Intermittent LF vibration

[Seabass]

Every so often i'll hit a bump with the left front and i'll feel a vibration like a bad hub bearing, and then i'll go over another bump and the noise/vibration will go away. The truck has new locking hubs and i even drove it without the hubs on the truck. Any ideas?

seized axle u-joint?

 

[Seabass]

the axle doesn't turn when it's "unlocked"

the axle doesn't turn when it's "unlocked"

unless it has a seized u-joint

 

[Seabass]

that's not a simptom for my issue

 

[POWER-STRUCK]

ok!

 

[Seabass]

i think it's the needle bearing in the hub bearing

:whs: that's what mine would do when the needle bearing failed
