Bad compressor? Blown fuse? Broken air line?
Probably has air shocks on the rear and fuse controls the on board air compressor
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 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.
Most Montana's have a rear air suspension in them (air shocks). The compressor is there to adjust the rear height of the vehicle depending to weight in the van.
Rear air shocks work by using a small air compressor to provide additional lift and support. This is particularly handy for towing heavy loads.
I believe that the rear air shocks are part of an automatic level control system. There is a level sensor on the rear suspension system and a compressor that fills the shocks to raise the rear end. There is also a valve to release the pressure to lower the rear end.
Most of the time the air compressor is locked up.
I need to pull the fuse on the air compressor on the air shocks, 1 is leaking and motor kicks on a lot.
The compressor automatically turns on and raises the pressure as rear axle load increases. The switch found in the rear compartment is for using the compressor for filling tires after attaching the supplied hose.
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.
