The pullies fail because at high speed the outer race should not be spinnig, it should be fixed and the inner race spinning.
High speed spinning outer races cause the grease to extrude though the outer race to seal interface. That is a static seal, but with head, centrifugal force and time it leaks. Some have applied sealants to that interface to deal with the problem... long term results unknown.
A setup with a fixed outer race and spinning inner race could be created, but it would be expensive and complicated.
This problem is not unique to Saabs.
