Sound in the front end. Possible wheel bearing.

I have a 06 Pre runner with 136K. I have a vibration and a humming sound coming from the front of the truck. The sound that it makes sounds very similar to knobby tires. The sound happens when the truck is moving regardless of wether Im giving it gas or not. I have lifted the truck off the ground to check for any play in the wheels or weird sounds thinking it may be the wheel bearings but there is none. Does anyone have any ideas of what it could be. How else do can i check to see if the bearings are going bad?

Just went thru this myself. If I had to do it over again and I had the time I'd get the hub assembly from bama and replace them myself.

 

Thanks for the info. Im going to check out those assemblies today. How long did you drive with the humming sound before you had them replaced?

 

Im about to go do that right now Ill let you know what I find. Is there anything else that you know of that it could be so i can check it while I have everything of?

 

most likely your bearing...does it go away when driving through a corner in either direction?

 

With mine, the sound changed when turned, going around a sharp corner. I'd just do both sides, from what I've read it's extremely common for the 2nd gen and most I've read had to be replaced before 100k so yours are overdue.

I drove mine at least 1000 miles on the bad bearings, I was on my way down to md from ma when I noticed it. It's really amazing how quiet it is when the bearings are good and fixed.

 

Had both fronts done last week after a summer of listening to them whine.
Mine started out low sound on the drivers front just when I turned right, turning left made it go away.
Then it was a steady groan on drivers side except when turning left.
Eventually it was steady no matter what, and the pass side started when it was turned right.

Now it's all quite.

 

I got the tires and brakes off. Should there be any sounds when im turning the bearing?

 

Any ideas?

 

Well at least I can pretty much say that they are shot. makes me feel better about dropping $550 to replace both. i think im going to go with the Bama hub assembly.

 

No it doesn't go away or get louder in the corners

 

Have you ever had to replace wheel bearings? If so did you do it your self or take it to a mechanic?

 

Did you get the ones from Bama?

 

I replaced both of mine on my 4x4 In the last month, which I assume is harder than the prerunner since the axle goes through the hub. If you have the tools, it should not be too difficult. Ask a friend to help if you need, but basically you will unbolt the 4 bolts holding the hub on and swap it with the new one.

I got mine from https://www.tacomaworld.com/threads...-complete-save-custom-built-available.288055/
