I was following my wife who was driving the '85 300 TDT recently and noticed it looked a little low in the rear. Since it was full of 8 year olds at the time, including in the 3rd seat, I didn't think much of it. Now after reading several other threads on the subject I'm wondering if maybe my gas charged spheres are getting tired and could use replacing. I would appreciate the input of anyone who has experience with these...is the safety/cost/difficulty to replace make it worth doing soon or should I wait until it gets much worse. BTW the sysytem seems to work fine, I recently took home a load of firewood and managed not to drag the rear bumper. It's just hanging a bit low. Thanks for the (continued) help and feedback.
