Here in the States, our auto parts stores sell grease that is labeled for wheel bearings. Given the speed and use that your truck will be experiencing, I think any good quality grease such as would be used to maintain farm or factory machinery would work fine.

Wouldn't there be a seal of some kind as well?

From the photo it appears that there is too much grease in the hub. Found this online which describes the issue. "Too much grease can cause churning of the grease during operation and high temperatures, resulting in overheating and leaking. As the operating temperature rises, the breakdown rate of the grease increases, doubling every 18° F (7.8° C)". I would be more concerned with proper bearing packing procedures as long as you use a good wheel bearing grease.

Hi Thor

I'm guessing from your name and the newspaper that you are either i Danmark eller Norge?  🙂

First, for what it's worth, anything I say will be based on 2 years of training as a farm machinery mechanic, and 47 years of learning what works and what doesn't as a farmer.

Tiny is right, there should be a seal.  It will probably originally be made of felt, but a replacement made of neoprene may be available.

There should also be a sheet metal plate on the brake drum (which does appear to be there in your picture) which is supposed to capture any grease that leaks past the seal and guide it through a hole in the hub to the side of the hub away from the brake area.

The inside of that plate and the hole need to be clean and free of old caked grease etc.

Most multi-purpose greases are now lithium complex soap based greases and will work just fine for this application and not churn into a liquid.

Thickness is rated as an NLGI number and #2 will be what you want.

I'm not sure what is available where you are, but I use Shell S3 V220c 2.

I was taught to pack the bearings with grease, and put a thin film on the inside of the hub and on the spindle.

My experience with the results of water and condensation in wheel hubs has shown this to be WRONG.

Also, when done this way, centrifugal force naturally forces grease OUT of the bearings and into the hub and dust cap and frequent repacking will be necessary.

I now pack hubs and dust caps nearly full, and haven't had any resultant problems.

And once done that way, an occasional removal of the dust cap for inspection and possibly a little take up has always shown a removal and repack to be unnecessary.

All this is just my opinion, but I hope it helps.  🙂

Thanks for all your feedback. Very good information. I will probably use Delo Starplex EP2. And I will pack it well. Delo Starplex EP 2 | Texaco Lubricants | Chevron Lubricants (Europe)

By the way, I am the guy from Oppdal, Norway. I have now registered the correct way

Hello there!

Sorry I didn't recognize you right away.

The Delo looks like an excellent choice.

Hopefully some day I will get to meet you and your truck!  🙂

@ole-olson 

Just come across. Will be glad to host you and wife.

Just received several packages, so started the rebuilding phase
