[Fot] Greasing spicer u joints

[Scott Janzen]

The GT6 has spicer u joints on the halfshafts and on the driveshaft. I have the entire rear end disassembled and am now inspecting the ujoints. They look good, no visible wear and there was no play in them when on the car. Do i just pull the cups and put some more grease in, or should the little buggers be totally cleaned, needle by needle and re-lubed?
I’m always reluctant to change the order of anything, i.e. mixing up the needles.
No way to flush them out with grease as one does with the ones with a grease fitting.
Thoughts?
