driveshaft lube question

I have a 2007 Reg. Cab 4X4 and have a quick question about lubricating the drive (propeller) shafts. This truck has the single rear drive shaft. The manual references using a moly fortified grease to lube the slide yokes. I can't find any zerk fittings on the slide yokes on this truck. Are the slide yokes "permanently" lubed on the 2007 Reg. Cab? The 4 universal joints all have zerks. I've been using Mystik JT-6 Hi-temp grease on the U-joints.

 

Did anyone chime in? I use Mobil1 red synthetic on the whole shootin match.

 

Maybe ? I have a DC an it has 2 shafts, a total of 5 zerks, I use what ever goes in the gun or is cheapest, because it gets greased every 3000-5000 miles, whether top self or standard, grease is grease, just have enough.

 

Did you look at the END of the shaft? Sometimes the zerk is located at the end of the shaft inbetween the ears at the u-joint end. Just guessing....

 

The slip yoke is permanently lubed. There are only grease fittings in the joints.

BTW, only 4wd's have grease fittings. The driveshaft on 2wds are sealed.

 

Thanks PB, I was thinking this was another damned thing I had to do this weekend.

 

how often does everyone grease. and where are all the fittings located? i've been taking it to the dealer for oil changes because my back doesn't do well in 6" of snow or -temp concrete

 

Answer:

Every oil change is a good idea. Or at least twice a year.
