Jost 5th wheel Pivot pins

...I notice lately my JOST 5th wheel doesn't pivot anymore after unhooking my trailer, there are no grease zerks on either side of the 5th wheel, so i asked a buddy, and he told me the pivot pins get their grease from the top of the 5th wheel in the square cavities on either side of the 5th wheel directly above both pins. So my question is, is there anything I can do to get my 5th wheel pins to pivot anymore. Or will they need replaced? I'm thinking I should dig the grease out of the cavities and clean it as best i can an replace with new grease. Thanks

 

Yea thats what I kinda figured...I told my mechanic to just get a 5th wheel kit coming for it, while we're doin the pivots, might as well do 'er all...thanks!
