How Can I tell if my front wheel bearing is bad on a 1992 ford explorer and how do i change it?

It is on the front passenger side and i have aftermarket lockin hubs put on a year ago. There seems to be a rubbing noise coming from that side and when i lock in the four wheel drive it gets worse any ideas?How Can I tell if my front wheel bearing is bad on a 1992 ford explorer and how do i change it?Sometimes the manual locking hubs can make noise. My warns were making more of a clicking sound and I look the lock ring off the outside of the outer axle and this took care of the noise. That ring is not really necessary because, for there to be a problem the axle would have to slide out a full 6 inches to disengage the hub, if this happens you have something far worse to worry about. A bearing noise will be a rough or %26quot;roar%26quot; noise at approx. 30mph and up. It may seem to go away at higher speeds, but it is usually masked by wind and tire noise.How Can I tell if my front wheel bearing is bad on a 1992 ford explorer and how do i change it?it would be a good idea to take your hub apart, see how much dirt and debree is inside, when you lock the hub in it moves internaly, and may be grinding up dirt.How Can I tell if my front wheel bearing is bad on a 1992 ford explorer and how do i change it?to check a wheel beering jack the vehicle up so the tire is off the ground put a jack stand under vehicle for safety grab the tire one hand on top one hand on the bottom rock the tire if you have play in the wheel then you need to check out wheel bearing(don't rock tire side to side).Take apart hub inspect the hub assembly also inspect the axle
