I have a 03 fx4 4.0 auto.
When I put my truck in 4 hi, it seems like the front right tire is binding.
It seems to pull and jerk right. Makes a low pitch wrrrrrr sound.
I have no problems what-so-ever in 2wd.
I replaced the wheel bearing about 5,000 miles ago, I don't think i used the 4wd since then.
