My ML 320 caughed up the center of it's harmonic balancer last night. Rubber bushing is shot but everything else appears to be unharmed. Serpintine belt and all it's friends look fine.

Read all posts and have a few questions for the informed.

May I just replace the rubber bushing or do I need a new pulley wheel?

Estimated cost of part?

Difficulty level for shade tree tech with a box of Sears tools?


Mucho thanks for any help-
