]

Pull it apart. That should tell you. Grease everything?

[mudaddict]

I agree tear it back down and inspect if it was smoking more then likely something was not greased properly.

I didnt put as much grease in this knuckle because i ran out. Think i could just pump some in?

No. Did you pack the bearings?

[konarider1993]

Yeah

[Slolyfe]

Yeah

I would pull it apart and find the problem. Once something is smoking I'm pretty sure its too late.

[konarider1993]

darn i really dont wanna do that again

[Slolyfe]

Just think of it as practice for the trail. How much driving did you do on it? 2 or 4 wd? How much smoke? Jack it up and shake the tire back and forth. Is the hub hot when it smokes?

[OOPS]

Which bearings froze up, trunnion or wheel bearings?

Were you wheeling (in 4 WD) when it started smoking?

Did you pack the Birfields full?

Did you pack the trunnion bearings?

Did you pack the wheel bearings and set them up right?

Here is a link to the section of the FSM for setting up the whole frontend. Read it.

I did quite a bit of driving on it. It started smoking when i was on the road in 2wd at a stoplight and i could see it coming over the hood, then drove less than a mile home, and it quit smoking.

[nisota]

Enough smoked to see it coming over the hood? Holy crap! when you tear it down post pics of smoked knuckle please.

[OOPS]

Sounds to me that your wheel bearings were to tight or something is wrong with your brakes causing them to drag.

[junya92toy]

No way its the knuckle bearings, they just turn a little when you turn the wheel.
Its more then likely you over tightened the wheel bearing nuts.

[Cheesemaker]

Best advice in a situation like that, is to pull over and look and feel where the issue is.  IE; is the hub hot?  Rotor hot?  Caliper hot?  Upper/lower bearings hot?  That way you could diagnose the issue right away, instead of trying to guess after you get home.   

[jrock]

You sure it the knuckle? Maybe something got onto your exhaust or burnt off your rotor?

[konarider1993]

I did get new calipers, pads, and didnt resurface rotors and they had oil on them but i dont know. I took it on a couple hour road trip after the knuckle rebuild and had no issues previous to this. I hope its just oil burning off rotors

ok, that leads me to think somebody else did the job and you were either not there or liquored up and didnt know.

you either packed the bearings with grease or you didnt.   

there is no physical way that the trunion bearings smoked at all.  it has to be the wheel bearings or you were running down the interstate with your hubs locked and burned the birfield up.

the rotors had oil on them??  where the hell did you learn to run with oil on your rotors??

it is very easy to get the wheel bearings too tight  and after a short drive they could very easily get so hot that they smoked that much.  in that case you need new bearings and races.

true true i think it was oil on rotors i didnt resurface them. I got a bigger problem now though.
