I have an 02 Olds Bravada and my compressor quit working. I took it to a mechanic and for 150.00 he replaced the air bag system with coil springs. Much better in my opinion.
It has shocks.
This car does not come with air shocks.
OEM shocks were usually black.
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.
Probably has air shocks on the rear and fuse controls the on board air compressor
Not if they are struts - need a spring compressor
Bad shocks
Yes, and you might want to do that if you air compressor is not working anymore. If the compressor is working, I would suggest continuing to use the air-shocks since you get the benefit of a load adjusted ride. I have used both Monroe and OEM AC Delco shocks, and they both work well. If you go with non-air shocks, make sure you disable the air compressor by pulling the fuse, etc. Otherwise the compressor may just keep running.
you will hear it run
The 4Runner doesn't have struts; it has coil-over shocks in front. After removing the old shocks a spring compressor is required to remove the springs and install them on the new shocks. Take it to a front end shop that has the proper compressor and tools; it's very dangerous if you don't have good equipment and experience. The rear shocks are easy to replace by yourself.
That is the air compressor for the ride leveling feature. It adjusts the rear air shocks when the back seat is occupied, or when passengers get out.
the rear shocks on the newer Envoys are air shocks, and wear just like the other ones, however there is also a compressor in the system that is prone to failure.
