Toyota part #37511-24010 both ends, $127.00 apiece dealer on Ebay OE. Crazy price but it’s a “Lexus part”. I haven’t been able to find a xcross to other make/model for this part. Some guy in England says it crosses to new style Ford work van but i haven’t found it over the years. YMMV unless your have a 2 post and decent impact and don’t mind doing it again soon. I would replace that part with OE on both ends driveshaft. China rubber is crap. Toyota callout on this part is “Flex Coupler”. “Guibo” self appointed BMW masters of engineering universe. I race a E30 and Dorman is crap on Guibo. Old stock Febi is good. OE is good. Dorman no good. OE or you will be back in there soon afterwards. Be sure and take a look at the part application direction arrows or will be back in there soon also. You can get a few remove and replace out of the self locking nuts if you care too from experience. The MX manual says replace after one use but from experience a couple of r/r works fine. Witness mark the driveshaft parts. Replace the center carrier bearing assembly while in there. Saves grief in the long run. I’m not a “OE only” disciple but on the rotating mass parts such as this it’s wise from my experience on luxury cars and maintaining a vibration free motoring experience for a long length of time.
