Was thinking of changing out the supercharger coupling on my 2013 with roughly 75K miles. Has anyone done this as preventative maintenance? Is it worth the cost or should I wait until I start hearing some noise?

Yeah same as the isolator, i was thinking of changing just the oil but then figured maybe I should change the coupling as well before I put new oil in. Is this something that can be done myself with basic tools or leave up to a shop?

yes gasket is a liquid gasket and the oil would need to be drained and replaced after. The oil is pretty simple to change. just thinking while it is drained if worth the effort to change out the coupling since it is prone to failure. i have heard the Poly holds up better and had increased damping properties. I was thinking this could somehow be done by just undoing the bolts and just moving the snout forward but i don't think it is that easy.

Thanks Ed,

Looks like I was looking at the process for the 4.2 engine. The 5.0 had as totally different supercharger TVS1900. So did you change the oil while you were in there?
