Drive shaft lubrication

Reading the U joint couplings and center bearing should be inspected and lubricated,... sans any guidance for the type of lubricant and correct application.

Thanks for any help : Types, sprays, wiping or compressor air off excess.

Lubricated for life. Life of the bearing it turns out. You can't really lubricate any of them. Theoretically the center bearing, but by then the bearing is usually worn and the rubber on it's way out. The U joints? No way. Run it until it starts vibrating then get a rebuilt D/S.

Agreed, they should be replaced as a unit. During my research on driveshafts I read that replacing the center bearing isn't always a solution, because the non-replaceable U-joints get worn, and will cause accelerated wear on the new center bearing. But if you get an aftermarket driveshaft, most of them have replaceable U-joints. Rockauto has new balanced driveshafts with center bearing and replaceable U-joints for $300 which is a good price.
