Chra??

Central Housing Rotating Assembly.....the spinny bit of a turbo

Ahhh..,.thanks!

Dunno about replacing one though

Had me wondering too

They are quite easy to do, mark a datum point on the turbo casing and take a few photos before taking it apart just so you can align it correctly when putting it all together again.
If i remember right 4 bolts and a large snap ring is all that holds them together.

Yea looked on utube and they look easy enough, was just wandering where the best place to get one from as I don't want to buy Chinese rubbish.
