Front wheel hub bearings

Does anyone know if the front wheel hub bearings are serviceable? If so how do you access them.

I had to have one replaced on my previous d-max, I think I had to buy a whole new bearing.

they are not serviceable...they are a sealed unit and run about 350 a piece depending on where you get them.

Same thing on my 02 about a week ago. Left front, its non-servicable I have a buddy that works at the dealer and he sold it to me at his cost it was like $239 list was $369 I think. My dad found one made by timken on the internet for like $156. I cant remember the name of the place Ill ask him. It was like a Autozone or O'Reilys but online. I had to leave the next moring to go 1300 miles so I had to have the one at the dealer. Its easy to change but my trucks 2wd. It might take a little more on a 4wd with the front axle. Pull the wheel, caliper and bracket as an asembly, slip off rotor, pull four bolts and its off. 100 ft lbs on the four bolts to put it back in I think is what they were and your done.

I have a 2006 1500 CC Z71and have less than 30k miles and I have replaced the right front at 19k and the left front at 28k. This was very frustrating. All Covered under warranty, but that is why I got a new truck. I realize these are not as heavy duty as the HDs.
