01 f350 with noise in front

[jbb2001]

i have a 01 that makes a noise like you are driving over rumble strips not all the time ,it did it with the auto huds and now i put new warn hubs on it and it does the same thing if i lock my hubs it dont do it,

What ended up being the problem? Just found a couple more similar threads but no answers.

My 2000 F350 with manual hubs had a similar problem on the drivers side, turned out to be the wheel bearing assembly. Had to get the whole assembly replaced because they are not serviceable. I remember reading in FOUR Wheeler about an aftermarket serviceable replacement. Guess the front end on the big Fords having bearing issues is pretty typical. Same kind of sound that you described, a rumble through the floor that comes and goes.
Good Luck

Typical of Needle Bearings being bad, cheap easy fix and is actually a serviceable part in the front hub.

exact same problem i just ran into..it just started the last week or so.. rarely did it now it does it alot...

I checked everything possible and only found the left lower balljoint had failed..

Replaced both with MOOG and went for a drive...still there..

im going to remove my hubs tonight..go for a drive see if the noise goes away..it does it most the time after hitting a bump..at a slower speed..im confused on this one..i hope its not the hub..but i do have a spare one in the garage if it is..

** update**

went for a drive, both hubs unlocked, rumble strips lived..

locked both hubs..noise was gone..

inspected, found drivers hub seized in the lock poistion, turned to auto but stayed in lock, beat in on the concrete cause it pissed me off and it went "pop" and now works fine..

no noises yet..

noises are back..gay ***..apparently the passengers side wheel bearing is acting up..i have a spare swapping tomorrow

It's the needle bearings in the wheel bearing assembly. Been there done that got the T shirt. $30 in parts for both sides.
