according to this it is, but just wanted to verify

so im pretty sure its a bad bearing, had a friend come take a look at it.
just wondering if anyone did a rebuild of the V2 for a C6. How much the kit was and how much the labor was (remove and install, and labor to rebuild it)

Did the bearings on my D1SC on my C5. The bearings were less than $20 from car quest and about 2 hours and 2 beer labour
