wheel bearing going out?, Causes? Options

[easternpiro1]

Hi all, while I was driving I notice that im getting a sort of knocking sound under hard acceleration and as i cruised heard what appeared to be that "wooo wooo" sound. I JUST replaced my wheel bearings with a factory toyota wheel bearing kit.


My question is: what would cause a new wheel bearing to go bad? Im 99% certain I put it back correctly and that the person that pressed it in was reputable.

If you're on lowering springs that could be the issue. When I was on Tein S-tech's I had to replace three bearings in a short period of time.

I don't think this is correct. How would lowering springs affect your bearing in any way?

x2 on the bad hub. Also, the method of install. If you're having it done at a shop, or doing it yourself and they aren't using a press, and simply hammering them in, this can also cause damage to the bearing, and premature wear.

I took everything off at a pal's house and had the bearing pressed in at a shop. i should have saved pics of what the old hubs looked like!

You sure your tires are not rubbing against the plastic under fender?

Im posiitve. i guess whats more concerning is that it makes more of a knocking noise under hard acceleration. my wheel dosent seem to have any give in it (indicating bearing is bad) its only been about 2 months since I replaced it.
