JK steering complaints that start as a shake at highway speed usually come back to the front track bar before they come back to the stabilizer. The track bar, 52059982AG, keeps the solid axle centered under the frame. A worn bushing, a loose frame-side bolt, or an ovaled bracket hole is the usual first finding in a death-wobble diagnosis.
The steering stabilizer, 52060058AF, is a damper between the axle and the tie rod. It takes the edge off tire kick and road chop. It does not center the axle, and a new one can hide a loose track bar for a while. If the wheel is shaking hard enough to take your hands off it, inspect and torque the track bar hardware before you buy a damper.
This page lists those two factory parts. Tie-rod ends, ball joints, the drag link, and control arms are part of the same diagnosis and are not cataloged here yet. A stabilizer-only purchase is the wrong first order.

When to replace
Inspect before you order. If the frame bolt is loose, torque it to the spec in the JK death-wobble guide linked below and road-test before you replace the bar. Replace the bar when the bushing is torn, the axle-side joint has play, or the frame-bracket hole is ovaled. The bracket may need work too. A new bar will not fix an egg-shaped hole. Replace the stabilizer when it is leaking or no longer damps small kicks, after the track bar and the rest of the linkage check out. On a lifted JK, a stock-length bar pulls the axle off center. The part page covers when an adjustable bar is the better buy.
Safety
Death wobble is a loss of control, not a noise complaint. If the Jeep has already shaken at speed, do not reproduce it on the highway to confirm. A loose track bar lets the axle walk. Support the axle before you unbolt the bar, torque the fasteners, and recheck them after the first drive.
