Re: [diesel_mercedes] Flex disk vs. u-joint

 

Flex discs and u-joints are two different things, and your '85 300Dt has both.  The driveshaft couldn't be run in a straight line from the transmission to the differential, so there's a u-joint in the middle.  The flex discs are at the connection to the tranny at one end and the differential at the other.  Each of these is held on by 4 bolts.  The discs are rubber and are sandwiched between the metal plates on the driveshaft and couplings at the tranny/differential.  They absorb any vibration and driveline clunks when shifting into drive, reverse, downshifting, etc.

[diesel_mercedes] Flex disk vs. u-joint

 

Is there a difference between u-joints and flex disks or is it another way to say same thing? I am having carrier bearing replaced in a'85 300DT and am seeing references to both of these in addition.
Thanks in advance,
Giancarlo

what's a 340? The kids love mud season. They come home with mud from the tip of whatever they are driving to the tail. Jasper says it a "badge of honor". Max
