172 Hub

[mantis946]

Hiya,

Just had new front bearings pressed into the PH1 hubs and noticed one of the connecting arms for the calliper has bent. Anybody have any idea what material the hubs are ? I thought there were cast iron but from what I've seen, cast iron does not like to bend ! Hoping I can heat up the arm in a vice and straighten it back out.

Cheers

I wouldn't fancy reusing a bent caliper mount, theyre cast steel but theyre not going to take too kindly to being bent and reformed you'll just end up work hardening the material, making it susceptable to fatigue. I can only assume that the bearing was very poorly supported when the bearing was pressed in.

I'm quite surprised they bent in the first place given the strength of them, however I suspect you are correct regarding how. I'd like to avoid replacing them if possible, the front bearings are pretty steep for what they are, not to mention I've just spent an arm and a leg replacing all of the suspension and steering with an engine and gearbox build still to go !

Take it back to who ever did it and complain. It's up to you ultimately but I certainly wouldn't run it on any of my cars. It's not worth the hassle.
