I have a high pitched whine coming from my front end, I replaced the wheel bearing 3 years ago and it did this for a while. I engaged 4 high and drove slowly and it went away. this time nothing cures it. I installed Warn premium hubs a few years ago without the spindle nut conversion, could I have killed the wheel bearings? it has made the same noise with both sets of hubs however. I have ordered the spindle nut kit and will install it and whatever else it needs.
