I thought my turbo went bad so bought a new ko4 before i pulled the old one
but when i did pull the old one i
found no shaft play at all but had a bad actuater but was an aftermarket ko4 aswell so just put the new one on an called it a day.
I will have pics tom and the turbo dosent look old and has no shaft play but actuater is bad and will need replaced there 40$ and not hard to install 100$ or best
