Drive Train Axles Bearings problem
1999 Ford Ranger 6 cyl Four Wheel Drive Manual 120000 miles
I had to replace the wheel bearings this summer (came with the whole hub assembly). Before I did that, my four wheel drive worked fine. I bought my wheel bearings from Ford, so they should be a perfect fit. Now, with winter snow, I turn the 4x4 on and my front wheels don't move. I've lifted the truck up and engaged four wheel, the front drive shaft and axles spin, but not the wheels. So, I took the wheels off to see what was up. The inner gear/cog of the bearing was spinning.
Now, I am not positive on how the hubs work, but from looking at it (maybe I'm wrong and someone can correct me), but their are two gears in the wheel bearing. The outer one spins with the wheel itself. The inner one is controlled by the axles, driveshaft, and transfer case. The purpose of the hub, is to relay the motion of the inner gear/cog and axle to the outer gear, and turn the wheel.
Now based on my observations, I'm assuming there must be something wrong with my automatic hubs, but they seem fine and my 4x4 worked fine before the new hub assembly was installed. I really don't want to go buy two hubs at $160 a piece or try to find one in a junkyard.
I've read from other sources about o-rings that keep contamination out. If contamination occurs, 4x4 could be lost. But I've also read that the hub Ford used starting 1994 doesn't have this o-ring. I don't know the validity of these sources and I haven't gotten to check the hub for an o-ring either, but it's a thought.
