F250 front end noise revisited

Any other suggestions? I took both front hubs off,took the 8 nuts off in behind and pulled the needle bearings. Everything was tight and packed full of clean blue wheel bearing grease. I repacked it with more new wheel bearing grease and put it back together. Took it up the road half a mile,but it's raining so all I could hear was the splash on the wet road and the noise of the cold diesel engine,so I don't know if I helped anything. I can't imagine that I did since nothing appeared to be wrong.

The tires only have about 6000 miles on them,don't have any uneven wear.
 
Didnt see the original post.. What kind of noise. I have 250 gas 2000 that has noise from front. Kinda hard to explain.. whooshing sound but I figured it to be tire noise. I do have some aggressive tires.
 
If the noise goes away when you turn back and forth while driving it's probably a wheel bearing. Did you look at the bearing really good? As in whipe all the grease off. Is the front diff getting worn.
 
I took everything out and cleaned it up,repacked it. It makes the noise with the hubs unlocked. Only thing worn is the ball joints. I know that now anyway.
 
from your description last night, it sure sounds like a wheel bearing. Clean them good and turn them by hand, look at the rollers really good for signs of pitting, it could be the inner races are pitted and the only way you will see is to cut the cage and remove the rollers, I have seen this in pinion and diff bearings before, you know the sound, but initially they look ok, cut them apart and the cause is obvious. The side that gets quiet when it is unloaded by swerving is the side I would look at first.
 
By chance did you check the axle shaft u joints? Like ASE said earlier in his post the lock outs could be not fully disengaging and turning the shafts. I've had one side of the joint freeze up so bad when it got in the right spot you couldn't steer the truck.
 
Ya,they're OK. I turned the wheels around with it on the jacks. Even reached in and turned the axles. It's probably been longer than I think,but I had the axles replaced once because the u-joints went bad. From the look of the grease I think Jeff must have either repacked all the bearings or replaced them at that time.
 
I really can't tell Jon. Last winter when the wife's truck blew the engine and one of the boys got in with me to go drag it home,he complained of a noise under his feet on the passenger side. I think the noise he was complaining about was 28 year old suspension though. If there was a better side,I think that was the better side as far as everything being tight and right.
 
I realize that this is way out in left field, but sometimes noise will "travel" in that it sounds like it is coming fro one place,when actually it is coming from somewhere else. Since you have pretty well checked out the front end, could it possibly be coming from the rear axle bearings, or differential? Just a thought.
 
Let me go out on a limb and suggest something else... could be a side bearing in the diff shelling itself out. In that case, the noise would probably be there all the time, but worse in a turn when one axle wants to walk in or out slightly. Also, the noise/vibration might telescope down the axle and sound or feel like it was in the wheel. Just a thought.
 
I know you can't run beside it
. So put it up on jack stands block it up real good and don't get wraped up in any thing put the stethoscope on axle housing at the ends and at the diff. That's the way I do it at work only I have a lift so I can walk under the vehicle. Good luck
 
As Shadetree and others said below: had '80 Blazer with slight "whoosh" sound straight ahead, got to be "rumble" in turns. Swore it was in front, checked out bearings/hubs/brakes/tires over several weeks with no joy. Friend at Chevvy dealer drove it for 10 minutes-said REAR differential side carrier bearing. Pulled it down, replaced both bearings, and noise vanished completely. New one on me, drove it for several more years with no problems.
