Just buy a new CSB and guibo. It's very straightforward and easy to change. Make sure to MARK the driveshaft pieces so they go back on the same exact way.

On mine I just replaced the actual bearing because the rubber support was still good on mine. But the replacement CSB you can buy would fix your problem. The likelyhood of your rzeppa being bad on the shaft is rare. But the rubber on the guibo is likely to be worn out and cracked which is probably causing your issue.

$950 for replacement parts is unrealistic.

Guibo: circa ~$100
CSB: circa $150 (you can find cheaper options around $50)
Exhaust gasket: circa $20

The carbon fiber driveshafts are simply not worth the $2k+ cost.
