BMW Guibo Problem Flex Disc Joint Failure

Does your BMW vibrate when driving at high speed or has an unusual noise from under? Follow the procedures below to learn how to fix your BMW.

---

BMW flex discs may fail on high mileage vehicles, which results in loss of power (propulsion) and loud noise from the rear drivetrain. The BMW flex disc is called the guibo disk or constant velocity joint. It transfers power from the transmission to the rear driveshaft.

Symptoms

The rear driveshaft constant velocity (CV) joint on certain BMWs may fatigue and break.

Some symptoms include:

• BMW driveshaft/flex disc / universal joint failure
• Vibrations at high speed
• BMW won’t move if guibo joint has failed
• Unusual noise from the underside of BMW

How to change a BMW Guibo Joint

To fix this problem, your BMW dealer or your mechanic must replace the 26117610061 flex disc.

The flex disc is between the transmission and transfer case and will need to be replaced if it hasn’t been replaced.

The bolts should be replaced as well. If a recall covers your BMW, the BMW dealer will replace the flex disc free of charge. Make sure to replace all six hexagonal head bolts and the self-locking nuts.

Recall

According to recall 17V-067, BMW states, “The flex disc may not have been produced with insufficient strength.” If this problem occurs, the BMW will not move when placed in gear.

If the flex disc joint breaks while driving, it can cause damage to the underbody of the BMW.

Vibracoustic in Germany manufactured the defective flex disc. Approximately 8750 BMW vehicles are affected by this problem, according to a recall SI B26 01 17 (2666), 17V-067 (2667).

Don’t ignore this problem. As your BMW ages and you put more miles, the constant velocity joint may break while driving, causing an accident.
