Almost fit my Trailblazer SS
I ordered the part for my Trailblazer SS. It fits but the connection for the end links to attach was too small because I have the larger heavy duty ones. If you have an SS, you can either drill the hole out like I did or you can find one of the manufacturers that offers one with the 18mm hole.

Why isn't there a grease fitting for the ball joint?
Donald F on Nov 3, 2015
BEST ANSWER: Hello, Not all manufacturers have grease fittings installed. They come pre-greased and sealed from the factory so they are a no maintenance item.
