loud hum/grind from pass front end...NOT THE WHEEL HUB

2004 psd 150k

so i have this very loud hummig/grinding coming from my front pass side.... the noise starts at 20-60mpg(tire/road noise over powers it after that).

The wheel hub is a brand new Motorcraft oem part # maching wheel hub assembly and still the noise is there.

Swapped tires around to even see if that was the problem.

Took out the locking hubs and still the noise comes in, and even in 4wd the noise is still there.

The diff case is full with diff oil and it looks good and no smell.

Any ideas here guys? I'm admitting defeat here.

I'm in the Littlerock area if anyone is local and want to see in person the problem here.

EXTRA INFO: the front pass axial as ALOT of play in it like there is suppost to be a seal or something in there right behind the hub, i can literally move it over a inch any way up/down side/side.

interesting

if it does it with the actual locking hubs removed

I would start with trying to turn the front drive shaft by hand to dble check

it's disengaged I would also try and turn each axleshaft by hand

that would eliminate the whole transfer case concern

and most of the front end possibilities

i notice the axial play when i was replacing the hub, i took off the driver side and saw it had no play so i know theres a problem there but with it being my DD i hade no choice but to save it for another day.

i can turn both axials no problem by hand, seem smooth and trouble free.....also when in the passanger seat you can feel the vibrations from whatever it is in your feet.

i'll check tranfercase fluid level tom to make sure but me and 10+ buddies all agree its pass side its coming from.

wheel also spins with no issues at all.

like i said i truely give up at this point and accepting any help or ideas.

Welcome to guzzle's 4x4 Needle Bearing Maintenance Web Page

yours is like this mine is different but if the needle bearing is new and the axle stubshaft are fine it may just be a axle u joint issue

lol

the axle-shaft is a little more involved than the hub because you need to pull the knuckle seal and reset it with a special tool to depth

I think the needle bearing is replaceable but I think it also came with your new hub

mine uses a complete different sealed bearing that is replaceable

FYI on the needle bearing

Quote:
With the hub off, we expose what this entire exercise has been about, the needle bearings, yep those non-serviceable, non-existent bearings that the dealerships apparently have no knowledge of. Hopefully you can see on this photo that there is a small amount of lubrication remaining on these bearings but they do need servicing.
If your needle bearing looks worn, you should replace it with a new bearing (Ford-C6TZ-3123A NAPA-B2110
)
