Hi I have a Santa Fe 2009 turbo diesel. My internal throw out bearing is leaking so it means a clutch kit. Now I had my fly wheel replace a couple of years back and it's a dual one, the place I called for a quot reckons I need to have a single mass. There is nothing wrong with the flywheel so I'm thinking why? But is there any great reason why I should spend the extra $500 they want for a single flywheel when at this stage nothing is writing with the dual mass? Opinions would be appreciated hah it's so hard when I don't know much
