The ball broke off the piece that mounts to the hatch. So I'm down to one support and it doesn't work well. I'll probably replace them both, so if someone has Part Numbers they're willing to share. . . that’d be great!

It looks like there was some rust build-up in the ball and socket. The additional friction caused too much stress for the ball to remain attached to the pedestal. It seems my negligence in lubing that joint caused the failure. If you're reading this. . . lubricate the ball and socket on your rear lift supports, so you don't wind up in my predicament.

 

Good tip - thanks!

 

Thanks for the info.. Think i will do that tomorrow.
