Since this thread is back from a couple months ago, I'll add the following.
The tie rod and drag link ends may seem loose if you can easily twist them.
However, if you grab the rod and get no up and down movement in the joints, they are perfectly fine.
Here's how to test the ball joints:
Radial (side-to-side) movement in the upper ball joint should not exceed 0.060" (1.5mm).
Axial (up and down) movement in the lower ball joint should not exceed 0.050" (1.25mm).
A dial indicator is the best instrument to measure ball joint play.
Jack the front tire off the ground.
Place a jack stand under the axle next to the jack.
Lower to put some weight on the jack stand.
Place a long pry bar under the tire, from the side.
Have someone pry the tire up and down while you watch the lower ball joint for up and down play.
Axial (up and down) movement in the lower ball joint should not exceed 0.050"
Have someone grab the tire at top and bottom to wiggle the top in and out while you watch the upper joint for side play.
Radial (side-to-side) movement in the upper ball joint should not exceed 0.060"
Even if the upper joint checks good, change both if the lower checks bad.
