The side going down is the side that has the cracks in the fold and it is usually noticed in cold weather when it starts. When that one side goes down, the other side doesn't have the strength to hold up the heavy front end on it's own.
You can, (when money allows), switch to the Gen 2 style air shocks. I have them on mine and the ride is a bit better than the steel Gen 1 style. If you get new ones, you should be worry free for around 15 years. IMO, it's worth it because I like the air ride, as do many others.
