The front flex disc is under a lot of load. It takes the place of a U-joint in domestic cars. You may want to check the rear flex disc while you are down there.

It was a little dirty and took about 2 hours going very slow. You may want to just put the car up and see the disc before you order parts. Mine completely fell apart when I unbolted the bolts. It has about eight grade 8 bolts.

Good luck,

Nick
