When you start getting into older vehicles, a steering stabilizer is a good thing. You can have multiple parts individually worn but not out of tolerance. The aggregate of those can cause front end issues. On top of that, it can be hard as **** to find the stock size tire (usually 225/75-15 or 16) for ZJ/WJ/XJ, and they've often been upsized (mine were 235/75-15 on the ZJ and 245/75-16 on the WJ). Extra tire weight does not help the issue.
Long story short, I believe in steering stabilizers for stock DD ZJ/WJ/XJs. No, it's not a substitute for proper maintenance, but it's a part of a system.
If you've torn into your front end and properly rebuilt it with new shit, it's a different story.
