Show me where a Blazer complete hub is $72.

I know he needs a whole assembly, I was just reffering to them as a bearing.
Its been pretty well established that you have to change the hub assembly.

I think the Wheel Bearings Direct ebay store is the same guys that I bought mine from.

Of course youre not going to find anything from AC Delco for less than a small fortune.

Those "hubs" are still American made by an oem, and come with a warranty.

This is my first post here, so please, be gentle with me.

I am looking at replacing both my front hub bearings on my 2000 GMC Jimmy (4-door/2-wheel drive). I found this http://www.shop.com/GMC_S_15_Jimmy_W...19646-p!.shtml and was wondering if it is the correct part? I may not buy that specific item, but moreso am curious if that's the right item I need. I have seen some on the internet that describe the part as having the ABS sensor, and some say nothing about it. I'm just worried I am going to order the part, tear apart my truck, and find out I forgot to order "this cable" or "that bolt".

Any information you folks in-the-know could provide would be greatly appreciated.

(some gee-whiz info: My bearings have been humming since the spring of 2006. I have since driven from Alb, New Mexico to Biloxi MS, and have put around 15K on the truck since the hum began. It has gotten progressivley worse, but has not failed yet. I'm at a hair over 120K total on the truck today)

The link you posted is for the bearing/hub assemblies for 4WD. Yours being 2WD are much cheaper and simpler to replace. Remove the wheel and unbolt the caliper, do not disconnect the hydraulic line. Remove the hub cover and cotter pin. Remove the spindle nut, washer, and outer bearing. Remove the rotor and remove the inner bearing and seal. Drive out the old bearing cups from the rotor and install the new cups. Pack the new bearings with grease and reassemble. Total parts cost for both sides should be about $60.00 or less.

I appreciate the response. I am a bit confused, but I may have the reason why. I was informed by a small automotive repair shop that they were sealed bearings, and also had them checked out at another service station during a seperate issue. Both places had told me they were sealed bearings. From what I gather, the 2wd is not supposed to have this type? If I do in fact have sealed bearings, I believe the reason may be due to a large vehicle accident I had back in 2005. The front end of my truck was struck from the side while I was sitting still. The other vehicle was a Ford F-350, traveling at approximately 65-70mph. The damage was substantial, but the insurance company wouldn't label it as "totaled", so it ended up being repaired. I am thinking the repair shop may have swapped in a sealed set. Is it possible/feasable? Anyhow, I plan on placing my Jimmy on a jack tomorrow, removing the wheel and taking some pictures to post here. Thank you for your time.

4WD has 2 sets of sealed ball bearings in each hub assembly. They are serviced by replacing the entire hub assembly.

2WD has 2 sets of tapered roller bearings in each hub. Each set of bearings, and the hubs, can all be serviced individually.

The two types of hubs and bearings are not interchangeable.

(The website in post #47 has a misprint, should say "4WD".)

Yes, those are the correct ones. I would recommend buying the hubs locally, that way if you have problems you can go trade them in and be up and going the same day. When purchased online, your vehicle will be out of service for a long time if you have to send them back under warranty.
