Bad parts out of the box w/ pictures

Here's a few pictures of bad front wheel hubs. These are National brand sealed front hubs, made in Korea. National is owned by Federal Mogul and both companies used to make good quality parts. I installed these hubs and was bringing the van around to another bay to do an oil change. It made it about 200 feet. New hubs will be coming right from GM.

It's a 2004 Chevy 1500 Express Van. The original hubs went bad, so we bought an aftermarket set of National hubs. First and last time for the National's, we've always just used the factory GM hubs.
 
Both hubs !? Wonder how many of them they screwed up?
JD dealer was here yesterday to put new parts on my brand new planter, only thing was the replacement parts were no better than what I already had !
 
About 3 years ago, my mom needed the front wheel bearings replaced in her '96 Taurus. I got two National branded front wheel bearings for it from a local auto parts store. One was American made and had a nice machined finish to the whole assembly. The other was Korean made and the finish was terrible. As I took both of them out of the box and set them side-by-side on the parts counter, you could tell that the Korean made part had not been assembled correctly. I showed it to the parts man and had him order me another one. After getting the replacement bearing the next day, I installed both of them in her car. A month later, the Korean one failed. I got a replacement under warranty, but that did not pay for the labor that it took to replace it.
 
If you think the government motors ones will be any better or not made in korea or china you are nuts.
 
Just had to replace daughter's rear bearings & hubs on her 2004 KIA Optima, 84,000 miles.KIA wanted $490 for parts only. Auto Zone had 2 choices, Duralast for $99 & Timken for $136...same 1 yr. warranty. I went for Timken because I did not want any problems & certainly didn't want any Korean junk from dealer. Timkens came in & guess what..."Made in Korea"...can't win!!!
 
Do you REALLY think GM makes their own unit bearing hubs, and in the USA to boot?

Yeah, RIGHT!

Thats what I was thinking. GM uses whomever is the lowest bidder for their parts. Low bidder = overseas.
 

That is the very reason I do my very best not to
any thing out of the USA, and yes I kow it hard not to but like I said I do my very best not to:
JR.FRYE
 
I think you put the wrong part on. 4wd front hubs on a 2 wheel drive. The cv axle and nut would have held those bearings together and they would have been fine. autozone give out wrong parts all the time. I would be giving the parts store you bought them from a ear full for giving you the wrong parts. There is a diffrence between hubs for a 2wd and 4wd
 
The new GM parts came in Isuzu boxes. Doesn't say where they're made at, though, Japan I'm guessing.
 
I rebuilt a transmision in a John Deere a few days ago. All parts came from Deere. Bearings and seals made in China.So much for dealer parts being any better than anyone elses.Don't forget our global economy.
 
I went through that with GM when I got a set of hubs for a 2wd 3500. They sent over a 2wd hub and a 4wd hub, I called to say they sent the wrong hub, they did some research and GM superceded all 2wd hubs to the 4wd hub. I've had the 4wd hubs on that 2wd truck for over 2 years and 50,000 miles and they've never fallen apart.
 
HOW would the 4X4 unit hubs be sealed in a 2WD application without the axle shaft inserted in them... the inner lip seal on (at least the GM truck style) seals to a shoulder on the CV axle shaft.

Without the axle shaft in place the inner bearing would be exposed to dirt and water AND the hub would be prone to falling apart without the axle shaft to hold it together.

Unless there's an inner grease cap that fell off with the bearing (which a 2WD hub WOULD have), I'm gonna go with cjd12000 and say you mucked up and installed 4X4 hubs on a 2WD!!!!!

(I HOPE I'm wrong 'cause if you did that, you'll NEVER "live it down"!)

Better double check on that tonner, too, just to be SURE the hubs that are on there are OK!
 
4wd hubs will have a splined hole through the center for the CV shaft. If a 4wd unit bearing is run without the CV shaft or at least the stub passing through the hub and torqued to spec the hub [b:fa63d30684][i:fa63d30684]will[/i:fa63d30684][/b:fa63d30684] fall apart. The 4wd hub is lightly pressed together but the stub shaft is what actually holds it together.
 
Is it just me or does something not look right here? How could 2 hubs fall apart 200 feet from the shop. Was this not put together correctly? Looking at the pictures it just looks like something is put together wrong.
 
Yes, LOL. My latest two GM parts purchases, both in the blue / white AC Delco boxes, a clutch kit and a water pump are marked "Made in China" Both were good quality and have run for 6 months and two years with no problems.

My last two true "POS" new parts, defective to the point of being unusable, were both marked made in USA. One was a $1200 combine part.
 
You got that right. I've found GM OEM sheet metal and aftermarket offshore sheet metal with identical manufacturing flaws.

Also, about 15 years ago there was a story going around that GM OEM replacement sheet metal were parts that had been rejected off the assembly line.

someone didn't install the axle through it....hmmmmmmmm

Its a 2wd van, as it has coils springs up front. 4wd vehicle would have had torsion bars up front.
 

I was thinking the same thang,,, thumbs up,,, BTW BTDT on the GM verses aftermarket hubs,,, on cars I use only GM hubs but never had a problem with aftermarket truck hubs,,, I do like the fact that GM uses bearings with no name stamped on their differential bearings on late model pick ups,,, it makes for a nice ticket replacing them....
 
Express vans came in awd and 2wd so I am going to say with certianity they gave you the wrong parts. Counter person probably just assumed they would be the same and i bet they never asked you if it was awd or 2wd cause at least on that van there is a diffrence in pn. Izuzu is as american as gm and chevy
 
Based on the information you posted,
you should have gotten part number 515054 (or 515053 which it replaces).

an awd version would be 515036.

my computer shows 03-06(later on 2wd) have same parts information.
so do the pickups. Maybe partsguy heard chevy 1500 and went into automatic mode and looked up 4wd pickup, as it's the most common chevrolet model for parts inquiries. No excuse for his/her slack, but it might explain why it happened.

ps hope you get your money back, and if the wrong parts were sold, the store can make it right for you.
 
i pulled a 515054 off the shelf and you cannot put your finger or a shaft through it. the center of the wheelside of the bearing is cast plugged off, and there is a dust cap on the inner side where your bearings fell out of.

I would venture to say that these pictures are staged. they are almost mirror images, the way the bearings are laying. also how does the hubs maintain even spacing in the wheels with the bearings out?
