My 01 Expedition has the Air Ride suspension on it, would it be possible to go to a junk yard and get the coils/spring suspension from a same generation expedition to replace the air ride??

 

I wouldn't because the coatings that prevent the squeeking and such will have wear and weather checking. Not to mention the fun of pulling dirty parts off in a dirty junkyard with no guarantee.
There are quite a few conversion kits out their for around $220 and you get all new nifty stuff, squeek free. http://www.suspension-alternatives.c...parts-s/75.htm ...scroll down to the second row on the right.

 

When your vehicle came with air suspension from the factory, the rearend and chassis are set up for air springs....not to hold a coil spring. The BETTER coil conversion kits include a coil spring that is specially made to sit in the seat the air spring used to sit in. Makes for a quick and quality installation.

 

Thanks everyone

 

Got my kit from Suncore Industries, good prices and lots of options, fairly easy to do as well.

 

I would just get the new air bags from American Air. Coils don't allow the vehicle to auto level and since I tow a small camper I really like this feature. It's always level no matter what. I replaced mine a couple of years ago & still working great.
