Driveshaft with no zerks

Yahoo Message Number: 63716
The driveshaft in my coach has no zerks except for each universal joint. There is no way to lube the slip joint, as it is covered by a rubber boot fastened on with "permanent" clamps.
I called Spicer today and learned that the slip joint is "lubed for life".
Really??? Then why couldn't the PTO/pump connection use the same lube??? And the kicker was that going through the numerous phone menus to get to the "driveshaft dept", one of the choices was Chelsea PTO's!!!

Hi Roger. If it were me I'd look for 2 zerks at each universal joint 180 degrees opposite. My slip joint is the plain vanilla kind, so my drive shaft has 5 zerks . . . lube um' every 5,000 miles.

The lube for life slip joint has been used for some years. It has a factory treatment similar to teflon. The ones I have seen are blue in color. It works on slip joints but have never seen it on U joints. LIghter vehicles are lubed for life on all joints. Depends on how heavy duty a vehicle is. Our Jeeps have lube joints. Drive lines sealed, for most part. It was believed it was better to seal a joint then have dirt forced into it by bad lube practice. I like the lube for life stuff, sure lots easier to maintain a car over the old lube required days. As for use on PTO. If factory installed, it probably would work. Could be more expensive then a wet kit.

Hi Roger:

One guess at that question is the alleged "hammering" that a diesel produces on idle as each cylinder fires. The PTO is connected directly to an output associated with the flywheel/crank. Not much to absorb that abuse like an entire transmission.
Just a SWAG based on something a former CC employee said - or that's where I think it came from. The bigger the engine the bigger the problem and why the big rigs were recalled - perhaps first. I would suspect that they might have eventualy gotten around to the smaller rigs if enough failures plus gripes were heard. Became moot after the market/bank/mortgage fiascos and CC's demise.

Ours is wet now, no problem bro.
