Yes. Those might just do the trick, but before you start replacing any parts (those things are actually pretty reliable) you should find out for sure with 100% accuracy just what parts are loose.
I say "parts" plural because most EB's suffer from more than one thing contributing.
I'm sure you've heard it many times, but still the easiest test is to, with the full weight of the vehicle on the ground, have a helper turn the steering wheel back and forth enough to make the tires turn slightly. They don't have to go lock-to-lock, just enough to highlight any loose parts. Maybe a half-turn in each direction for most.
While they're doing this continuously you're poking your head under the hood and laying under the front inspecting each and every component that is attached to some other component.
From that shaft, to the frame behind the steering box, to the draglink and tie-rod, to the trackbar and it's mounts, to ball-joints, the wheel bearings and even the wheels themselves.
Anything that has play is bad and needs replacing.
That sounds kind of dire, but literally every steering component is not allowed any side to side motion without moving the next component in line, or it's worn beyond it's service life.
Do this test and you'll see everything and anything that moves.
Including anything in the rear end that might be contributing to the less-than-tight steering feel.
