Ok, so i noticed some slight grinding noise the other day. Kinda like a slight growl. I hear it most at low speeds (15 to 30 mph), if i hear it and put any pressure on the brakes it goes away. While turning and accelerating it goes away.

I thought a sticking caliper, so i checked the temp after a drive see if one was heating up more than others. The front is water than the back, but in florida this time of the year everything outside is hot. All four rotor seem to have the same amount of wear. If it is a rotor how would you isolate it?

Then i was reading about the bearing hub assembly. I jacked the truck up tonight and spin the wheel, no noise and no slob indicating a bad bearing. On the passengers side i got a slight clicking, but thats not the sound i am hearing

So, does anybody have any ideas before i take it to the dealership. I have a trip coming up in two weeks and i drive 100 miles a day, so i will have to take there soon if i can't figure it out.

Any and all input welcome, Thanks

What do you mean by "slight clicking". If you jack up the front end. Grab the wheel at the top and bottom and give it a rock. If the clicking results in any play, then you have bad wheel bearings.

Tire are the #1 thing however that will cause a growl. I have a set of tires that have a terrible growl. I swap tires from summer to winter. The growl of my poorly worn tires are loud.

I jacked the truck up and rocked the wheel no slop (sorry typo last in first post). The clicking was while spinning the wheel, was more when rocking it back and forth not a click every revolution.

When driving the truck the sound of the tire drowns out the grinding sound after about 30mph. There is a slight bit of cupping on the left front, i thought from a poor alignment after a lift 500 miles ago. I had it realigned Saturday and noticed this noise Sunday. my wife was in the truck, so i didn't have the radio on when i was creeping thru lower parking lot and first heard it.

I got a hub bearing assembly and going to try that Friday night. I did the swerve and try and see which bearing it is, but it seems to stop either way I turn.

I am hoping its the side with the cupping on the tire. and that is the cause. I will keep this updated.

The hub bearing behaves differently when there is no load on it. By jacking the front end up, you remove the load from the bearing so it might not be noticeable using that method. Looks like you are on the right track with the new bearing.

Yeah, Zero Six I hope that what it is. Its just making it hard to tell what side is bad. I see it says in the sidebar you are in Miltown. Is that referring to Milton, florida? I live in pensacola.

Yeah it is a hard place to leave. Moved down about seven years ago and haven't looked back.

On another note i got a 32mm axel socket (hope thats right), some fresh pry bars, and freeze off. I am going to swap out the hub assembly tomorrow after work.

Update
Well I swapped out the drivers side hub assembly. It went pretty painless, but wasn't the culprit. The wah wah wah is still there, but maybe not as bad at 15 to 20 mph is the most notable. I think because of road noise. Is it possible that after a leveling kit the positive camber wore both bearings out? The truck is 4WD and has 75k on it. I have no clunking sound so guessing not CV's yet? Warped rotor but would think i could feel that when stopping.

Dealership said nothing is wrong. They said they took a stethoscope type tool and assured the bearing is good. They said it was tire noise from the cupping. On my way home tho i heard the noise, touch the brake and it goes away. If its tire noise it should still make the sound with the tires rotating. So now i am back to thinking sticky caliper, but if i swerve or turn the sound goes away(that leans toward bearings). So I am pretty clueless.

Were they driving the truck when they diagnosed the noise? Did you take it to Sandy Sansing?

Yeah, Sandy Sansing thats where i bought it. They said the tech put 4 miles on the truck listening for the noise. They said if i left it till Monday they could have the shop Foreman look at it, but its my daily i need to get to work Monday. I think I am going to call Monday and see if the shop foreman will go for a ride with me. I told the guy today we could go for a ride and i can get it to make the noise, but he was confident in his tech that nothing was wrong. He said it might be cause of your lift kit, but 2" spacers and 1.5" blocks are not going to make a grinding sound sorry.

Any resolution on this? I have a grinding wah wah wah noise, but mine happens at hwy speads and banking left. I suspect hub assembly. Curious if you figured this out?

Yeah I took it back to the dealer and the shop manager rode with me. He said my brakes were dry and needed to be cleaned and lubed. I have never heard of this, but for $49.99 i said why not. I have put about 1500 miles on since and not a sound.

If your sound goes away consistently by turning to the left i would check the hub. The sound my truck was making would actually go away when i turned either way. The Hub was pretty easy to change out, I think it took me about a hour and I had it done and cleaned up.

Thx. My sound is activated by the turn. Think that's what you meant. But it has not gotten worse at all over time. I am thinking of just swapping out both front hubs to be on safe side. Napa apparently has a "second saturday" sale where top line hubs are $170 apiece and middle line hubs for $120 apiece.
