Bump, still trying to find answer to my query.

 

Normally both taller springs go on the same side.

But some don't agree the NAS cars need quite the side-to-side difference provided by some of the lift kits: http://www.expeditionexchange.com/ome/indexsprings.php

 

Do you still have the sway bars on? They can be out of wack
Condition of shocks?
bent frame?
The coils are wound tighter at one end are they all facing the same direction?

The ome rears are left right also? Guess I need to check mine

 

I did not check sway bars, think they were OK but maybe my links are bad?

Shocks are brand new, installed with springs. Frame is perfect. Coils are all facing the same direction.

 

Do you possibly have a bent radius arm?
Defective/ mislabled set of coils?

Just trying to throw some ideas
