Re: How to check "air ride" suspension - looking to buy used Town Car

Besides, coils or ARS, other suspension components should be taking care of the side-to-side movement. Watts linkage, sway bar, control arms, etc. After installing my 17mm sway bar from a CVPI, my rear end no longer does that side-slip when I hit bumps and potholes.
