Did you possibly damage the shock on that side? It's possible that if you flexed it enough to un-seat the spring, the shock reached it's travel limit and the stress damaged the valving inside the shock..... if the shock isn't doing what it normally does, that would explain the loose feeling you're getting. If they were gas shocks, then the gas may have blown out a damaged seal. A fluid shock won't necessarily leak with a blown internal valve.
I remember shearing off an adjuster from a rear RS9000 shock on my rig and it was looser than the one still adjusted firm, gave the rear an odd diving, squatting feeling when driving on the road.
