The Mercedes official shop manual says "... turn the nut (with a rubber boot) on the driveshaft two turns ..." Is this necessary to do when removing the drive shaft to replace the flex disks. The nut is too big for any of my wrenches, and there is very little access to it because the catalytic converter is in the way. I'm hoping that I will be able to drop the shaft down, without this missed step leading to problems later in this job... Any suggestions??
Man ... are these nuts tight on the rear flex disk! Any tricks to getting these things loose?
Should I replace shaft seals on the diff and transmission while the driveshaft is out? I know they're inexpensive seals, but is it difficult to do?
