Hi,

Today , I dropped off my 2006 330i (6 speed) with 140K miles for a Rear Driveshaft Flex Joint(guibo) replacement and ground cable upgrade. While replacing the driveshaft flex joint, is there anything else that needs to be replaced / checked as part of preventive maintenance?

Be sure to replace both flexjoints, there's one at the front and one at the rear on the 06' 330- each is a different part.

I wouldn't bother with the front one - it sees way less wear than the rear one because it runs almost straight all the time. Certainly inspect it though.

Have a look at the rubber around the centre bearing - mine was hanging on by a thread when I did my rear giubo.

I just say to replace both because they're relatively cheap compared to the amount of labor it takes to replace them, at least by doing it the normal way with dropping the exhaust and heat shields. For 10 minutes more you may as well replace the other, by my logic. For some reason my front one was worse than the rear- likely due to tired transmission mounts causing the trans to sag a little bit.
