The flex disc (aka the guibo) connects the driveshaft to the transmission and provides a buffer to absorb driveline vibrations. The rubber flex disc takes the torque coming out of the transmission and delivers a seamless transition to the driveshaft. But over time the rubber is subjected to constant loading/unloading and it will break down. The rubber is designed to be the weakest link so that the rest of the driveline lasts longer.

Symptoms of a failed guibo will be a dull thunk when dipping in/out of the throttle and during shifts. You may also notice cracks in the rubber around the bolt holes. A great time to replace the guibo, and driveshaft center support bearing, is during a clutch overhaul, short shift kit install, or any time the driveshaft is removed from the car.

Install note: the flex disc may be directional. During install, look for an arrow on the outer rim. The arrow should point towards the flange and indicates the direction the bolt should go. Installing it backwards will cause premature failure of the flex disc. Because this kit fits multiple different models, it includes extra hardware. If you choose to replace your original hardware, match up the bolts and throw (recycle) the rest away.

This flex disc is a Heavy-Duty design from Meyle. Meyle HD parts are designed and engineered in Germany using an OE+ approach. Meyle engineers use the original design but with several improvements in materials and design to make a guibo that lasts longer and performs better than the stock link. Meyle HD parts are true upgrades that surpass OEM parts but without compromises to noise or ride quality. Meyle HD parts are TUV approved and have a four year warranty.
