I tired posting in the 6.7 area but got no replies. Anyone know what the greasable u-joint part number is for a 3rd gen. Looking to replace the rear driveshaft joints on my 07.5. I have one driveshaft...no carrier.
I also read somewhere that the greasable joints are weaker and are more prone to failure then the non greasable units. Any truth to this?

Any help is appreciated.

Well i got the none greasables in mine. I have never tried the greasable ones, but never herd anything bad about them. They are a little weaker cause they have to drill holes for the grease to travel through. But i cant see them being that much weaker. I have a greasable on my front shaft but not the rear. But i did put in presicion joints in my rear one at 120xxx and it has been good so far as im at 209xxx now.

 

Have you tried a driveline shop or Freightliner? I usually go to Pats Driveline for Dana stuff as they can cross ref most any joint.

I don't buy into the grease/non-grease hoopla. If you get el-cheepo greasables, then OK they will be week as they probably drilled all the material the could out of it to save $$$. I have had both grease and non grease with no difference that I can tell. I just did mine at 289,000 and put greaseables in.

 

Cool information...I will probably price at the dealer and a parts store...still would like to obtain apart number for crossing to other brands.
Probably get that at the dealer too.

I "think" the precision # is 351A. I am in edmonton till tommorow night, but when I get back to the farm I will check for sure. I know I had a neapco greasable joint, but they did not quite fit right.

 

I did the rear driveshaft with Napa's in the 04.5. They are greasable and pretty cheap too. Have not had any problems with them.

 

Checkedon the U-joint part number, it is 351A. Precision u-joint. Fit nice, decent price too.
