Wheel bearing seals, backwards?

OK, so sticking to tradition (of me putting things on/in/together backwards/reversed/thewrong#@@#$way, that is) I am pretty sure I pounded the wheel bearing seal in my hub the wrong way.

Should the back of the seal (away from the bearing) be flat and flush, or should it have the gap along the circumference of it seal with the steel spring-like ring inside of it. Making any sense to anyone here???

The pics are of the seal that I potentially pounded in backwards, and the way I think it should be on top of it (it has the flush, flat side towards the bearing, which I think is wrong), and the two different sides of the seal.

Sorry for the bad news but I'm almost sure that you put that in backwards. I've only done this on SA vehicles, but don't think that should matter. Hopefully, others will chime in.

awesome, rather find out now than in a grease spewing f-bomb flying bad day.

thanx thanx thanx

and thanx for warning frodin, but im pretty sure im gonna replace it neway, it got a little dinged up on the way in.
Anyone have any home rem's for pressing these seals in without the proper tools? I just tried to whack it it with a 2x4 laid flat over top of it to suck up some of the impact and ended up dinging it up a little bit.

If you have to run down to the parts store for a new one, don't forget to stop and get some food for your cats.

Hey, i need to do my front brakes, so is there a kit with all the seals?

Also what is good to replace while doing so? I was hoping to just turn the rotors, but are new bearings necessary?

You should just need to buy two wheel bearing seals, one for each side. Bearings are only necessary if they are trashed. If the bearings currently on it have been adjusted correctly up to this point, chances are that they are fine.

I've had some luck with the end caps from plastic drain pipe, they're cheap, come in different sizes and are soft enough not to damage the seals.

I just went to napa, got the seals and bearing for both sides, had em in stock.
Don't think they're a super reputable brand name or nething, but oh well. Up here in the land of igloos and outhouses im just pumped I found parts at all without waiting 2 weeks.

I think the bearings are fine, but what do i know?

As far as the seals, i was at toyota and the guy didn't know what i was talking about. so it is just the two seals? are they the inner or outer seals? I was told there was both

The inner bearing has the seal, and the outer bearing (closest to the wheel) has a race on it already, so it does not require the seal.

It's weird, sometimes you'll get a guy at the dealership in the parts dept who seems to know everything, and then the next day the guy doesn't know what an axle nut is... Newb hire, i guess.

I just used a rubber mallet and was careful to make sure the seal was going in evenly.

There are three seals on each side. The one pictured is the inner hub seal. There is also an outer hub seal that bolts to the spindle, and a seal on the inside of the spindle that seals the CV shaft.

My kustom seal driver...

you can also pick up seal driver kits at any auto store but those cost money
