Forgot to clean them first though... Is that a problem? With the layer of grease?

Spray them down with brake cleaner and see if they taste metallic or like the protective coating.

Replaced the rotor, bearings and pads on the passenger side. Easy peasy. But on the driver's side... One of the lug nuts won't come off. Ordered a nut extraction set. Hopefully that'll arrive soon so I'll be able to do the driver's side as well.

I just realized I might have used the wrong grease to pack the bearings. I used ordinary bearing grease with a dropping point of 375F. I'm guessing that's too low. I'm going to get special automotive wheel bearing grease before I start on the driver's side.

If I decide to repack the wheel bearings on the passenger side (and I'm hoping to get some advice if it's really necessary), I'll have to remove the rotor again. I was wondering, will I destroy the inner seal if I do? Will I need to get a new seal? And what's the best way to clean the bearings and remove the old grease?

The grease I always use specifically says 'wheel bearings' on the can or tube, and is rated to 400 F, so you might be fine, what did you use?

I usually use this or Lucas Red 'n Tacky



If you end up re-doing it, a bearing packer and a grease gun would flush out the old grease.

Ball Bearing Grease

Looking up the codes (DIN 51502, KP 2 K-30), the specifications of this grease are:

K: Greases for Bearings
P: EP additive
2: NLGI 2 grade viscosity
K: Highest operating temp 120*C (248*F)
-30: Lowest operating temp -30*C (-22*F)

So yeah, that's not good at all. 😕

Will I ruin the (new) seal if I take the rotor off? There's only one place I found in the Netherlands that has them, and they are between $25 - $30 a piece (including shipping). Same seal, same brand is only $2 in the US... $8 with shipping.

Most likely yes, seal will be damaged in the process.

The same brand has special Wheel Bearing Grease for automative use.

But when I compare the specs of this grease with the grease I used, the only difference is the max operating temperature which is 140*C (284*F) instead of 120*C (248*F). That's not really a huge difference...

Remove the spindle nut.
Remove the washer and outer bearing.
Reinstall nut.
Slide rotor off enough to feel inner bearing hit nut.
Push back on a little then slam the rotor back towards you to knock out seal and rear bearing which will remain hanging on the spindle.
Seal should be fine but inspect.

Why is it so ******* hard to get anything in my country? Spent 5 hours today driving from store to store trying to get some wheel bearing grease. Not a single place carries it. Even car parts stores only have "General Purpose Grease" or "Ball Bearing Grease" which are really only suitable for skateboards, bicycles, roller skates... And when I tell them a temperature rating of 250F max isn't really suitable for using as a wheel bearing grease in cars, they look at me as if they see water burning...

You would think that these things would require some type of bearing grease

Bit late to the game here, and I hate to say it, but make sure you get one that says DISC BRAKE wheel bearing grease. Lots of the GP stuff is only rated for *non*-disc (ie drum) at a lower temperature, and will break down at higher temps which is bad juju.
