Hello Jean,
Let us know how the yum cha hub goes. I did that once
It had play in it from the beginning and got worse very quickly. Within 7,000km it was toast. Keep in mind there was a lot of mud, ruts, roots, bash bash bash bash in those 7,000
I then put Timkens in, from RockAuto. Zero play.
Hopefully you have a better experience than me with the yum-chas
