Front Hub Corrosion!

[304065]

Wow. I went to install front wheel bearings and found this. . . never seen corrosion like this before. Compare to a known good hub.

Ordinarily I'd just bead-blast it off, but this is the machined mating surface for the disc, I can just imagine imbalance problems resulting from a surface that's not true. I suppose I could chuck these up in a lathe and make a truing cut (that's what the Factory did to machine them, look at the marks in the good hub). . . or just source a good set.

Sooo, just how many years were those at the bottom of the Atlantic

Ed, how did you know these hubs saw action in the battle of Jutland? They will make great paper clip holders once the studs are pressed out . . .

I think I have a pair of SWB front hubs.

PM me if you need a pair.

That would throw your rotor off center in the caliper.

They tend to corrode quite well....
here are mine;




They will be replaced...

That is a great image of the fatigue/stress cracking that we may all need to be aware of. I would expect if you were you test these with magnetic particle (magnaflux), there would be other cracks not visible to the naked eye. This is also a good reason not to chock them up in a lathe and re-use them.

These really suffer from heat and galvanic corrosion. I think it is a good time to stock a spare set for a rainy day.
