That's what I was afraid of.You can not fix that type of play with out taking the box apart. Either the bearing has failed, the shaft is worn, or the box it self is some type damage from a combination of worn components.
The 6 bolt uses a larger sector shaft and bearing along with an additional bearing on top to help support it.
Unfortunately, It doesn't matter Who you buy it from here in the USA, They are still manufactured in China...
