you wore out the poor girl backing up a lot eh? lmao
My dealer found the issue and then some. The reverse issue was due to a worn bushing on the gear not allowing it to mesh properly to go backwards. On top of that the chain adjuster in the CC was trashed leaving a whole whack of metal shavings in the case. In the end they replaced all the drive bearings under warranty.
Your getting close to needing a new drive shaft tooComing up on 8000 km's.
