Worse :( Seal can be easily replaced. They cast Drum Support/Spider part from specially selected alloy with curious property of easily Dissolving in washing powder :)
Drum spider corrodes and falls apart, incidentally it is often the Only internal part not covered with anti corrosion paint :), and drum itself is obviously stainless. For comparison something like Miele is all stainless.
Audi (VW group) 2.0 TDI BLB Engine is made to fail at ~200K no matter what you do, from oil pump to head micro fractures. Crankshaft sprocket at 200K http://lh6.ggpht.com/_m_33vQTtsxM/SyuSlFIeSXI/AAAAAAAAG9o/rt...http://lh3.ggpht.com/_m_33vQTtsxM/SyuSn5YALLI/AAAAAAAAG9s/ul...http://lh3.ggpht.com/_m_33vQTtsxM/SyuSp1yUs4I/AAAAAAAAG9w/mO... VW answer: this part is non serviceable, whole crankshaft needs to be replaced :D Why is it made out of putty while smaller sprocket (the one taking more force) is still 'working'? Why is it designed not to be replaceable? Good 'old timer/not by the book' mechanic is still able to replace it (heat whole crankshaft, use big hammer). 200K is usually first crankshaft turn/grind, engine block itself is good for >500K easily.
