vehicle: 1998 ford explorer sport, 5spd, 2wd problem: i have a noise from the front end of the vehicle. it is sounds like a grinding-ish growling type of sound when: i have a slight growling noise that is there when im driving straight ahead. when i turn left or right, the growling/grinding noise gets much worse. what ive done:i figured, "well duh, its the wheel bearings, time to replace them". so i bought brand new timken bearings (2 inners and 2 outers with races) new cotter pins, and valvoline "ford" wheel bearing grease. removed old bearings and races, but the old bearings looked just fine, no scoring no blueing, no nothing. i said, "eh, maybe i just cant see it with my eyes". put the news ones in, followed fords wheel bearing torquing procedure, but instead of using an in/lb wrench which i dont have access too (only 2 snap-on lb/ft wrenches) i just used my feeling and made sure there wasnt any play but the wheels spun freely with no noises. the symptoms CONTINUED. i remember having the tires replaced way back at walmart all the way around, and when i drove it home on turns i noticed some noise. not a lot though (i think, i dont quite remember) and certainly not as much as it is now, or i would of taken it back right away. when the car is jacked up, there is no play when rotating the wheels, or any growling, grinding, binding. could tires cause a noise like this?
