Subaru Problems? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The clutch disc has worn out and will need to be replaced. If you have been driving it while it was slipping so you have to rev the engine to move the flywheel will need to be replaced as well.
Budget about $650 to have the complete job done which involves removing the transmission.
Please let me know if you have further questions
