Looks like I need to replace driver's side front wheel bearing hub due to bearing starting to fail. I have a rotational rumble that is directly related to speed and is getting worse. It occurs in both 2WD and 4WD. Things done so far: new tires w/ alignment, locking hub maintenance, new brakes - rotors, calipers, pads and hoses, new shocks, front axle turns freely and u-joints look good. I think this all started when caliper froze up on that side or it could just be the mileage (281K). Rock Auto seems to have the best prices. Any recommendations as to Timken or Motorcraft? About $100 difference in price.
I'm probably missing something, why does the hub have to be replaced if the bearings are bad? That sucks.
The hub bearing on a 4x4 is a pressed together, sealed unit.
I work as the milling department head of a fully tooled cnc machine shop...
We do not have the capability to rebuild a hub unit at my shop.
Not much of a chance for the layman to accomplish such a feat in his home garage...
I ordered the Timkens with a 3yr warranty from autozone for about $150 each. It was the only place I could find that offered 3 years. Amazon and others say only 1 year. The motorcraft ones were too rich for my blood at about $260 IIRC.
I picked up my Timken hubs / bearings at the local AutoZone and they were pretty reasonably priced. Much cheaper than the Motorcraft and a better quality, at least in my experience.
Jim, if you buy locally you have the opportunity to manually turn the hubs to check for too tight torque from the factory. I bought two Timken bearings. The first one had a "ratcheting" feel to it when turned by hand, indicating too tight a factory torque. The second one the outer stub support needle bearing had been pressed to tightly into the hub causing the needle bearings to lay slightly sideways and preventing the needle bearings from spinning. So I asked the auto parts store to bring out two more for inspection. Both of them were ok and still work after 15K miles.
