started hearing some really bad noises when I am turning right. I think its the wheel hub falling apart. Anyone replaced one? How much do they cost and whats a good place to get one?

 

4X4?
Should be under $200 or so with ABS sensors, less if only RWAL.
Rock auto or quad 4X4 has them.
Make sure it's not you're Universal joint binding before you shell out the money for the hub.

Quad only had 2500/3500 hubs

 

I've done 3 front hubs in mine, countless others in my other vehicles. I got mine for my Ram for around 120-150 I think, with 1 year warranty. Not really that big of a job, the hardest part will probably be getting it separated from the knuckle, they seize in there good sometimes. And a little tip: change the ujoint while you're in there if you think it might need it now or soon, it'll save you the hassle of taking it apart later.

 

thanks guys, yeah I think I will change out the u-joint also.

 

could be the hub or could be the axle u-joint on 4wd.
timken 4wd hub for 1500 is about $180. 2wd is cheaper.
if its the u-joint, napa has a greasable Precision brand for about $29/ea that's very beefy and strong.
there's a good tech thread on pavementsucks for each.

 

i type too slow...

if you pull the axle out for u-joint replacement, be very gently and use lots of grease on the axle when reinserting it, or you'll damage the seals buried deep within innermost parts of the axle tubes. you'll also push ****loads of dirt into the differential housing...
