Is this a triangulated 4link or do you have a Panhard rod?

Make sure your panhard bar is level at ride hight.The more it is level, the better it will feel. If you have triangulated four link,You shouldn't need a panhard bar.

The wrong pinion angle can cause a lot of weird issues.



It can be used as a tuning tool also for traction ( launch )
Offset of the pinion ( side to side ) can also cause problems.

Like already stated, you do not need a panhard bar ...

A panhard bar with triangulated 4 bars or 4 links will cause a bind in the suspension.

Not good. Even so, if you added a panhard bar and it still feels sloppy, there are other issues.


How far apart are the links on the rear end and , what are they bushed with? Whose setup is it? A Chrysler New Yorker is a big car with a big overhang on the back, and would need some stout bars and ends and a fairly wide spread mounting position to keep things under control.

The airbags on top of the axle should not cause any problems like that..And driveshaft issues severe enough to make the car sway would have broken the driveshaft by now.


Can you take some pictures?

Later, mikey
