Does anyone know the driveshaft sleeve nut size on an 86 300E? And is it just one nut or is there a locking nut as well? If so, same size or different size? Is the nut in a gap wide enough to use a crescent wrench if I can't find the proper size open-end? The car is at a remote location and I need to know before I make the trip. Also, can the support bearing be removed and replaced without a special puller/installer?

Thanks,

Gary
