Aftermarket replacement parts will come with grease fittings such as tie rod ends, ball joints, etc.
From the factory a 2005 Liberty did not have any grease zerks.
Zero from the factory.
11 grease fittings
You grease the suspension on a 2005 Chevy Trailblazer by attaching a grease gun to the grease fittings. Grease is then injected into the fitting until it leaks back out.

There ARE no "grease fittings." All the parts are, supposedly, lifetime lubricated. To me, that means the "lifetime" of the individual parts. Another case of semantics.

only one on rear drive shaft.
The lower ball joints have grease fittings especially if they're aftermarket so you may want to keep those lubricated.
If it has any they would be on the tie rods and ball joints.
