Why do wheel hubs fail?

[Brammer]

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?

ill tell it like my dad used to tell me when i asked why this or that.


because Y is a crooked letter and cant be straightened.....wtf that means i may never know lol

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.

Probably because the GM engineers never paid much attention to the weight in the front of the GP's and adjusted the suspension accordingly... Lolz
