Why do wheel hubs fail?

**Brammer** · 09-09-2015

I was thinking about it today, why are the wheel hubs on Grand Prixs notorious for failing? Is it a design flaw? Poorly made bearings? Lack of decent grease?

i think that's the point....you shut up while you try to figure out what it means.

On this topic i may have a rear one going. Was does it sound like when it starts to go? Can it be a very gradual thing? I have a noise from LR and could be just road noise but never noticed it before so....

I've had them making a howling noise, a warbling woo woo woo based on speed and I've also had a grinding when they go really bad!

Personally, my thought is they are under engineered for the application. Most GM FWD cars of the period had the issue.

as a weird addition..

the other day someone said to me that the cheap hubs they buy the usually give them a couple whacks with the hammer before installing to make sure the bearings are fully seated. i've never heard this before, but it'd be a good reason as to why a lot of hubs fail immediately or shortly after installation. how much truth there is in this statement i have no idea because i've literally never heard it before and i've never done that either.
