[W126 Coupe] rear flex disc

[Dick Spellman]

Hi David:

When I've done these with my mechanic (3 on the 126 chassis  now) I've 
dropped the driveshaft (carefully marking the splined shaft) and 
replaced both front &  rear flex disks and the center support bearing 
all at the same time.  Where you have to pull the exhaust and driveshaft 
cover it's just too much work to only do one piece in my opinion.  Be 
real careful with marking (painting) the driveshaft halves for alignment 
on the splined shaft for EXACT re-assembly as the factory had it, check 
the universal for free movement should not be stiff or catching in it's 
movement.  Check the rear pinion seal for leaks at the same time and 
replace if it's weeping.  Top off the rear end if you mess with the 
seal.  You may want to order the rubber sleeve (boot) for the drive 
shaft too, it will likely be cracked.
