I have done theese bearings on two of my friends gg lately. One 05 where there was much damage in the gearbox, and one 08 where there luckily was just the bearings. This has made me a little bit paranoid, so when I notice some new whining in my 10 s gearbox when in third and fourth gear I fear the worst. Maybe do the Job just as precaution? What do you think?
