But that doesn't look bad - and the corroded bit where the metal bracket is bolted is more likely due to the failure of the coating on the steel part.
I'm still in the camp of you do more harm than good be removing an existing, long lasting surface finish on aluminium.
Speaking of ali Alfa 159 front suspension - if yours has aluminium yokes connecting the shock to the lower arm - don't over-tighten the pinch bolt when you reassemble - which no-doubt will be corroded in place, as will the shock tube - heat, vibration got that out
I don't disagree, but the big issue is galvanic corrosion.
The hubs are steel and the carriers are alloy so it’s asking for trouble.
They don't paint the hubs so when you add an electrolyte you have an nice cell that will eat away the alloy.
Where the the electrolyte is excluded by the nice machined faces, the casting is pristine. Just beside, it's not.
I'll know this has lasted well enough and probably longer than the bean counters at Alfa calculated, but if you want to get a a car to last longer than it normal disposable design life, you need to do a bit of preventative maintenance or be prepared to replace loads of parts.
The yokes on mine are steel.
Came apart no problem and got the grit blast, Jotamastic and Hardtop HB treatment.
Should be good for another 15 years.
Was it only the Q4s that got alloy yokes?
I suppose every kg saving in unsprung weight helps.
Alfa have history on this, who else would put inboard discs on a mass market supermin.
I still have the 6mm spanner I cut in half 40 years to get at those hateful adjusters.
