Air shocks allow the vehicle to ride smoother than regular shocks. Also, it helps the car carry greater weight over longer distances than regular shocks.
Yes you can.
You have to replace with springs and shocks
Yes you can.
The Oldsmobile van has struts on the front. If it has air suspension, then the rear has struts as well. If not air ssuspension, then it just has regular shocks.
Yes. Just look up " strutmasters.com " They have what you are looking for.
You could do that. The air shocks would have to be manually inflated. You may run into a competition between the manually leveling system and the automatic levilng system.
None but some people use the T-Bird springs and shocks.
The shocks on the Town car are actually regular shocks front and rear and are separate from the air springs. They are fairly inexpensive. The rear has air springs rather than mechanical steel springs. Do not mess with them if they are working. Replacement air springs can be purchased from http://www.arnottindustries.com/ for around $100 each and they will last for another 10 years. If you can change spark plugs you can change an air spring. Arnott gives detailed instructions. Don't be afraid of the air suspension, it is much superior over the steel springs.
This car does not come with air shocks.
They have air shocks in the back that are used for ride height control. This is not the same as an "air spring" system. They have regular rear springs and the air bladders in the shock are only pumped up when there is significant load in the rear, to prevent the rear end from sagging. This is a very simple and reliable system. Monroe makes great factory replacement rear air shocks and they are cheap too.
If you are looking to make air shocks operate like air bags, you will be disappointed.
Below is a link to the instructions for that installation.
