Cracked Drum On LG Dryer

I ran into same problem.On a LG DLE0332W.

First went over, dryer thumping......thought rollers...

Ordered parts...took dryer apart to change out rollers

and I see the rollers look new and not the problem. 

I noticed that the drum had a split on the weld... and a crack.

I'm not sure how old this dryer is but I'm wondering if this would be a

manufacturer defect  on the welded joint and under warranty. 

Would LG send a new drum.

How would I go about finding out...

Any LG TECH. That could help.

Thanks 

I'll let the customer know.

I think there about $170.

Thanks
