Broken kingpin

Pins of Oz Dufor manufacture have poor reputation here. Poweful brakes not entirely a blessing. The bits more securely retained with the pre Girling hubs.

The king pins rust because they are greased with a grease that is not waterproof. I raised this on the old forum years ago but got shot down in flames.

Use a grease that is waterproof, i.e. a calcium based grease, used to be Castrol CL but others have to be found now that Castrol have run away from the market. Lithium based grease forms an emulsion with water, leading to the damage (but not the breakage!) in the photo. I know we all have our favourite greases, oils and whatever but using a waterproof grease on the exposed chassis parts will stop the rusting illustrated.

I'll go and take cover - prepare for incoming!

P.S. tried silver steel kingpins years ago, when the debacle of overhardened, 10 thou undersize, tapered kingpins was running. They broke within 500 miles.
