Help with flex disk driveshaft coupler guibo
My G37 coupe 08 5AT have a vibration
and i found that flex disk, driveshaft coupler or guibo has totaly cracked.
no is my, but is very similar poor condition.
and in the FSM pag 15 http://www.nicoclub.com/manuals/G37/Coupe/2008/DLN.pdf say that, never remove " Never damage propeller
shaft rubber coupling " this part not have replacement
not is solution viable buy another driveshaft only for a damage flex disk.
not is good idea buy another driveshaft in ebay. because only g 08 5at have a flex disk. are 10 year of hard drive.
I pulled the driveshaft and measure are:
sleeve hole: 12mm
diameter from center hole 115mm
trickness of flex disk are: 30mm
here attach more information about flex disk
here catalog of other brand that use flex disk joint.
https://www.powertrainindustries.com...20Flex%20Discs
my idea is buy from another brand and put on my G
the most similar is
GAD-134 Mercedes 110mm 6 12mm 35mm
GN-132 Mercedes Benz 110mm 6 12mm 26mm
GAC02-004 Chevrolet 110mm 6 12mm 38mm Camaro V8 2010-2013

Many others are in the same boat. I have similar measurements and was looking at this eBay product made by Dorman. https://www.ebay.com.au/itm/Dorman-D...4AAOSw95FZawFS.
I may pull the trigger and test fit. Thank you for the time taking to make this drawing. May need to STICKY this info some day.

I would consider a metal replacement if that is what it takes to get your car back on the road. I have replaced the differential bushings and transmission mount with urethane parts as well as installed the Z1 rear subframe bushing stiffeners yet find the NVH change to be quite small. I suspect replacing the guibo with metal won't affect NVH much, either.

i found for lexus. this
but what's will happen? with the stress in the joint in the driveshaft...

aluminum is softer than steel. if anything the stress from the drive line will wear away the all aluminum coupler disc. the rubber style flex discs take the place of u-joints on a driveshaft. i would not suggest using a solid piece like the one you have in the pic. i would just try and find a flex disc with the specs closet the original one that came off the car.
