I've got a 83 chevy K20. My best research says it should be a Dana 44 front end, but please correct me if i'm wrong. How do i grease the upper ball joint?!? It appears that there is either a grease fitting or plug on the bottom of the ball joint directly above the u-joints, but it is completely inaccessable. i have thought about stabbing the boot with a needle and greasing it that way, but i'd prefer to do that only as a last resort. I have no wish to take it apart either. it probably never has been, and i don't think i have the fortitude nor the tools to break free almost 30 years of rust and neglect. just doing my pre-winter rounds before i have to hang the plow, or fix it in the snow because i neglected it too long. i appreciate any help!!! Mike.
