Wheel/axle problem - Tire stripping on passenger rear axle

[Crafter]

2011 int prostar with 500k.

But, I have to say, I bought Japanese tires this time, but last time before all this mess, I had 180$ Chinese tires that lasted me 180k, I kid you not, I had those bad boys for 2 years.

I have a feeling Rawze got it right, The issue is the guy only adjusted the bearings on one side. Not both. I'll have it checked out asap.

Thank you everyone!
