Hey all:

I have an 04 DC 4x4 tundra that is making what sounds like a bad wheel bearing noise, or chopped tires, that can be heard from 10-50 mph. it seems to be most noticeable around 45mph. It does almost go away when I turn RIGHT, which got me thinking it was the passenger side wheel bearing. There is some vibrations that accompany the noise, which can be felt in the floor. The tires are fairly new, maybe 10k on them. I decided to drive on it some hoping it would get a little worse and diagnosing it would become easier, but it started getting to me, so I replaced the front passenger wheel bearing, and its still there. When I had the front pass wheel off the ground during diagnosis, I could hear/feel roughness when I turned the tire. So now I'm thinking it's at the front differential.

I'm looking for any suggestions on how I can pinpoint the problem, as I'm at a loss.

Thank you all in advance for the brainstorming efforts...

 

Check the CV joints before you dig into the diff....

 

Did you ever figure out this problem? I have an '02 Sequoia that is doing the exact same thing. I replaced the right wheel bearing, then the left. Neither fixed the problem. I would be real interested to see what the deal was with your Tundra ... I may have the same issue.
Thanks!

 

my issue ended up being a wheel bearing. i did one side and then had to do the other as i guessed wrong. i do hear a slight noise again, and im hoping its just tires. carrier bearing should be checked. good luck to you.

 

Thanks for the insight ... I appreciate it!

 

Update ... mine was the LR wheel bearing. Got it up on a lift and listened with a stethoscope. The LR bearing was just a little bit more noisy than the RR ...
