I started having this problem with only the passenger side front wheel not sure what is wrong with it. Even replaced and put a new Hub Assembly on it that was not cheap and very hard to find. I also notice that my truck was the early model so it also has 1989 Ranger parts on it this again made a major problem. I have been buying bearing after bearing thinking the bearings could of been just sh*t but the same time I replaced the driver front but haven't had a problem with it at all. So very confused why this even started. Please give me some input to fix this problem or a way that I can seek to fix it.
