Re: 2001 Ford Expedition - 4 Wheel Drive Isues?
The wheel bearing (hub assembly) I've bought have all been 'factory sealed' meaning no grease joint. However, I've had good luck with mine. Most last 60K or more without issue. I abuse my Durango and the left front wore out 20K before the right front one did. It sees a lot of towing during the summer months and the rears are still good! When the fronts went, they didn't wobble much and barely made any noise except at low speeds and doing tight turns (at lock). I'd love to get 300K on a set. Perhaps my next vehicle will.
