Let me start off by saying I have been a long time lurker of these forums, but have not signed up until today.
To get down to business. I noticed that my 2009 Tacoma (4cycl 4x4 access cab) is making a rubbing/humming noise from the passenger side of the truck. The truck has 71k, and I bought it new with 6 miles on it. Let me start off with saying I thought the noise could be cupped tires, and since they were relatively old , the first thing I did was have the tires replaced (I bought mastcraft hsx's $165.00/ea). Much to my surprise when I left town fair tire, the rubbing/humming was still present. I then tried diagnose the issue a little more. The noise is present in 2wd, and 4wd. The noise stops when I turn right, and offload the weight of the right side. From this I decided that it had to be the passenger side wheel bearing. So yesterday (from the help of this site..thank you!), I removed the hub/bearing had a new one pressed (moog) in. With the wheel bearing replaced, I got it all buttoned up and took for a test drive. The noise is still there! So I spent last night doing a little more research, and thought that it had to be the passenger side cv axle. So once again today I spent the day in the garage, swapped the cv axle (w/ a napa reman), and buttoned it up again. Took it for a ride, and the noise is still there!
The noise almost sounds like tire noise (if I had really aggressive tires). I really at a loss of what else it could be? Has anyone experienced anything like this before? Could a warped rotor or worn pads do this?
Thanks in advance for any input given!
