Wheel bearing replacement

[Mike1919]

Ok. So I'm planning to replace my front end components and after 220k it might need it. When I was shopping for rotors it looks like they come with cups already pressed in the rotor. Is it OK to mix and match the cones and cups in a wheel bearings. For example, can I use a Timken wheel bearing cone and whatever cup comes in the rotor or will it cause me problems later on? Thanks

Background: the reason I ask is because I'm around heavy duty trucks all day and I know you cant can't mix cups and cones in the wheel bearings due to different hardnes of both metals causing uneven wear.

I think the issue is when you mix old cups with new bearings and vice versa, as long as they're both new I don't think you'll have an issue. I've done it before and I'm about to do it again and I've yet to have a wheel fall off.

Truthfully I do not know.

I think what you call a cup is what I call a race. I've been wrong lots of times so maybe again.

I have used the race that was already pressed into the new rotor and replaced with new bearing just so I would not have to remove and replace a new part.

I hope you get a positive answer because now I am questioning my laziness.

I've not had a problem but maybe I was just lucky.

EDIT: I see that I am not the only one. Good

The only problem I could see is if one of the new parts is low quality.

i believe your right and it is called a race. I just want to confirm that the race is pressed into the rotor right?

I believe the race is pressed into the rotor. Tho newer stuff is unfamiliar.

Those preinstalled races are chinese garbage (yes, even the ones in premium rotors such as Raybestos Advanced Grade or whatever they're called).

No harm can come from getting rid of those china things and using the race that is supplied with (and matched to) your bearing (it takes only a couple minutes to R&R a race even with just a hammer & punch). However the potential for harm from mixing parts of unknown quality is quite high (and is very likely a reason why we see the abnormally high rate of bearing failures on these frontends we do).

Can we all agree that Timken is a good bearing?

Timken good

The first bearing job I did used Timken bearings...not too many out there with other names but they lasted me 10 years or more and I didn't even have to repack them after all that time...not even sure what the maintenance routine is on front bearings...

Perfection, thanks guys
